LOS ANGELES -- It turns out there was something wrong with Jeff Weaver.
The Dodgers placed the soon-to-be 34-year-old on the 15-day disabled list on Tuesday because of tendinitis in his left knee. Reliever Ramon Troncoso was recalled from Triple-A Albuquerque to assume the vacated roster spot.
Weaver, 5-1 with a 5.35 ERA in 36 appearances, had very visibly struggled in his last five outings, when he let up 10 runs -- half of those in two innings on Monday. Weaver said he first felt pain in his knee a couple of weeks ago, something he had experienced before, but never as persistently.
Weaver did not alert the team until pitching coach Rick Honeycutt talked to him after Monday night's 10-5 loss to the Padres.
"For a couple outings, it was irrelevant and I had some success, so I didn't really think twice about it," Weaver said. "But now when it's affecting the outcome of games, it's in all of our benefits not to go out there. They talked to me after the game yesterday. Command is a big part of my game ... obviously they're going to ask questions about what's going on. I guess it's time to throw pride aside and take care of it and come back 100 percent."
Manager Joe Torre wasn't disappointed Weaver hadn't said anything earlier.
"I don't necessarily need for guys to tell me about all your aches and pains," he said. "I think when it comes time that it starts affecting your performance, that's when you want to know."
Weaver said he had yet to work out a plan with team trainer Stan Conte, who was in Arizona tending to Manny Ramirez on Tuesday, but expected to avoid cardio and other activities that affected his knee.
Weaver felt 15 days would be enough time to recover and said there was no one moment when he first started to feel the pain. He also acknowledged the possibility that his age had something to do with the injury.
The 27-year-old Troncoso was optioned on July 3 after he went 1-2 with a 5.15 ERA in 39 appearances. The right-hander had a 2.72 ERA last season and a 3.46 ERA this April but struggled after that. He said he worked on his sinker and keeping his left shoulder square to the plate with the Isotopes.
Troncoso struck out three in two perfect innings in his last Triple-A outing Saturday. He had a 6.91 ERA in 14 1/3 innings.
"He's OK," Torre said. "Inconsistent. You know, we'll see. He gives us a guy that can throw a couple innings."
