Joining the Detroit Tigers in 1903, Bill Donovan was a solid Pitcher who in 1907 helped the Tigers to the Pennant when he posted (what is still) a franchise best winning percentage with a 25 and 4 record.  He was a big part of them winning the next two Pennants and would overall have a record of 140 and 96.  Donovan was also an above average hitter for a Pitcher and batted .207 for Detroit.
