national teams are selected from NHL and other pro players, and college teams would be overmatched against those teams even if they were allowed to play them. However, the national under-18 teams are made up of amateurs, allowing college squads to play them.) Baseball The Major League Baseball's preseason is also known as spring training. All MLB teams maintain a spring-training base in Arizona or Florida. The teams in Arizona make up the Cactus League, while the teams in Florida play in the Grapefruit League. Each team plays about 30 preseason games against other MLB teams. They may also play exhibitions against a local college team or a minor-league team from their farm system. Some days feature the team playing two games with two different rosters evenly divided up, which are known as "split-squad" games. Several MLB teams used to play regular exhibition games during the year against nearby teams in the other major league, but regular-season interleague play has made such games unnecessary. The two Canadian MLB teams, the Toronto Blue Jays of the American League and the Montreal Expos of the National League, met annually to contest the Pearson Cup; this tradition ended when the Expos moved to Washington DC for the 2005 season. Similarly, the New York Yankees played in the Mayor's Trophy Game against various local rivals from 1946 to 1983. It also used to be commonplace to have a team play an exhibition against Minor League affiliates during the regular season, but worries of injuries to players, along with travel issues, have made this very rare. Exhibitions between inter-city teams in different leagues, like Chicago's Crosstown Classic and New York's Subway Series which used to be played solely as exhibitions for bragging rights are now blended into interleague play. The annual MLB All-Star Game, played in July between players from AL teams and players from NL teams, had long been considered an exhibition match, though between 2003 and 2016 this status was questioned because the league whose team won the All-Star game has been awarded home field advantage for the upcoming World Series (prior to 2003 the leagues alternated which one of them had home field advantage; starting in 2017 the team with the better regular season record would be given home field advantage). Another exhibition game, the Hall of Fame Game/Classic which was played in Cooperstown, New York on the weekend of inductions to
