Rockin' the sure shot.
Why we like him: Fred "Sure Shot" Dunlap was a machine in 1884 for the St. Louis Maroons. He also had what was arguably the fourth-best offensive season any player has ever had (if you go by the ever silly and contrived OPS+ stat). He led the league with balmy .412 batting average, and he also led the league in homers (just 13, but still), hits, and runs. All of that was good enough for a "Bondsian" OPS+ of 256, which is, like I said, the fourth-best mark ever just behind three Bonds seasons and even just ahead of three seasons by some guy named Ruth.
The crazy thing about Dunlap's career is that he never did anything else remotely remarkable (Okay, he did lead the league in doubles with 27 in 1880 as a rookie). He finished up his 12-year career at the age of just 32 as a lifetime .292 hitter. He even played in (and won) the 1887 World Series for the long defunct Detroit Wolverines against the St. Louis Browns, batting just .150 for the series.
Ladies and gentlemen, Fred Dunlap, ballplayer.
