Throughout his brief career, he showcased his skills on the mound with a record of 3-4 and an earned run average (ERA) of 3.81, a respectable figure for the era that often emphasized pitching finesse over power.

Despite a relatively short career, he remains a part of the rich tapestry of baseball history from a pivotal era in the sport's development.
