The Pirates brought in Grilli to close during the ninth inning of a 6-3 game. The closer surrendered two runs in the inning, but managed to record two outs before facing Steve Lombardozzi with the tying run on second base.
Grilli threw a fastball to Lombardozzi, but immediately called for the trainers after the pitch and looked to be in significant pain, according to Amanda Comak of the Washington Times. Vin Mazzaro replaced Grilli, and forced Lombardozzi to hit a game-ending groundout.
For the superstitious, Grilli appeared on the cover of Sports Illustrated last week, the first Pirates player to appear on the cover in 21 years, according to the MLB PR Department:
Grilli has thrived in the closer role this season, as he entered Monday with 30 saves in 31 chances and a 1.94 ERA. Mark Melancon will likely serve as the team's closer if Grilli is forced to miss an extended period of time.
