Context: The 1997 Atlanta Braves season marked the franchise's 32nd season in Atlanta and 127th overall.  The Braves won their sixth consecutive division title, taking the National League East title by 9 games over the second place Florida Marlins.  However, the Marlins would later defeat the Braves in the 1997 National League Championship Series.  1997 was the first year that the Braves played their home games in Turner Field, which originally served as a venue for the 1996 Summer Olympics. Turner Field was a baseball park located in Atlanta, Georgia.  From 1997 to 2016, it served as the home ballpark to the Atlanta Braves of Major League Baseball (MLB).  Originally built as Centennial Olympic Stadium in 1996 to serve as the centerpiece of the 1996 Summer Olympics, the stadium was converted into a baseball park to serve as the new home of the team.  The Braves moved less than one block from Atlanta–Fulton County Stadium, which served as their home ballpark for 31 seasons from 1966 to 1996. The Atlanta Braves are an American professional baseball franchise based in the Atlanta metropolitan area.  The franchise competes in Major League Baseball (MLB) as a member of the National League (NL) East division.  The Braves played home games at Atlanta–Fulton County Stadium from 1966 to 1996, and Turner Field from 1997 to 2016.  Since 2017, their home stadium has been SunTrust Park, a new stadium 10 miles (16 km) northwest of downtown Atlanta in the Cumberland neighborhood of Cobb County.  The Braves play spring training games in Lake Buena Vista, Florida.  In January 2017, the Braves announced a formal agreement to move their spring training home to North Port, Florida. The 2012 Atlanta Braves season was the Braves' 16th season of home games at Turner Field, 47th season in Atlanta, and 142nd season overall.  After a late season collapse in 2011 kept the Braves from the playoffs, the team returned to the postseason for the second time in three seasons as a Wild Card team, with a record of 94-68.  They lost to the St. Louis Cardinals in the one-game Wild Card Playoff. On May 18, 2004, Randy Johnson, who was a pitcher for the Major League Baseball (MLB) Arizona Diamondbacks, pitched a perfect game against the Atlanta Braves.  The game took place at Turner Field in Atlanta in front of a crowd of 23,381 people.  Johnson, who was 40 at the time, was the oldest pitcher in MLB history to throw a perfect game, surpassing Cy Young who was 37 when he threw his perfect game in 1904.  The perfect game was the 17th in baseball history, the predecessor being David Cone in 1999 and the seventh in National League history, the predecessor being Dennis Martínez in 1991. The 2017 Atlanta Braves season was the Braves' 52nd season in Atlanta and 147th overall.  This is the Braves' first season at SunTrust Park, after playing the previous 20 seasons at Turner Field.  The Brave began the season on April 3 at Citi Field against the New York Mets and will finish the season on October 1 against the Miami Marlins at Marlins Park.  On September 22, 2017, the Braves were eliminated from postseason play. Randall Enrique Delgado (born February 9, 1990) is a Panamanian professional baseball pitcher for the Arizona Diamondbacks of Major League Baseball.  Delgado previously played for the Atlanta Braves. SunTrust Park is a baseball park located in the Atlanta metropolitan area 10 miles (16 km) northwest of downtown Atlanta in the Cumberland neighborhood of Cobb County.  It is the home ballpark for the Atlanta Braves, the city's Major League Baseball (MLB) franchise.  On November 11, 2013, the Braves announced that the franchise would leave Turner Field for a new park after the 2016 season.  The Braves have played their home games at SunTrust Park since April 2017. The 2014 Atlanta Braves season was the Braves' 18th season of home games at Turner Field, 49th season in Atlanta, and 144th season overall.  Before September, the Braves had two winning months and three non-winning months that they played, and briefly reached first place in their division.  The team's performance declined in September, as the team lost 16 out of the 20 games they played that month.  They finished tied in 2nd place with a 79–83 record, 17 games back in second place in the division, and failed to make the playoffs. The 2000 Major League Baseball All-Star Game was the 71st playing of the midsummer classic between the all-stars of the American League (AL) and National League (NL), the two leagues comprising Major League Baseball.  The game was held on July 11, 2000 at Turner Field in Atlanta, Georgia, home of the Atlanta Braves of the National League.  The Florida Marlins were originally awarded the 2000 All-Star game in July 1995, but then-NL president Len Coleman took it away in November 1998 and gave it to the Atlanta Braves, saying the league wanted the game in new ballparks.  The result of the game was the American League defeating the National League by a score of 6–3.
