Marlins reliever Dan Jennings was struck on the left side of his head by a comeback line drive in the seventh inning, and he was carted off the field at PNC Park.
The scary moment occurred with one out in the seventh inning. Pittsburgh's Jordy Mercer ripped a line drive up the middle that deflected off Jennings' head, and the ball deflected straight up in the air.
Jennings struggled to maintain his balance as catcher Jarrod Saltalamacchia raced to the mound to tend to the left-hander. Marlins trainer Sean Cunningham and manager Mike Redmond also rushed out there as Jennings dropped to a knee, clearly dazed. The stadium turned silent as fans and players from both dugouts displayed concern.
