Question: When does regular season start in the league where a team has played the most games in the competition where they give out the MLB MVP award after?

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 play the pearson cup exhibition game; 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. <SEP> In the American League, the New York Yankees have played in 40 World Series and won 27, the Philadelphia / Kansas City / Oakland Athletics have played in 14 and won 9, and the Boston Red Sox have played in 12 and won 8, including the first World Series. In the National League, the St. Louis Cardinals have appeared in 19 and won 11, the New York / San Francisco Giants have played in 20 and won 8, the Brooklyn / Los Angeles Dodgers have appeared in 19 and won 6, and the Cincinnati Reds have appeared in 9 and won 5. <SEP> The Postseason will begin on October 2. The 2018 World Series is set to begin on October 23, and a potential Game 7 is scheduled on October 31. The 2018 Major League Baseball season began on March 29, 2018, and is scheduled to end on September 30. <SEP> major league baseball had most of its teams open the 2011 season on a thursday (march 31) or friday (april 1) rather than the traditional monday, in order to prevent the world series from extending into november. similarly, most teams opened the 2012 season on thursday (april 5) or friday (april 6). however, subsequent seasons through 2017 returned to monday openers for most teams. for the 2018 season, all 30 teams were scheduled to open the season on thursday, march 29 (the earliest domestic start for a regular season in mlb history, and the first time since 1968 that all major league teams were scheduled to start the season on the same day, although two games were subsequently rained out and postponed to friday, march 30). <SEP> The New York Yankees are an American professional baseball team based in the New York City borough of the Bronx. The Yankees compete in Major League Baseball (MLB) as a member club of the American League (AL) East division. They are one of two major league clubs based in New York City; the other club is the National League (NL)'s New York Mets. In the season, the club began play in the AL as the Baltimore Orioles (no relation to the modern Baltimore Orioles). Frank Farrell and Bill Devery purchased the franchise that had ceased operations and moved it to New York City, renaming the club the New York Highlanders. The Highlanders were officially renamed the Yankees in . <SEP> The BBWAA began by polling three writers in each league city in 1938, reducing that number to two per league city in 1961. MVP voting takes place before the postseason, but the results are not announced until after the World Series. The BBWAA does not offer a clear - cut definition of what ``most valuable ''means, instead leaving the judgment to the individual voters.
