The slender, strong-armed Bagby won 23 games in 1917 and 17 in each of the next two seasons. In 1920, when Cleveland won its first pennant, he led the AL in wins (31), winning percentage (.721), innings (339.2), hits allowed (338), and relief wins (6). In the World Series against Brooklyn he lost Game Two but came back to win Game Five. Bagby went the distance, giving up 13 hits but only one run, and became the first pitcher to hit a World Series home run. Two other Series firsts by teammates helped him: Elmer Smith’s grand slam homer and Bill Wambsganss‘ unassisted triple play. His son, Jim Bagby Jr., also became a major league pitcher.
