Another day, another Giant heads to the disabled list.
The Giants placed left-handed reliever Jeremy Affeldt on the 15-day disabled list Sunday after he experienced a left groin strain on the mound against the Arizona Diamondbacks on Saturday. The team recalled right-hander Jean Machi from Triple-A Fresno to replace Affeldt on the 25-man roster.
The Giants' medical staff expects Affeldt to be out for a minimum of six weeks.
Affeldt said he'd felt uncomfortable for a while, but he knew the injury was serious after he felt a "pop" during the sixth inning of Saturday's game.
"Something obviously went wrong," he said.
The set-up man had struggled in recent weeks, posting a 5.93 ERA in his last 13 2/3 innings of work.
He said it's possible that he altered his delivery to compensate for the groin pain.
"When you feel pain sometimes you let the ball go [early]," he said. "You're just dealing with uncomfortable-ness, so you're not mentally making the right pitches."
Manager Bruce Bochy said he was unaware of Affeldt's discomfort.
"As far as the knowledge I have, he was feeling fine, good to go," Bochy said. "So if that's the case, he kept it to himself."
Without Affeldt, Bochy will only have two left-handers, Jose Mijares and Javier Lopez, at his disposal in the bullpen.
"It's disappointing," Bochy said. "Jeremy is valuable in the fact you can use him anywhere, he can pitch multiple innings, he's one of our lefties."
But Bochy said he's comfortable using Machi in a variety of situations. Entering Sunday's game, Machi is 2-0 with a 3.58 ERA in 26 appearances this year.
"I can put him in there against righties or lefties," Bochy said.
