ANAHEIM -- Although the Angels did not make a bullpen-related roster move Friday, the carousel in the 'pen continued.
Garrett Richards -- who began the season in the bullpen and was moved to the rotation when Jered Weaver went on the disabled list with a left elbow fracture -- is back in the bullpen and Jerome Williams will take his place in the rotation Sunday against the Orioles.
"We definitely need to look at shuffling some things around to get a deeper look in our bullpen. There's no doubt about that, first and foremost," Angels manager Mike Scioscia said. "Garrett Richards' arm in the bullpen is definitely a power arm that we hope can take some of the pressure off the guys that are pitching a lot there."
The 24-year-old right-hander was 1-2 with a 5.54 ERA in four starts for the Angels.
Williams has a 1.69 ERA in 21 1/3 innings this season and has not allowed an earned run in his last 13 innings pitched -- six of which came in Monday's 19-inning game at Oakland.
"The way Jerome has been throwing the ball in his multi-inning looks has been what we expected and what we saw in some of his starts last year," Scioscia said.
Ultimately, Richards wants to be a starter in the Major Leagues but is fine being used in the bullpen.
"I like the rush out of the 'pen, but I like the preparation of being in the rotation," Richards said. "There are things about both that I like."
Richards was informed he would have a "prominent role" in the back end of the bullpen.
"Right now we are planning to have him hold leads or pitch in tied games," Scioscia said. "Instead of once every five days in the rotation, maybe three of those days he's helping you hold leads in the 'pen."
The Angels have used 19 pitchers this season and their bullpen currently consists of just three pitchers -- including Scott Downs, who is dealing with pain in his right rib cage -- that were in the bullpen on Opening Day.
While Richards is open to helping the team and pitching in whatever role is necessary, the Angels are seeking a set role for him to avoid the back and forth that has occurred this season.
"It is not preferable," Scioscia said. "In a perfect world this is a one-way trip for Garrett and he becomes a power arm for our bullpen that we can use to help hold leads."
Callaspo returns to lineup against Orioles
ANAHEIM -- Slowly but surely the Angels appear to be getting healthier.
Earlier this week shortstop Erick Aybar was activated from the disabled list, and prior to Friday's game against the Orioles, third baseman Alberto Callaspo was activated as well.
"Finally we are back and we're going to give 100 percent to the team," Callaspo said.
To make room for Callaspo -- who has been on the disabled list with a right calf strain since April 19 -- infielder Andrew Romine was optioned to Triple-A Salt Lake.
Callaspo, who was hitting .273 in nine games this season, played the past three days on a rehab assignment with Class A Inland Empire where he went 2-for-7 with a home run.
"I was trying to work out and look for some pitches," Callaspo said of his rehab stint. "I came back quick. I just want to play here. It was sore [the first day back] but now it feels good."
Callaspo hit seventh and was in Friday's lineup at third base for the Angels.
Burnett to meet with specialist about forearm irritation
ANAHEIM -- Left-hander Sean Burnett, restricted to throwing off flat ground since landing on the disabled list with left forearm irritation, is scheduled to visit renowned orthopedist Dr. James Andrews in Florida on Monday.
Burnett, out of action since last Saturday, does not expect anything to come of the visit but has had arm troubles in the past and wants to make sure everything checks out.
"It feels fine, but I haven't thrown off a mound," said Burnett, who is eligible to come off the DL on May 12.
The Angels reliever had Tommy John surgery in September 2004 and also had surgery this past offseason to remove two bone spurs from his throwing elbow.
After visiting with Andrews on Monday morning, Burnett plans to fly to Houston that afternoon to rejoin his teammates.
Jimenez an 'emergency' option in Angels' outfield
ANAHEIM -- Since making his Major League debut on April 12, infielder Luis Jimenez has made a strong impression with his glove at third base in 18 games while Alberto Callaspo was on the disabled list.
"I don't know if you could ask any player to come up and do anything else on the defensive side," Angels manager Mike Scioscia said. "He's done everything you could ask any player to do on the defensive side and it's helped us win games."
Prior to Friday's game, the Angels activated Callaspo from the disabled list, but kept Jimenez on the 25-man roster because of his defense and his versatility.
As Callaspo retakes his role as the team's everyday third baseman, Jimenez may find his new role in left field as he spent Friday afternoon using Mark Trumbo's glove to get in some outfield work.
"I just am ready and available for anything they need me to do," Jimenez said. "Any spot that they need anything. If I'm here, I'll be able to do it."
Scioscia said Jimenez will be used in left field on an "emergency basis," but the 25-year old is confident and comfortable with his abilities in the outfield as he spent some time out there during the Caribbean series.
"I'm OK. Anywhere they need me, I'll be OK," Jimenez said. "If I can make the routine play, I'll be OK."
• For the second straight year, the Angels will not have a first-round pick in Major League Baseball's First-Year Player Draft. The Angels forfeited their first-round selection with the signing of Josh Hamilton. The Angels' first pick comes in the second round and is the 59th overall selection. They also have the 95th overall pick, which comes in the third round.
The Angels did not have a pick in the first two rounds last year and used their 2011 first-round pick on first baseman C.J. Cron.
• Reliever Mark Lowe is eligible to come off of the disabled list Sunday but expects to make one more Minor League appearance. Lowe pitched two innings for Class A Inland Empire on Thursday night and plans to throw another two innings on Sunday.
• Tommy Field has a broken right index finger and is on the Minor League disabled list. Field will likely miss a month with the injury.
