Philadelphia Phillies ace Roy Halladay is expected to miss six to eight weeks because of a strained right shoulder, the latest major setback for the five-time NL East champions.
Halladay was put on the 15-day disabled list Tuesday, two days after he was hit hard and pulled from a start in St. Louis after two innings because of shoulder soreness.
The two-time Cy Young winner will be shut down for a minimum of three weeks, then work toward rejoining the rotation, Phillies assistant general manager Scott Proefrock said.
Proefrock said tests done in Philadelphia indicated Halladay doesn't need surgery to recover and that the injury doesn't affect his rotator cuff.
"We hate to have him down, but it's nothing that requires anything other than rest," Proefrock said.
Halladay is 4-5 with a 3.98 ERA in 11 starts this season.
ANGELS: Ace Jered Weaver has been placed on the 15-day disabled list with a lower-back injury that likely will force last season's AL Cy Young runner-up to miss at least two starts.
The Angels made the move Tuesday, recalling touted prospect Garrett Richards from Triple-A Salt Lake.
Weaver threw just 12 pitches Monday night against the Yankees before pulling up awkwardly after a pitch to Robinson Cano. He was diagnosed with lower back spasms and a strained muscle around a disc in his lower spine.
Weaver is 6-1 with a 2.61 ERA and threw a no-hitter against Minnesota on May 2.
RANGERS: Texas agreed to a minor league deal with free-agent pitcher Roy Oswalt, expecting the three-time All-Star to join their rotation within a few weeks. Assuming Oswalt passes a physical Thursday, he is expected to go to Triple-A Round Rock and make his first start Saturday.
INDIANS: Closer Chris Perez has angered Kansas City's Jarrod Dyson for a gesture he made after striking out the outfielder. Perez mocked Dyson by waving his hand in front of his face — a move popularized by pro wrestler John Cena — in the ninth inning Monday. Dyson called the gesture "terrible."
NATIONALS: Infielder Chad Tracy will require surgery for a torn groin muscle and is expected to be sidelined at least six weeks.
TIGERS: Prosecutors are not offering a plea deal to outfielder Delmon Young, who is accused of making anti-Semitic remarks during a fight outside a New York hotel.
