Galvin was in the P WAR leader -- I guess he wasn't as valuable a hitter as Keefe (in their respective best seasons)
Joe you are right on Big Sam Thompson -- he was well over an RBI per game played in few seasons in the 1880's and 1890's...In the 1890's he had Billy Hamilton batting in front of him.
The SB leader was Hugh "little Nic" Nichol in 1887 in the AA -- I think the stats were especially crazy that year and I don't think they defined SBs the way we do now. But Nichol is still the recognized all-tiime Single-Season leader just ahead of Rickey Henderson.

The Wild Pitch record holder is Mark Baldwin -- who was not Charles "Lady" Baldwin. Mark threw 83 WP in 1889... 20 more than second place all-time Tony "Count" Mullane who is still the career total leader... 83 WP is a lot. Cy Young only ran up 156 in his endless career. Greg Maddux had 70.
