In the first game of a scheduled Memorial Day doubleheader in the Three-I League, the Decatur Commodores defeat the Bloomington Bloomers, 2 – 1, in 26 innings. It is the longest professional game played until that time, and won’t be topped until 1960. Both pitchers, Ed Clark for Bloomington, and Otto Burns, making his first professional pitching appearance for Decatur, go all the way. SS Mark Purtell, a .130 hitter for the year, drives in the winning run. The second game of the twinbill is postponed by darkness.
