In watching Ken Burns' "Shadow Ball" special on the Negro Leagues of the 1930's, I got interested in looking up game stats of one Satchel Paige. What's struck me is that he didn't pitch many innings (Usually 4-6 a game) and sometimes was used as a reliever. This blows my mind as I always thought of Satchel as somewhat of a Hal Newhouser type (Averaged almost 7-8 innings per game pitched from 1944-1946).
Now Paige definitely had a live arm with great strikeout ability but I'm still surprised to see many of his games being just 3-5 IP (this includes against MLB All-Stars in exhibitions). It seems he'd often start for the first 3-5 IP then leave the game for a reliever.
