Question: When was the spring training home of the team sharing a field with the Raiders built?

full_context: Document 1: History of the Oakland Athletics: The history of the Athletics Major League Baseball franchise spans the period from 1901 to the present day, having begun in Philadelphia before moving to Kansas City in 1955 and then to its current home in Oakland, California, in 1968.
Document 2: 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 4: 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 5: RingCentral Coliseum: The Oakland -- Alameda County Coliseum, often referred to as the Oakland Coliseum, is a multi-purpose stadium in Oakland, California, United States, which is home to both the Oakland Athletics of Major League Baseball (MLB) and the Oakland Raiders of the National Football League (NFL). It opened in 1966 and is the only remaining stadium in the United States that is shared by professional football and baseball teams. The Coliseum was also home to some games of the San Jose Earthquakes of Major League Soccer in 2008 -- 2009 and hosted games at the 2009 CONCACAF Gold Cup. The Oakland -- Alameda County Coliseum complex consists of the stadium and the neighboring Oracle Arena.
Document 6: 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: Oakland Raiders relocation to Las Vegas: The Oakland Raiders relocation to Las Vegas was a successful effort by the owner of the Oakland Raiders (Mark Davis) to relocate the American football club from its current and longtime home of Oakland, California to Las Vegas, Nevada. The team is scheduled to begin play as the Las Vegas Raiders for the 2020 National Football League (NFL) season (although a move to Las Vegas could happen as soon as 2019 with Sam Boyd Stadium), playing home games at the Las Vegas Stadium. NFL team owners voted 31 -- 1 to approve the move, which was announced at the annual league meetings in Phoenix, Arizona on March 27, 2017. The Raiders became the third NFL franchise to relocate in the 2010s, following the Rams' move from St. Louis, Missouri to Los Angeles, California on January 12, 2016, and the Chargers' move from San Diego, California to Los Angeles on January 12, 2017. The Raiders' move to Las Vegas comes after years of failed efforts to renovate or replace the Oakland -- Alameda County Coliseum, which has been rated by multiple sources as one of the worst stadiums in the NFL.
Document 8: 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 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: Chase Center: Chase Center is a multi-purpose arena under construction in the Mission Bay neighborhood of San Francisco. The building will mainly be used for basketball, and is planned to become the new home venue for the National Basketball Association (NBA)'s Golden State Warriors. The Warriors, who have been located in the San Francisco Bay Area since 1962, have played their home games at Oracle Arena in Oakland since 1971. The arena is scheduled to open to the public before the start of the 2019 -- 20 NBA season, with groundbreaking having occurred during the 2016 -- 17 NBA season.
Document 15: 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.
