Question: What year saw the construction of the spring training home of the team that Henry Mercedes played for?

full_context: Document 1: 2002 Oakland Athletics season: The new - look Athletics experienced a bumpy start to the 2002 regular season. The team followed a respectable 15 - 10 start with an abysmal 5 - 16 run; at the end of their slump, on May 23, the team's record stood at 20 - 26. From this point forward, the Athletics' fortunes improved significantly. In a prelude to the team's famous late - season winning streak, the Athletics went 16 - 1 from June 6 to June 24. The surge propelled the club within two games of first place. For now, this was as close as the team would get; a prolonged funk saw the A's play roughly. 500 baseball for the next month - and - a-half. This period ended with an unremarkable 2 - 1 loss to the Toronto Blue Jays on August 12.
Document 2: Gerónimo Berroa: After the season, he signed as a free agent with the Oakland Athletics, and had his best years with that team. Berroa's best season was 1996 when he hit 36 home runs with 106 RBIs for the Athletics. He spent the next three seasons with the Baltimore Orioles, Cleveland Indians, Detroit Tigers, Blue Jays, and Los Angeles Dodgers.
Document 3: Highland Park Stadium: Highland Park Stadium was built as the home of the Kokomo Giants in 1955, and then Kokomo Dodgers from 1956 to 1961. The stadium generally holds 3,000 people, but findable records show 7,000 people attended a game in 1961. The stadium received its first renovation in 1985, which added most of the bleachers that are there today. 1985 was also when it hosted a minor league world series game. The stadium is due for another renovation in 2014; however, it is unclear what exactly will be redone with the stadium. Currently the stadium is just used for local games such as high school baseball teams, and the mayor, Greg Goodnight, has stated he doesn't foresee any upcoming teams in Kokomo, although he would like to see one.
Document 4: Alex Rodriguez: In 2005, Rodriguez hit. 321, leading the American League with 124 runs and 48 HR while driving in 130 runs. He became the first Yankee to win the American League home run title since Reggie Jackson (41) in 1980. He also became one of only two players in Major League history to compile at least 35 home runs, 100 runs and 100 RBIs in eight consecutive seasons (Jimmie Foxx accomplished the feat in nine straight seasons from 1932 to 1940). Rodriguez established the franchise record for most home runs in a single season by a right - handed batter (broke Joe DiMaggio's mark of 46 in 1937). His 47 HR from the third base position are a single - season American League record. Rodriguez hit 26 home runs at Yankee Stadium in 2005, establishing the single - season club record for right - handed batters (previously held by DiMaggio in 1937 and Gary Sheffield in 2004). On June 8, at 29 years, 316 days old, he became the youngest player in MLB history to reach the 400 HR mark. 2005 also marked the tenth straight season that Rodriguez scored at least 100 runs. On defense, however, he had the lowest range factor in the league at third for the second straight season (2.62).
Document 5: Chicago Cubs: The former location in Mesa is actually the second HoHoKam Park; the first was built in 1976 as the spring-training home of the Oakland Athletics who left the park in 1979. Apart from HoHoKam Park and Sloan Park the Cubs also have another Mesa training facility called Fitch Park, this complex provides 25,000 square feet (2,300 m2) of team facilities, including major league clubhouse, four practice fields, one practice infield, enclosed batting tunnels, batting cages, a maintenance facility, and administrative offices for the Cubs.

Document 7: Chicago Cubs: In addition to Mesa, the club has held spring training in Hot Springs, Arkansas (1886, 1896–1900), (1909–1910) New Orleans (1870, 1907, 1911–1912); Champaign, Illinois (1901–02, 1906); Los Angeles (1903–04, 1948–1949), Santa Monica, California (1905); French Lick, Indiana (1908, 1943–1945); Tampa, Florida (1913–1916); Pasadena, California (1917–1921); Santa Catalina Island, California (1922–1942, 1946–1947, 1950–1951); Rendezvous Park in Mesa (1952–1965); Blair Field in Long Beach, California (1966); and Scottsdale, Arizona (1967–1978).
Document 8: Bob Allison: A gifted all-around athlete, Allison attended the University of Kansas for two years and was a star outfielder on the baseball team and fullback on the football team. In his Major League career, he hit 30 or more home runs three times and 20 or more in eight different seasons. Although he struck out often like many sluggers, reaching the century mark in strikeouts in five seasons, he received more than his share of walks and despite a mediocre career .255 batting average, Allison finished with a lifetime on-base percentage (OBP) of .358 and he finished in the top 10 in OBP in four seasons. Allison wasn't an especially fast player, but he was among the most feared base-runners of his time in hustling out numerous doubles and triples – leading the league in triples in 1959 (with 9) and finishing in the top 10 twice in doubles (1960 & 1964) and four times in triples (1959, 1962, 1967, and 1968).
