Gore joined a New York Giants team that had a roster that contained no less than six future Baseball Hall of Famers: John Montgomery Ward, Roger Connor, Buck Ewing, Tim Keefe, Mickey Welch, and Jim O'Rourke.
Gore took his usual position in center field, replacing O'Rourke, who was the starter the previous season.
Gore played well that first season in New York, batting .290 and scoring 95 runs, but the team finished in fourth place in the National League.

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.

Gore regained his starting position in center field for the 1889 season, and his play improved over his 1888 performance.
He batted .305, scored 132 runs, and hit seven home runs in 120 games played, although he did commit 41 errors in center field, which led the league.
The Giants again finished the season as the champions of the NL, and met the Brooklyn Bridegrooms in the 1889 World Series after the season.
New York was again declared the victor after winning six of the nine games exhibition games played.
Gore played in five of these games, collecting seven hits in 21 at-bats for a .333 batting average.
