San Francisco Giants manager Bruce Bochy told reporters Friday that Matt Cain will be placed on the 15-day disabled list due to a first-degree hamstring strain. Yusmeiro Petit take Cain's turn tomorrow against the Cardinals.
The Giants have recalled outfielder Juan Perez from Fresno. He will join the team tomorrow in St. Louis.
This is the second trip to the DL this season for Cain, who landed on the DL for the first time in his career last August after taking a liner off his right forearm. He missed time earlier this season due to a freak accident of sorts, when he cut his right index finger with a kitchen knife while making a pregame sandwich.
Cain injured his hamstring in Colorado on May 21, grabbing the back of his right leg after throwing the final pitch of the third inning. Three days later he threw a bullpen session that was cut short after about 15-20 pitches. He'll be eligible to return on June 6.
Instead of moving Cain (1-3, 3.66 ERA) to the DL right away, the Giants held out hope that he would only miss one start. Cain threw on flat ground and ran sprints on Thursday, but in the end the Giants decided to exercise caution.
Petit (3-2, 5.08) will make his fifth start of the season tomorrow, his fourth in place of Cain. Petit has struggled as a starter since tossing six scoreless innings in his first start of the season, with an ERA of 7.08 in that role compared to 2.89 in 10 relief appearances. He allowed four earned runs over five innings in Monday's 8-4 loss to the Cubs.
