McCann entered Saturday's win over the Orioles as a pinch hitter in the eighth inning and hit a two-run home run in his one plate appearance.
McCann's blast ironically came off namesake and fellow backstop James McCann, who was in as a reliever at that point with the Orioles down 17-6. McCann's homer plated Max Schuemann with the final runs of the night for the Athletics and served as his first time leaving the yard since May 7, a span of 21 games for the occasional fill-in catcher. The rookie has been impressive at the plate overall during his first taste of big-league action this season, with Saturday's production pushing his slash line to a stellar .291/.390/.465 across 100 plate appearances.
