Forbes Field Forbes Field was a baseball park in the Oakland neighborhood of Pittsburgh , Pennsylvania , from 1909 to 1971 . It was the third home of the Pittsburgh Pirates Major League Baseball ( MLB ) team , and the first home of the Pittsburgh Steelers , the city ' s National Football League ( NFL ) franchise . The stadium also served as the home football field for the University of Pittsburgh " Pitt " Panthers from 1909 to 1924 . The stadium was named after British general John Forbes who fought in the French and Indian War , and named the city in 1758 . The US $ 1 million ( $ in present - day terms ) project was initiated by Pittsburgh Pirates ' owner Barney Dreyfuss , with the goal of replacing his franchise ' s then - current home , Exposition Park . The stadium was made of concrete and steel ( one of the first of its kind ) in order to increase its lifespan . The Pirates opened Forbes Field on June 30 , 1909 against Chicago Cubs , and would play the final game also against the Cubs on June 28 , 1970 . The field itself featured a large playing surface , with the batting cage placed in the deepest part of center field during games . Seating was altered multiple times throughout the stadium ' s life ; at times fans were permitted to sit on the grass in the outfield during overflow crowds . The Pirates won three World Series while at Forbes Field and the other original tenant , the Pittsburgh Panthers football team had five undefeated seasons before moving in 1924 . Some remnants of the ballpark still stand , surrounded by the campus of the University of Pittsburgh . Fans gather on the site annually on the anniversary of Bill Mazeroski ' s World Series winning home run , in what author Jim O ' Brien writes is " one of the most unique expressions of a love of the game to be found in a major league city " . History . Planning and design . In 1903 , Pittsburgh Pirates ' owner Barney Dreyfuss began to look for ground to build a larger capacity replacement for the team ' s then - current home , Exposition Park . Dreyfuss purchased seven acre s of land near the Carnegie Library of Pittsburgh , adjacent to Schenley Park , with assistance from his friend , industrialist Andrew Carnegie . The low - priced land was selected so Dreyfuss could spend more on the stadium itself . Dreyfuss signed a contract that he would " make the ballpark . . . of a design that would harmonize with the other structures in the Schenley Park district . " The site was initially labeled " Dreyfuss ' s Folly " due to its long distance — a 10 - minute trolley ride — from downtown Pittsburgh , but the land around the park developed and criticisms were dropped . Official Pirates ' records show that Forbes Field cost US $ 1 million for site acquisition and construction , however some estimates place the cost at twice that amount . Dreyfuss announced that unlike established wooden ballparks such as the Polo Grounds , he would build a three - tiered stadium out of steel and concrete to increase longevity — the first of its kind in the nation . Charles Wellford Leavitt , Jr . was contracted to design the stadium ' s grandstand . A civil engineer , Leavitt had founded an engineering and landscape architecture firm in 1897 . He had gained experience in steel and concrete constructs while designing the Belmont and Saratoga racetracks . Based on Dreyfuss ' architectural requirements , Leavitt presented a plan for Forbes Field — the only ballpark he would design . Pirates ' manager Fred Clarke also had input into the stadium ' s design , giving groundskeepers advice on the field , in addition to designing and patent ing a device to spread and remove a canvas tarpaulin over the infield in case of rain . Initial work on the land began on January 1 , 1909 , but ground was not officially broken until March 1 . Nicola Building Company built the stadium in 122 days and play began less than four months after ground was broken , on June 30 . Though the scoreboard was operated by hand , the ballpark featured multiple innovations such as ramps and elevators to assist fan movement throughout the park , a room for the umpires , and a visiting team clubhouse similar to the Pirates ' . The facade of the stadium featured " buff - colored terra cotta " spelling out " PAC " for the Pittsburgh Athletic Company . The light green steelwork contrasted with the red slate of the roof . Some members of the press urged Dreyfuss to name the stadium after himself . However , the owner decided on Forbes Field , in honor of General John Forbes , who captured Fort Duquesne from the French in 1758 and rebuilt a new " Fort Pitt " at the site . In 1935 , after Dreyfuss ' death , there was renewed media interest in renaming the stadium " Dreyfuss Field " . His widow , Florence , resisted . However , a monument to Dreyfuss was placed in