Yankees closer Mariano Rivera said the blood clot in his right calf has cleared up and he will have surgery on his injured knee June 12. Baseball's career saves leader was at Yankee Stadium on Wednesday before New York's game against the Tampa Bay Rays, walking without a limp despite having a torn ACL and damaged meniscus.

He said he should be ready to play at the beginning of next season. "Oh yeah, there's no doubt about that, God willing," Rivera said.

The 42-year-old was hurt shagging flyballs on May 3. Surgery was delayed because doctors discovered the clot. Rivera learned last week that the clot was gone and said his knee has been strong enough for surgery for a while.

Mets team physician David Altchek will perform the operation. Rivera said there's no timetable for his return and that he doesn't want one.

Coming back

Baltimore signed 49-year-old left-hander Jamie Moyer to a minor-league deal and assigned him to Triple-A Norfolk. The Rockies released Moyer at the end of last month, a little more than a month after he became the oldest pitcher to win as a starter. He is expected to start for Norfolk on Saturday at Buffalo. . . . Boston right-hander Daisuke Matsuzaka is expected to start Saturday against the Nationals, one day short of a year after he had elbow reconstructive surgery. . . . The Phillies have activated Jim Thome from the disabled list. Thome had been sidelined with a lower back strain since April 29. He could get plenty of at-bats as a designated hitter with nine interleague games coming up.

Pulled muscle sidelines Stubbs

The Reds called up utility player Kristopher Negron from Triple-A Louisville on Wednesday, giving them another outfielder while Drew Stubbs recovers from a pulled muscle in his side. Stubbs was hurt on a swing during an 8-4 loss to Pittsburgh on Tuesday.

Clemens trial

Eileen McNamee presented herself as a soft-spoken first-grade schoolteacher who never nagged her now-estranged husband about Roger Clemens, whose trial continued in Washington. She went on to contradict the government's key witness many times. On a day in which the judge lost his temper twice with Clemens' lawyers, the defense turned to the soon-to-be-ex-wife of Brian McNamee, who had testified she harangued him until he saved medical waste from an alleged steroids injection of Clemens so that he wouldn't be the fall guy in any sort of drugs investigation. She testified she did nothing of the sort.

West Coast update

Oakland outfielder Collin Cowgill, who played at Henry Clay and the University of Kentucky, hit a two-run homer off Texas pitcher Derek Holland Tuesday night. The homer, Cowgill's first of the season and his second in the majors, went 399 feet in left-center. But the Rangers won the game 6-3.
