 The Mets qualified for the postseason by winning the National League ( NL ) East , their sixth division title . They faced the Los Angeles Dodgers in the 2015 NL Division Series , winning in five games . In the 2015 NLCS , Daniel Murphy led the team by hitting home runs in each game of the four @-@ game sweep of the Chicago Cubs . By winning the NLCS , the Mets ensured that they have the most World Series appearances by an expansion franchise with five . In addition , the Mets have made World Series appearances in all but one of their six decades of existence , not appearing in any that were played during the 1990s . This was the first World Series appearance for Mets ' manager Terry Collins .

 Ongoing negotiations through March yielded an agreement on March 7 , 1999 , over the objections of the State Department .

 The game was necessary after both teams finished the season with identical win – loss records of 96 – 66 . Some described the Mets as collapsing late in the season while the race between the Reds and their division rival Houston Astros was close enough to create the possibility of a three @-@ way tie . The Reds won a coin flip late in the season which , by rule at the time , awarded them home field for the game . Upon winning , the Mets advanced to NL Division Series ( NLDS ) where they defeated the Arizona Diamondbacks , three @-@ games @-@ to @-@ one . They then advanced to the NL Championship Series ( NLCS ) but were defeated by the Atlanta Braves in six games , bringing an end to the Mets ' season . In baseball statistics , the tie @-@ breaker counted as the 163rd regular season game by both teams , with all events in the game added to regular season statistics .
