TEMPE, Ariz. -- Angels reliever Bobby Cassevah is hoping to avoid starting a second straight season on the disabled list, but the spring is quickly running away from him.

Cassevah has yet to appear in a Cactus League game because of inflammation in his right shoulder, which flared up once again during a bullpen session earlier this week and forced him to temporarily shut it down.

The 26-year-old sinkerballer hopes to be cleared to pitch off a mound again on Monday, and then get in game action later in the week. He's thinking that timetable could be enough to have him ready for the season.

"I think so," Cassevah said. "As long as I get in a [simulated] game Wednesday or Thursday, and then face some live hitters a couple of times, that's about it. That's all you need."

Cassevah missed 17 games with shoulder inflammation last April, but was a crucial member of the Angels' bullpen upon being called up from Triple-A in mid-June -- posting a 2.72 ERA and a 1.19 WHIP in 30 games down the stretch.

"Hopefully I can be ready [to start the season]," Cassevah said. "I see the doctor tomorrow and hope to start throwing again tomorrow."

Moore to undergo hip surgery on Monday

TEMPE, Ariz. -- Jeremy Moore expects to undergo left hip surgery to take care of a bone spur on Monday. The procedure, which will take place in Nashville, Tenn., will sideline the Angels' young outfielder an estimated three to five months.

"It's definitely not what I wanted," Moore said, "but it's best to get it out of the way as soon as possible."

Moore, who has been dealing with hip problems the last two years and has yet to appear in a Cactus League game, plans on gaining 10 pounds of muscle during the time he's out to come back, as he put it, "bigger, faster, stronger."

A speedy left-handed hitter who can handle all three outfield spots, Moore saw action in eight games with the Angels as a rookie last year and has produced a .277/.329/.473 slash line in seven seasons in the Minors. Moore was cleared to begin his running program early in camp, but had a setback and was never able to get back on the field.

The 24-year-old would've started the season at Triple-A Salt Lake.

Adding a starter not a priority for Dipoto

TEMPE, Ariz. -- Despite recently being linked to free agent Roy Oswalt, Angels general manager Jerry Dipoto said he's "not particularly" looking to add another starting pitcher.

On Friday night, former GM Jim Bowden, currently with ESPN, said on Twitter that the Angels were "suddenly the front-runner" to land Oswalt, with the Red Sox still in the hunt and the Rangers and Cardinals fading out.

"I can't qualify for everything you hear," Dipoto said. "But I can say that we're quite happy with the way our starting pitchers have thrown this spring and the way they've developed. You never have enough pitching, so it's tough for me to say that there's not a time in this season where our situation may not change, but right now, we're very happy with where our pitching is."

Jerome Williams, who came into camp as the favorite for the fifth spot, has been out for more than three weeks with a strained left hamstring, but expects to make his first start Monday, which would figure to give him enough time to be ready by April 15 -- the first time the Angels would need a fifth starter.

No. 3 prospect Garrett Richards is also competing for the fifth spot, with Trevor Bell and Brad Mills in camp as other potential options.

Oswalt, 34, had previously said he'd prefer to pitch close to his Mississippi home, but backed off that due to waning interest, telling teams he'd be willing to pitch anywhere and even indicating he's open to a midseason return.

Oswalt's agent, Bob Garber, could not be reached for comment on Saturday.

Dipoto said he's constantly seeking depth behind Jered Weaver, Dan Haren, C.J. Wilson and Ervin Santana, but mostly via Minor League deals or waiver-wire pickups. Like 28-year-old right-hander David Pauley, who was signed Friday but will not report to big league camp.

Pauley, who posted a 3.16 ERA in 53 relief appearances for the Mariners and Tigers last year, will instead get stretched out in the Minor Leagues in hopes of contributing at some point during the season.

"This is an effort to build organizational depth so that when you get to those points in the season, which are inevitable, that you're going to call on pitching depth, and you have guys in Triple-A that provide it," Dipoto said. "David has a chance to be part of that equation."