center field just in front of the wall . Opening . On June 29 , 1909 , the Pittsburgh Pirates defeated the Chicago Cubs by a score of 8 – 1 at Exposition Park . The two teams opened Forbes Field the following day . Fans began to arrive at the stadium six and one - half hours early for the 3 : 30 pm game . The game started at 3 : 30 p . m . Weather conditions were reported as clear skies with a temperature around 80 degrees . Of the crowd , the " Pittsburgh Press " wrote , " the ceremonies were witnessed by the largest throng that ever attended an event of this kind in this or any other city in the country . . . Forbes Field is so immense — so far beyond anything else in America in the way of a baseball park — that old experts , accustomed to judging crowds at a glance , were at a loss for reasonable figures . " Records show that the first game was attended by a standing - room only crowd of 30 , 338 . Various National League officials and owners were present for the opening pre - game ceremonies , including league president Harry Pulliam , Civil War veteran and manager of Pittsburgh ' s first professional baseball team Al Pratt , and American League president Ban Johnson . Pittsburgh Mayor William A . Magee threw out the stadium ' s ceremonial first pitch . The Chicago Cubs won the first game by a score of 3 – 2 . Dreyfuss declared , " This is indeed the happiest day of my life . " The stadium was widely considered the best in the league . It is more accurate to say Mayor Magee threw out the first ball . He was in the second tier and threw the ball to John M . Morin , Director of Public Safety , on the field below . Morin then went to the mound and threw the first pitch to the Pirate catcher . Pictures depict the flag at Forbes Field at half staff on opening day . This occurred to honor recently deceased presidents of the Philadelphia Phillies and the Boston Doves . The first batter at Forbes Field was future Hall of Famer Johnny Evers , the Cubs second baseman and lead off batter . He was hit by a pitch and later in the inning scored the first run . The first hit by a Pirate was by catcher George Gibson , who eventually became a Pirate manager . Playing field . Barney Dreyfuss " hated cheap home run s and vowed he ' d have none in his park " , which led him to design a large playing field for Forbes Field . The original distances to the outfield fence in left , center , and right field were , , and respectively . In 1925 , the right field grandstand was extended into the corner and into fair territory , reducing the foul line distance from to . Due to the reduced distance , Dreyfuss erected a high screen to limit home runs . Even at this long distance from home plate , the wall stood in height in all around the field , with the right field wall reduced to following the 1925 construction ( topped by the screen ) . The backstop was set at behind home plate , larger than the average of in most stadiums of the time . Additional seating eventually cut down the plate - to - screen distance to a still larger - than - average . With such a large outfield space , triples and inside - the - park home run s were common . The Pirates hit a record eight triples in a single game , on May 30 , 1925 . Conversely , the stadium was one of the most difficult to hit over - the - fence home runs . The closeness of the right field line from 1925 onward was the only area that compromised Dreyfuss ' original design concept . Even at that , the right field wall angled sharply out to , a typical distance for a major league power alley . The final three home runs of Babe Ruth ' s career were hit in Forbes Field on May 25 , 1935 ; the third of these cleared the right field roof and was considered the longest home run in the park ' s history . Although Forbes Field developed a reputation as a " pitcher - friendly " ballpark , there was never a no - hitter thrown in the more than 4 , 700 games at the stadium . The field itself consisted of natural grass grown in Crestline , Ohio . The batting cage was placed just to the left of the center field " Death Valley " marker during games , because it was believed impossible to hit the ball that far . The open part of the cage faced the wall , the back of the cage effectively serving as a convex fence . In right - and left - center fields , light towers stood on the field , and like the batting cage and flagpole in center field , were in - play . In 1947 , well after Dreyfuss ' death , and upon the arrival of veteran slugger Hank Greenberg , the bullpen s were moved from foul territory to the base of the scoreboard in left field and were fenced in , cutting from the left field area , from to down the line and to in left - center field . These were not abnormal major league outfield distances , but the obvious attempt to take advantage of Greenberg ' s bat led the media to dub the area " Greenberg Gardens " . Greenberg retired after the season , but by then Ralph Kiner was an established slugger with the Pirates , and the bullpen was redubbed " Kiner ' s Korner " . Kiner was traded after the 1953 season , and the field was restored to its previous configuration in time for the 1954 season . The final posted dimensions of the ballpark were left field line , left - center field , deepest left - center , deep right - center , right - center field , and right field line . The only marker in exact straightaway center field was the Barney Dreyfuss monument , which sat on the playing field just in front of the wall . Forbes Field ' s ivy - covered walls featured no advertising , except a United States Marine billboard during the 1943 season . The infield developed a " rock - hard " surface throughout the stadium ' s history . During the final game of the 1960 World Series , Yankees shortstop Tony Kubek was struck in the neck with a ball that had bounced off the hard dirt surface , breaking up a potentially rally - killing double play and causing Kubek to have to exit the game . Pittsburgh went on to win the game and the championship . Groundskeepers would burn gasoline on the mound to dry it off . Because of the bounces , Pirates ' play - by - play announcer Bob Prince nicknamed the ballpark , " The House of Thrills " . Seating and tickets . Forbes Field had an original capacity of 25 , 000 , the largest in the league at the time . Seating at the stadium was remodeled numerous times , peaking at a capacity of 41 , 000 in 1925 and closing in 1970 at 35 , 000 seats . On opening day , ticket prices ranged from $ 1 . 25 for box seats and $ 1 for reserved grand stand sections ; temporary bleachers were set up for the occasion and cost $ 0 . 50 . Ticket prices were considered high for the day and steel pillars supporting the roof occasionally blocked fans ' views of the field . Two thousand bleachers were situated along the left field side , tickets were sold for a maximum of $ 1 . When winning streaks would attract high attendance to games , fans were permitted to sit on the grass in right field , provided they would agree to allow a player to catch any ball hit in the area . The lowest season of attendance came in 1914 when 139 , 620 people attended games ; the highest at the stadium came in 1960 , when 1 , 705 , 828 people watched the Pirates play . On September 23 , 1956 , the stadium ' s largest crowd , 44 , 932 , gathered to see the home team play the Brooklyn Dodgers . The game was cut short in the top of the ninth inning , after a rain delay forced it past the Pennsylvania Sunday curfew . The Dodgers won the game 8 – 2 the following day . At 200 people , June 10 , 1938 marked the smallest crowd to ever attend a Pirates game . On September 30 , 1962 , a crowd of 40 , 916 people saw the Steelers defeated by the New York Giants , at the Steelers ' highest - attended game at the stadium . Closing and demolition . Though Forbes Field was praised upon its opening , it began to show its age after 60 years of use . The park was the second oldest baseball field in the league at the time — younger than only Shibe Park in Philadelphia . The location of the park , which was initially criticized for not being developed , grew into a " bustling business district " which led to a lack of parking space . One sportswriter wrote that " The House of Thrills " had become " as joyless as a prison exercise yard " . Following a plan to expand their adjacent campus , the University of Pittsburgh purchased Forbes Field in 1958 , with an agreement to lease the stadium to the Pirates until a replacement could be built . A proposal for a new sports stadium in Pittsburgh was first made in 1948 , but plans did not attract much attention until the late 1950s . Construction began on Three Rivers Stadium on April 25 , 1968 . The Pittsburgh Pirates and the Chicago Cubs played a double - header on June 28 , 1970 . Pittsburgh won the first game 3 – 2 . In the later game Al Oliver hit the last home run in the park , and Matty Alou drove in two runs as the Pirates closed the 62 - year old stadium with a 4 – 1 victory . The 40 , 918 spectators in attendance stood and cheered as Bill Mazeroski retired Willie Smith for the final out at the stadium . Pirates Hall of Famer Roberto Clemente played fifteen seasons at Forbes Field . He was emotional during the last game saying , " I spent half my life there . " The abandoned structure suffered two separate fires that damaged the park , on December 24 , 1970 and July 17 , 1971 . Eleven days after the second fire , demolition began , and the site was cleared for use by the University of Pittsburgh . Memorials . In 1955 , a statue of Honus Wagner was dedicated in Schenley Plaza adjacent to Forbes Field . Several