I see the confusion, as it appears Greg was mistaken, either that or retrosheet is in error. In post 243 Greg says he got the photo from the July 6, 1911 paper, but that must be a typo--he surely meant May 6. If you blow up the story that appears with the photo, you see how ChiSox pitcher Frank Lange baffled the Indians in that game, beating them 2-1. That matches with the retrosheet site for the game played May 5th-- the Indians 20th game of the season.
