Earlier in the season, he had been the losing pitcher in the previous no-hitter to this one, by the Philadelphia Phillies' Johnny Lush on May 1.

In a six-season career, Eason posted a 36–73 record with 274 strikeouts and a 3.42 ERA in 951+1⁄3 innings pitched.

After his retirement as a player, he worked as a National League umpire from 1910 to 1917.

Eason died in a house fire in Douglas, Arizona, at the age of 91.
