Athletics starter Jarrod Parker had to leave this afternoon’s game against the Cardinals in the fourth inning after surrendering a two-out double to Allen Craig. As Parker followed through on the pitch, he crumpled to the ground, clutching at his right leg. CSN Bay Area’s Nate Stuhlbarg is reporting that the right-hander suffered a hamstring injury.
Parker, entering today’s game with a 4.27 ERA over 16 starts, had held the Cardinals scoreless, but reliever Jesse Chavez allowed two runs in the fifth and put runners on first and third with no outs before being replaced by Jerry Blevins in the sixth. Both runners would come around to score as Blevins opened the floodgates for the Cardinals as they hung up a four-spot.
