Pena went 1-for-4 with a solo home run in Sunday's loss to the Mariners.
Pena connected on a 414-foot blast in the seventh inning off Collin Snider. It was his third home run in July and his eighth for the season, though he's struggled to a .190 batting average in 11 games since July 6. After hitting 22 homers in his rookie season, Pena has combined for just 18 since, but he is still putting together a productive season. The 26-year-old is slashing .274/.318/.387 with 43 RBI, 48 runs and an 18:66 BB:K in 404 plate appearances.