thousand fans attended the dedication as well as Wagner himself . His failing health caused him to never leave his open convertible which he arrived in . The 1800 pound statue was moved to Three River Stadium in 1970 . Today , the statue stands at the home plate entrance of PNC Park . The portion of the left field wall over which Bill Mazeroski hit his walk - off home run to end the 1960 World Series , between the scoreboard and the " 406 FT " sign , no longer stands at its original location . A portion of that wall , including the distance marker , had been sliced off and moved to the Allegheny Club at Three Rivers Stadium . Before the Three Rivers demolition , the section of the wall was salvaged , and in 2009 it was restored and placed on the Riverwalk outside of PNC Park . Meanwhile , the original location of that wall is outlined by bricks extending from the left - center field wall across Roberto Clemente Drive and into the sidewalk . A plaque embedded in the sidewalk marks the spot where Mazeroski ' s home run cleared the wall . The left - center and center field brick wall with " 457 FT " and " 436 FT " painted on it still stands at its original location , along with the stadium ' s flagpole , adjacent to the University of Pittsburgh ' s Mervis and Posvar Hall s . Despite not technically being the correct section of wall where Mazeroski ' s famous home run cleared , it is often locally referred to as " Mazeroski ' s Wall . " This portion of the wall remained after Forbes Field was torn down , and was refurbished in 2006 in time for the All - Star Game hosted in Pittsburgh . In addition , a wooden replica of an entrance to the stadium , including a ticket window and players entrance , was constructed and placed near the remaining wall in 2006 . The home plate used in the stadium ' s final game remains preserved in the University of Pittsburgh ' s Posvar Hall . However , its location has been altered ; author John McCollister wrote , " Had architects placed home plate in its precise spot about half of the Pirates fans could not view it . The reason : it would have to be on display in the fifth stall of the ladies ' restroom . " However , the original location of the home plate has been more recently determined by others to be approximately 81 feet away from its current display , just inside the GSPIA / Economics Library , and not in a restroom as has been popularly believed . A ceremony is held each October 13 at the outfield wall in Oakland to listen to a taped broadcast of the final game of the 1960 World Series . The tradition was started by Squirrel Hill resident Saul Finkelstein , who at 1 : 05 pm on October 13 , 1985 , sat alone at the base of the flagpole and listened to the NBC radio broadcast of Chuck Thompson and Jack Quinlan . Finkelstein continued the tradition for eight more years , until word spread and other people began attending in 1993 . On October 13 , 2000 — the game ' s 40th anniversary — over 600 people attended to listen to the broadcast , including Mazeroski himself . For the 50th anniversary , on October 13 , 2010 , a plaque honoring Mazeroski was dedicated and more than 1 , 000 attended the broadcast , including Mazeroski and several other former Pirates . Events . Baseball . In 1909 , Forbes Field ' s opening season , the Pirates beat the Detroit Tigers in the World Series . It would be the only meeting of eventual Hall of Famers Honus Wagner and Ty Cobb . On October 2 , 1920 , Forbes Field hosted the last triple - header in MLB history . On August 5 , 1921 , Forbes Field was the site of the first live radio broadcast of a Major League Baseball game in the United States . Harold W . Arlin announced the play - by - play action between the Pittsburgh Pirates and the Philadelphia Phillies over KDKA from a box seat next to the first - base dugout . Regular broadcasts began in 1938 by A . K . “ Rosey ” Roswell , a local humorist and friend of owner Bill Benswanger . Roswell is quoted as describing his broadcasting with , “ It ’ s not just play - by - play that matters . It ’ s what you say in between the pitches that counts . ” His style influenced junior partner Bob Prince who began broadcasting in 1948 . Roswell broadcast games at Forbes Field until his death in 1955 . In 1925 , the Pirates became the first team to come back from a three game to one deficit to defeat the Washington Senators and win the World Series . Pittsburgh ' s third and final World Series championship while they played at Forbes Field came in 1960 . Bill Mazeroski hit the first home run to end a World Series and as of 2010 , the only walk - off home run in World Series Game Seven history . Two unassisted triple play s were turned at Forbes Field . The first took place on May 7 , 1925 , when Pittsburgh ' s Glenn Wright achieved the feat . Two seasons later , in 1927 , Jimmy Cooney — who had been a victim of the first triple play — also acquired three outs by himself . On May 25 , 1935 , at Forbes Field , Babe Ruth hit the last three home runs of his career as his Boston Braves lost to the Pirates , 11 - 7 . His last home run cleared the right field stands roofline , making him the first player to ever do so . Most of the game - action scenes from the 1951 film " Angels in the Outfield " were filmed at the stadium . On May 28 , 1956 , Dale Long of the Pirates took what one author has stated was the first - ever curtain call in baseball history , after hitting home runs in eight consecutive games caused fans to cheer for five minutes . The Homestead Grays of the Negro leagues played all home games at Forbes Field from 1922 to 1939 . Grays owner Cumberland Posey became friends with Dreyfuss , who rarely missed a Grays game . In 1930 , Josh Gibson made his premiere for the Grays at Forbes Field . Also in 1930 , the Grays and the Kansas City Monarchs played the first baseball game at night in Pittsburgh on July 18 , 1930 . A crowd of over 15 , 000 was expected . Floodlights were installed the day before the game after they were transported from Cleveland , where the Grays and Monarchs had played on July 16 . Six members of the Grays ' 1936 team have been inducted into the Baseball Hall of Fame . Beginning in 1937 , the Grays won nine consecutive Negro National League championships . The University of Pittsburgh ' s baseball team would also often use Forbes Field for home games . Football . The University of Pittsburgh ' s football team moved from Exposition Park into Forbes Field upon its opening in 1909 and played there until 1924 when it moved into the larger Pitt Stadium only a few blocks away . In their first game at Forbes Field on October 16 , 1909 , the Panthers defeated Bucknell University 18 – 6 . In 1910 , Pitt ' s second year at Forbes Field , the Panthers went undefeated without allowing a single point . The Panthers had several successful seasons while playing at Forbes Field , including five in which they went undefeated and were awarded national championship titles in 1910 , 1915 , 1916 , 1917 , and 1918 . During their years at Forbes Field , Pitt ' s teams were led by Hall of Fame coaches Joe Thompson , Glenn " Pop " Warner and Jock Sutherland . Forbes Field was the site of yet another broadcasting first when on October 8 , 1921 , Harold W . Arlin announced live play - by - play action of the Pitt - West Virginia football game on radio station KDKA , the first live radio broadcast of a college football game in the United States . Pittsburgh native , Art Rooney founded his NFL team under the name the Pittsburgh Pirates , on July 8 , 1933 , for $ 2 , 500 ( $ in present - day terms ) . The franchise ' s first game , against the New York Giants , was held on September 20 , 1933 , at Forbes Field . The Giants won the game 23 – 2 in front of 25 , 000 people . Rooney wrote of the game , " The Giants won . Our team looks terrible . The fans didn ' t get their money ' s worth . " The Pirates would rebound to gain their first ever franchise victory a week later at Forbes Field , against the Chicago Cardinals . The NFL ' s Pirates were renamed the Steelers in 1940 , and otherwise struggled during much of their three - decades of tenancy at Forbes . The club achieved its first winning record in 1942 ; its tenth season of existence . On November 30 , 1952 , the Steelers met the New York Giants at Forbes Field for a snowy afternoon game . Pittsburgh entered the game with a 3 – 6 record , but went on to set multiple team records , including scoring nine touchdowns , to win the game 63 – 7 . Excited by their team ' s play , the 15 , 140 spectators ran onto the field and began to tear the field goal posts out of the ground . The University of Pittsburgh ' s acquisition of Forbes Field in 1958 gave the Steelers some options , and they began transferring some of their home games to the much larger Pitt Stadium that year . The Steelers played their final game at Forbes Field on December 1 , 1963 . The franchise would move to Pitt Stadium exclusively the following season . Boxing and other events . Boxing bouts were held at Forbes Field from the 1910s to the 1950s , attracting crowds of over 15 , 000 people .

Pittsburgh native Billy Conn defended his light heavyweight title against Melio Bettina , whom he had beaten months earlier . Conn won the bout by decision in 15 rounds . Two years later , on June 18 , 1941 , Conn fought Joe Louis at New York City ' s Polo Grounds , in an attempt to become the world heavyweight champion . The Pirates and the New York Giants , who were playing at Forbes Field , were called into their dugouts while the 24 , 738 fans in attendance listened to the radio broadcast of the hour - long bout .