Document 9: Bob Henley: Henley would appear in 41 games, starting 30 at catcher, for the 1998 Expos, as he and Mike Hubbard backed up regular Chris Widger. He amassed 35 hits and 11 walks in 132 plate appearances, batting .304 and collecting three homers (off Pedro Astacio, Kirt Ojala and Bobby Jones) and eight doubles. On September 25, his penultimate appearance of the season, Henley went 4-for-4 with two doubles and three runs batted in against the St. Louis Cardinals.
Document 10: Chicago Cubs: The curious location on Catalina Island stemmed from Cubs owner William Wrigley Jr.'s then-majority interest in the island in 1919. Wrigley constructed a ballpark on the island to house the Cubs in spring training: it was built to the same dimensions as Wrigley Field. (The ballpark is long gone, but a clubhouse built by Wrigley to house the Cubs exists as the Catalina County Club.) However, by 1951 the team chose to leave Catalina Island and spring training was shifted to Mesa, Arizona. The Cubs' 30-year association with Catalina is chronicled in the book, The Cubs on Catalina, by Jim Vitti . . . which was named International 'Book of the Year' by The Sporting News.
Document 11: Henry Mercedes: After making an impressive Major League debut with the Oakland Athletics at the end of the 1992 season, going 4 for 5 (.800) on the season with a triple, he again played for the Athletics in 1993, followed by stints with the Kansas City Royals from 1995 to 1996 and the Texas Rangers in 1997.
Document 12: Chicago Cubs: The confusion may stem from the fact that Major League Baseball did decide that, should the Cubs make it to the World Series, the American League winner would have home field advantage unless the Cubs hosted home games at an alternate site since the Cubs home field of Wrigley Field did not yet have lights. Rumor was the Cubs could hold home games across town at Comiskey Park, home of the American League's Chicago White Sox. Rather than hold any games in the cross town rival Sox Park, the Cubs made arrangements with the August A. Busch, owner of the St. Louis Cardinals, to use Busch Stadium in St. Louis as the Cubs "home field" for the World Series. This was approved by Major League Baseball and would have enabled the Cubs to host games 1 and 2, along with games 6 and 7 if necessary. At the time home field advantage was rotated between each league. Odd numbered years the AL had home field advantage. Even numbered years the NL had home field advantage. In the 1982 World Series the St. Louis Cardinals of the NL had home field advantage. In the 1983 World Series the Baltimore Orioles of the AL had home field advantage.
Document 13: Sloan Park: Sloan Park is an American baseball park in Mesa, Arizona which opened in 2014. The primary operator is the Chicago Cubs and the ballpark serves as their spring training home and is also the home of the Arizona League Cubs of the Arizona League and the Mesa Solar Sox of the Arizona Fall League. Sloan Park was built and paid for by residents of the City of Mesa, approved by ballot measure. It was primarily built to house spring training operations for the Chicago Cubs, who had previously played at nearby Hohokam Stadium. The stadium design was led by Populous. The dimensions of the playing surface closely match those of the Cubs' regular home stadium, Wrigley Field.
Document 14: Soldier Field: Soldier Field was used as a site for many sporting events and exhibitions. The Chicago Cardinals used it as their home field for their final season in Chicago in 1959. A dozen years later in September 1971, the Chicago Bears moved in, originally with a three - year commitment. They previously played at Wrigley Field, best known as the home of the Chicago Cubs baseball team, but were forced to move to a larger venue due to post-AFL -- NFL merger policies requiring that stadium capacities seat over 50,000 spectators. They had intended to build a stadium in Arlington Heights. In 1978, the Bears and the Chicago Park District agreed to a 20 - year lease and renovation of the stadium. Both parties pooled their resources for the renovation. The playing surface was AstroTurf from 1971 through 1987, replaced with natural grass in 1988.
Document 15: Gordon Massa: But Massa chose professional baseball as his destination and signed with the Cubs on June 24, 1957. Three months later, after prepping with the Des Moines Bruins of the Class A Western League, Massa made his MLB debut, starting at catcher and notching two hits, both singles, in four at bats with one run batted in against Hal Jeffcoat of the Cincinnati Redlegs. All told, Massa collected seven hits in 15 at-bats with three RBI during his first trial with the Cubs. The following year, he was sent to the Class B Illinois–Indiana–Iowa League for further minor league seasoning, and he batted .316 to earn his second late-season call-up to the Cubs. He went hitless in two at-bats.
