Miami Marlins catcher Jeff Mathis clocked a grand slam in Tuesday's 5-2 win over the San Diego Padres.
The Marlins scored all five runs in the first inning, with Mathis' grand slam coming with two outs.
Mathis, a veteran backup, owns a measly .227 wOBA in 53 plate appearances this season. We project him to post a .223 wOBA with one more homer over the remainder of the campaign.
