and notching a career slugging mark of .519, highest of anyone who played a majority of his career before 1900.

After two seasons with the Troy Trojans, Brouthers blossomed with the Buffalo Bisons in 1881, leading the league with eight homers and a .541 slugging average. He continued to lead the league in slugging over the next four years. Before the 1886 season, the Detroit Wolverines purchased the entire Bisons roster for $7,000. Brouthers, playing for his third of eleven teams, hit .370, with 40 doubles and 11 homers, and led the league in slugging for the sixth straight season.

Brouthers slugged over .500 11 times during his 19 seasons (he made a brief comeback in 1904 when he played two games with the New York Giants), often topping theleague average by 200 points. He led leagues (the National League, Players League and American Association) in slugging a total of seven times, in on-base average and batting five times, and in total hits four times. What makes Brouthers stand out, however, is his relative dominance. Brouthers led the league in the OPS+ category eight times, his highest being 206 in 1886.
