<P> This rule is subject to debate, with various writers feeling that home - field advantage should be decided based on the regular season records of the participants, not on an exhibition game played several months earlier . Some writers especially questioned the integrity of this rule after the 2014 All - Star Game, when St. Louis Cardinals pitcher Adam Wainwright suggested that he intentionally gave Derek Jeter some easy pitches to hit in the New York Yankees' shortstop's final All - Star appearance before he retired at the end of that season . </P> <P> As Bob Ryan of The Boston Globe wrote in July 2015 about the rule: </P> <P> "So now we have a game that's not real baseball determining which league hosts Games 1, 2, 6, and 7 in the World Series . It's not a game if pitchers throw one inning . It's not a game if managers try to get everyone on a bloated roster into the game . It's not a game if every franchise, no matter how wretched, has to put a player on the team...If the game is going to count, tell the managers to channel their inner Connie Mack and go for it ." </P> <P> However, within the last seven seasons, home - field advantage, in terms of deciding World Series games, has not necessarily worked for teams of said games . Since 2014, the home team has not won the deciding game of a World Series . </P>
