Question: When is the opening day of the league in which the team with the most games in the series after which the MLB MVP is awarded plays?

<P0-S0> 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. <P0-S1> 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> <P1-S0> as of 2018, nl players have won the award 27 times (including one award shared by two players), and american league (al) players have won 30 times. <P1-S1> baltimore orioles players have won the most awards for a single franchise (with six); players from the cincinnati reds, los angeles dodgers and san francisco giants are tied for the most in the nl with five each. <P1-S2> five players have won the award twice: willie mays (1963, 1968), steve garvey (1974, 1978), gary carter (1981, 1984), cal ripken, jr. (1991, 2001), and mike trout (2014, 2015). <P1-S3> the award has been shared by multiple players once; bill madlock and jon matlack shared the award in 1975. two players have won the award for a game in which their league lost: brooks robinson in 1966 and carl yastrzemski in 1970. one pair of awardees were father and son (ken griffey sr. and ken griffey jr.), and another were brothers (roberto alomar and sandy alomar, jr.). <P1-S4> mike trout of the los angeles angels of anaheim became the first player ever to win the mvp award in back - to - back years in the 86 - year history of the mlb all - star game when he accomplished the feat in both 2014 and 2015. alex bregman of the houston astros is the most recent mlb all - star game mvp, winning the award in 2018. only six players have won the mvp award in the only all - star game in which they appeared; lamarr hoyt, bo jackson, j.d. <P1-S5> drew, melky cabrera, eric hosmer, and alex bregman. <SEP> <P2-S0> in major league baseball (mlb), the wild - card teams are the two teams in each of the two leagues (american and national) that have qualified for the postseason despite failing to win their division. <P2-S1> both teams in each league possess the two best winning percentages in their respective league after the three division winners. <P2-S2> the wild card was first instituted in mlb in 1994, with one wild - card team per league advancing to the division series in the postseason to face a division winner. <P2-S3> in 2012, the system was modified to add a second wild - card team per league and pit each league's wild - card teams against each other in a play - in game -- the mlb wild - card game -- the winner of which would then advance to the division series and play the team with the best record. <P2-S4> this system ensures that the team with the second - best record in each league, after the three division winners and the team with the first - best record in the league that is a non-division winner, will also get a postseason berth, even if it is n't a division champion. <SEP> <P3-S0> The New York Yankees are an American professional baseball team based in the New York City borough of the Bronx. <P3-S1> 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. <P3-S2> In the season, the club began play in the AL as the Baltimore Orioles (no relation to the modern Baltimore Orioles). <P3-S3> 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. <P3-S4> The Yankees compete in Major League Baseball (MLB) as a member club of the American League (AL) East division. <P3-S5> The Highlanders were officially renamed the Yankees in . <SEP> <P4-S0> The BBWAA began by polling three writers in each league city in 1938, reducing that number to two per league city in 1961. <P4-S1> The BBWAA does not offer a clear - cut definition of what ``most valuable ''means, instead leaving the judgment to the individual voters. <P4-S2> MVP voting takes place before the postseason, but the results are not announced until after the World Series. <SEP> <P5-S0> 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). <P5-S1> 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. <P5-S2> Similarly, most teams opened the 2012 season on Thursday (April 5) or Friday (April 6). <P5-S3> However, subsequent seasons through 2017 returned to Monday openers for most teams.
