Rosario went 1-for-5 with a grand slam in Sunday's win over the Diamondbacks.
The 31-year-old played hero by belting a Miguel Castro pitch to right field in the ninth inning, erasing a 5-4 deficit. Rosario has three homers in the last three games to give him eight long balls on the year, and after a rough start to the season at the plate he's slashing .286/.290/.538 over his last 25 contests.
