NEW YORK — Los Angeles Angels catcher Rene Rivera had surgery to repair a torn meniscus in his right knee and likely will be sidelined for 4-to-6 weeks.

Dr. Brian Schultz operated on Friday in Los Angeles following an MRI.

"It's obviously a tough break for Rene right now, a tough break for us," manager Mike Scioscia said.

A 10-year major league veteran, Rivera is hitting .259 with three homers and 10 RBIs in 59 plate appearances over 22 games as backup to Martin Maldonado. Rivera was placed on the 10-day disabled list May 20, a move retroactive to May 17.

The Angels said right-hander Matt Shoemaker had mild fluid in his pitching forearm, according to an MRI on Thursday in Los Angeles. He also was examined in St. Louis this week by Dr. Susan Mackinnon, who ruled out peripheral nerve involvement.

Shoemaker also had a bone scan. He made his only appearance of the season March 31 at Oakland, pitching 5 2/3 innings to beat the Athletics. He was moved to the 60-day disabled list on May 19.

Outfielder Michael Hermosillo was optioned to Triple-A Salt Lake after Friday's 2-1 loss to the Yankees. That opened a roster spot for right-hander, Jaime Barria who is to be recalled and start Saturday.
