Madson, who filled in as Philadelphia's closer in Lidge's absence, went on the disabled list Friday with a broken right toe — sustained when he kicked a chair after blowing a save in Wednesday's 7-6, 11-inning win over San Francisco, his second blown save in six opportunities.
"I'm embarrassed. I let down my teammates," Madson said. "I let down the fans that want us all to be out there playing hard for them. I feel terrible about that. That's the worst part. I've done it before. Not kick stuff, but I've gotten upset before and never broken a bone. It's just one of those things. I learned from it. I won't do it again. I realize how much I'm letting my teammates down and the fans."
Madson is 1-0 with four saves in six chances and a 7.00 ERA in nine games this season. To replace him on the roster, the Phillies recalled left-hander Antonio Bastardo from Triple-A Lehigh Valley.
Lidge also was activated for Friday night's game against the New York Mets. He went 0-1 with a 5.19 ERA in eight rehab appearances while recovering from two offseason surgeries.
Madson said he slipped down a flight of stairs leading from the dugout to the clubhouse. He maintained his balance, but the stumble only fueled his frustration, and he punted a heavy metal folding chair.
He initially thought he had stubbed his toe, but had trouble walking on Thursday. The team took X-rays later that day and Madson was in a protective boot on Friday.
"I tried to kick it over," he said. "I caught my toe underneath the chair instead of on top, and that's pretty much what happened. (The chair) just happened to be right there. It was bad timing."
With Madson out, it seems likely that Jose Contreras and J.C. Romero will see most of the setup duties. The Phillies are unsure how long Madson will be sidelined.
"I don't think we're 100 percent certain," assistant general manager Scott Proefrock said. "It's got a chance to be more than 15 days. It depends on how he heals. Obviously, we're not going to put him out there before he's 100 percent because we don't want him to do anything to hurt his arm."
