Context: The 2014 Major League Baseball All-Star Game was the 85th edition of the Major League Baseball All-Star Game, held at Target Field in Minneapolis, Minnesota, the home of the Minnesota Twins.  This was the third All-Star Game played in the Twin Cities; Metropolitan Stadium hosted the game in 1965, while the Hubert H. Humphrey Metrodome hosted the game in 1985.  It was televised in the United States on Fox as part of a new eight-year deal.  In preparation for the game the Twin Cities' transit company, MetroTransit, completed the new METRO Green Line light-rail between downtown Minneapolis and downtown Saint Paul, and began service on June 14, 2014. The 2017 Major League Baseball All-Star Game was the 88th edition of the Major League Baseball All Star Game.  The game was hosted by the Miami Marlins and was played at Marlins Park on July 11, 2017.  It was televised nationally by Fox.  The game was the first since 2002 whose outcome did not determine home-field advantage for the World Series; instead, the team with the better regular-season record will have home-field advantage.  The Marlins were announced as the hosts on February 10, 2015, by Major League Baseball Commissioner Rob Manfred; the game was the Marlins' first time hosting, leaving the Tampa Bay Rays as the only MLB franchise not to have hosted an All-Star game.

The American League All-Stars defeated the National League All-Stars by a score of 4–2 to win home field advantage for the 2016 World Series (which went to the Cleveland Indians).  This was also the last time home-field advantage for the World Series was determined by the outcome of the All-Star Game.

This was the seventh year in which the All-Star Game determined home field advantage in the World Series, with the American League winning all seven games up to and including 2009 under this format.  After the game, the National League lead, 40–38–2, but had not won since 1996.  Fox televised the contest, with Joe Buck and Tim McCarver in the booth for the game broadcast, joined at the bottom of the 2nd inning by President Barack Obama.
