For the 1888 season, Gore played in just 64 of the team's 138 games. O'Rourke had reclaimed a starting position, this time in left field, while Gore split his playing time between center and left field. Gore's popularity waned early into the season, so much so that on May 3, New York fans screamed at on-field captain Ewing to play Mike Slattery instead. Gore had already taken his position in left field, but Ewing made the change to Slattery before the game started. New York finished the season as the National League champions, and met the St. Louis Browns in the World Series. Gore appeared in three of the eleven games that were played during this post-season exhibition. New York was declared the victor, winning six games, and Gore contributed five hits in eleven at-bats for a .455 batting average during the series.
