Cooley played more regularly in 1895 and averaged 4.2 at bats per game throughout the season. One of the most successful batters on the team, he had the highest batting average at .342 and led the Cardinals in hits, triples, runs scored and total bases. His slugging (.466) and on-base plus slugging (.851) percentages remained the highest of his career. His 20 triples and 264 total bases were both the fifth-highest total in a season for the Cardinals franchise from between the years of 1892 when they entered the NL to 1920, which marked the end of the Dead-ball era. At the end of the year, he had played 133 games, two behind Major League leader and teammate, Joe Quinn. Offensively, Cooley tied for seventh in most hits and finished fourth in triples.
