Carlos Beltran happily reported Saturday that he hasn't felt any discomfort in his surgically repaired right knee this season.

He couldn't say the same thing about the left knee, though.

Beltran missed yesterday's game because of tendinitis in his left knee, the good knee. He said he's been dealing with discomfort essentially since he started rehabbing from surgery on his right knee last January.

"Of course you try not to put pressure on the knee you had surgery on, so you start compensating," Beltran said. "It started bothering me during rehab games a little bit."

Beltran said the pain grew worse in the first inning of Friday's game when he stepped on first base while running out a grounder. He remained in the game and hit his first home run since Aug. 16. After the game, he told trainers it was sore and was told to take off Saturday, at minimum.

Beltran said he isn't concerned because he's been managing some level of discomfort all season. He doesn't know whether he will need to miss more than one game.

"It's a little tendinitis, nothing substantial, but something that could keep him from playing every day," manager Jerry Manuel said.

Beltran compared the pain to what he dealt with in both knees during the 2006 and 2007 seasons before choosing to undergo arthroscopic surgery in October 2007. But another knee surgery is not on his mind. "I'm thinking about just finishing the season, go home in the offseason, get back, get ready and get strong," he said.


Extra bases

Two of Ike Davis' four hits came off lefthanders; he's 33-for-105 (.314) against them this season. He said he's comfortable against lefties but refused to discuss why. "I don't want them to know," he said . . . Luis Hernandez started his sixth straight game at second base, with Manuel saying Hernandez gives the Mets the best offensive option at that position. But Manuel said he's going to try to mix in a few starts for Ruben Tejada.
