ST. LOUIS -- Giants right-hander Matt Cain will be put on the disabled list for the second time in two months. Cain strained his right hamstring May 21 and hasn't started since. He was scheduled to return to the mound Saturday against the St. Louis Cardinals, but the Giants opted to take a cautious approach.
"We're going to take the safe route here," Bochy said. "It's a few more days to where we'd really be convinced he was 100 percent. We just at this point don't think it's worth the risk. We don't want to put him in a situation where he's at risk of re-injuring this."
Bochy said Cain felt fine while running and throwing, but there's still a little something nagging him in that strained hamstring. Cain wanted to start, but was overruled. Yusmeiro Petit will replace Cain for a second straight time. Outfielder Juan Perez was recalled from Triple-A Fresno to take Cain's roster spot.
Cain is tentatively scheduled to come off the disabled list June 6 and start the opener of a homestand at AT&T Park. Bochy said that if Saturday's game was taking place in September and not May, Cain would be cleared to take the mound. But with a 61/2-game lead in the division, there's no point in pushing one of their most important players. Cain had never been on the disabled list before getting hit by a line drive last summer. He was placed on the DL this April after cutting his finger while styling a ham and cheese sandwich.
Cain isn't the only Giants star nursing an injury. Catcher Buster Posey was out of the lineup a second straight day because of nerve irritation in his lower back.
