Right-hander Ken Giles will take Adams' spot in the Phillies' bullpen. Giles, who touches 100 mph with his fastball, has been on the minds of fans since he started to put up eye-popping numbers in April with Double-A Reading. He had a 1.20 ERA in 13 appearances with Reading. He struck out 29 and walked five in 15 innings.
He was promoted to Triple-A Lehigh Valley early last month. He posted a 2.63 ERA in 11 appearances, but struck out just nine and walked eight in 13 2/3 innings.
"He's had some good outings," Phillies manager Ryne Sandberg said. "He's the next guy in line for us. We saw him in the spring and his control has been better and he's made some improvement."
But Adams' results will be difficult to replace. He went 2-1 with a 2.12 ERA in 19 appearances. In 17 innings, he allowed 13 hits, four earned runs, seven walks and struck out 20. He started the season on the disabled list following right shoulder surgery in July.
"That's a blow, yeah," Sandberg said. "He's been like a second closer to us. Shut-down guy in the seventh or eighth inning."
"It had been bugging me a little bit since the last outing against New York back home," Adams said of his May 30 appearance against the Mets. "I asked for two days off to see if it would go away with a little rest. We'll take a look at it Monday and maybe do an injection to see if it clears up. Hopefully it does."
Adams, who has had two shoulder surgeries in his career, had not pitched in six days until he threw just five pitches in one-third of an inning Friday against the Reds.
He woke up Saturday with discomfort in the shoulder.
"I'm always worried about it, especially considering the history," Adams said. "Any time I felt a little bit of discomfort, I got worried. I don't want to try to throw through this right now. It's still pretty early in the season. Hopefully, if we can clear it up and strengthen it back up, it'll go away."
Adams started the 2009 season on the DL following his first surgery. He rejoined the team in June, but missed some time in August and September with a strained right shoulder. He came back from that OK.
He hopes this is similar.
"My shoulder felt like it was going out on me," Adams said. "So I went on the DL and strengthened it back up and everything was fine after that. Hopefully, it's the same situation. I'll keep my fingers crossed and hope that's the way it plays out."
