Wade LeBlanc was going to start Thursday, but Matt Shoemaker got the nod instead.

SEATTLE -- The Angels currently do have a lefty in their bullpen, and it's Wade LeBlanc -- the guy who was going to start on Thursday until Sean Burnett landed on the disabled list with a torn ulnar collateral ligament, prompting Matt Shoemaker to return to the team and take back his spot.

"I believe I can fill any role they need me to fill," LeBlanc said. "I really do. And I hope they see that. I've improved big-time on effectiveness against left-handed hitters. This year, there's been a noticeable difference than in years past, and it's allowed me to have some confidence against same-side hitters that I haven't had in recent years. I feel like I definitely have that figured out."

LeBlanc -- 5-1 with a 3.69 ERA in nine Triple-A starts -- has done a better job of pitching inside against opposing left-handed hitters, which makes him believe he can be a situational lefty out of the bullpen if needed.

But Angels manager Mike Scioscia said Wednesday "there's no doubt he needs to be stretched out," which probably means LeBlanc will be back in the Minors in a few days and the Angels will have an all right-handed bullpen.

Lefty Nick Maronde cracked the Opening Day roster, but had a 12.79 ERA in 11 Major League appearances, then a 9.35 ERA in nine Triple-A appearances before getting demoted to Double-A. The only two lefties in the Triple-A bullpen are Brandon Sisk (promoted after a 3.60 ERA in 15 innings in Double-A) and Dustin Richardson (10.12 ERA in 13 1/3 innings).

"There are lefties who aren't pitching with us that would be candidates if they can throw the ball with more consistency," Scioscia said. "There are some good arms, but we're going to see how it goes."

There's always the chance lefty Hector Santiago comes back as a reliever, and there's also the chance the Angels just have right-handers -- especially since Michael Kohn and Ernesto Frieri have been better against lefties in their careers.

There's also the trade market.

The Phillies may make Antonio Bastardo available if they fall out of the race. The Padres could dangle Troy Patton. The Reds could do the same with Sean Marshall, though he's had a rough year and is in the second of a three-year, $16.5 million contract. And several other lefty relievers could be acquired via trade, as is usually the case in June or July.

Burnett has torn UCL; Shoemaker recalled

Scioscia on Sean Burnett's setback

SEATTLE -- Fellow Angels reliever Michael Kohn communicated with Sean Burnett for most of the afternoon Wednesday, letting him know he was there for him and providing any encouragement he could muster. At one point Kohn shot Burnett a text regarding Jason Isringhausen, the one-time Angels reliever who underwent Tommy John surgery three times and wound up pitching 16 years in the big leagues.

"He sent me a little text back saying, 'I'll have two and I'm going to pitch for 15,'" Kohn said, shortly after it was revealed that Burnett had torn the ulnar collateral ligament in his left elbow, an injury that typically results in Tommy John surgery and a 12- to 18-month recovery.

"This is not the last time you see Sean Burnett," Kohn added. "He'll be back somehow, someway, some form. He's too good of a pitcher, too good of an athlete, not to be back."

Burnett will have to make that decision on his own, though, and will probably do so when he meets with Dr. James Andrews early next week.

First he'll have to get through the reality of what took place Tuesday night.

Burnett was three appearances into a nine-month rehabilitation from elbow surgery when he threw a 1-2 changeup to Michael Saunders that resulted in a popout to shortstop and will probably be the last pitch he throws in his Angels career. The 31-year-old lefty motioned to the dugout, was removed from the game, and afterwards was too distraught to address a scrum of reporters.

"I was watching him throw and he looked good," Angels pitching coach Mike Butcher said. "He had sink on the ball, he was on top, there was no manipulation. He was free and easy, he had plenty of time to warm up, didn't overthrow any of his pitches down there. He warmed up great, felt great, felt like that was the best he had been throwing since coming all the way back. But you never know in this game."

Burnett flew back to Southern California, where an MRI revealed what he already dreaded. The Angels placed Burnett on the 15-day disabled list Wednesday, calling up right-hander Matt Shoemaker so he can start Thursday.

Burnett had Tommy John surgery in 2004, dealt with elbow discomfort in 2007 and had bone spurs removed from his left elbow after the 2012 season, just before signing a two-year, $8 million contract with the Angels in November.

With the Nationals from 2010-12, Burnett posted a 2.76 ERA and a 1.23 WHIP while compiling 212 appearances.

With the Angels, he was mostly rehabbing.

"When he was with Washington, he was nasty," Angels manager Mike Scioscia said. "We never got to see that part of it with Sean, but you saw the good sink. And he was close."

In 2013, Burnett made two separate trips to the DL, appeared in only 13 games and didn't pitch past late May, after suffering a torn flexor tendon that required surgery that August. Burnett has spent this year working his way back, suffering a temporary setback after a bad reaction to a shot in late March and then gradually working through a rehab assignment before being activated Friday.

Burnett's return lasted all of three batters.

The Angels hold a $4.5 million club option on Burnett for 2015, but are likely to simply buy him out for $500,000 at the end of the season.

"It's just unfortunate," Angels catcher Chris Iannetta said. "You never want to see a guy getting hurt, especially a guy who's working extremely hard, for a very long period of time, to get back on the field.

"He kept having setback after setback, and issue after issue, and it just kept going and going. He had normal human reactions along the way, but didn't let it deter him by any stretch of the imagination. He just kept going, and I'm sure he's going to do the same thing with this one. I'm sure his desire to be out on the field is high, even with all these setbacks. A lot of people, this would've broken them. Not him."

Hamilton tests thumb with batting practice

LAA@SEA: Hamilton injures thumb on dive into first

SEATTLE -- Angels outfielder Josh Hamilton, who suffered a bone bruise on his left thumb during his first rehab game Thursday, felt good while taking batting practice in the cage Wednesday and hopes to hit on the field prior to Thursday's game.

Prior to restarting his rehab assignment with Triple-A Salt Lake, Hamilton wants to hit off a batting machine that spits balls out at a good velocity so he can "mishit a couple of balls and see how it feels."

Hamilton has been hitting without the protective splint on his surgically repaired thumb and said it "feels a lot better."

"The first few swings I took today I was a little timid," Hamilton said. "I was like, 'All right, cut it loose.' So I did, and it felt fine."

Worth noting

• Third baseman Ian Stewart (left hand contusion) played in a couple of rehab games for Triple-A Salt Lake, but is getting evaluated because "his hand is still a little bit sore and they're trying to work out that last little bit of soreness," Scioscia said. He'll be shut down for a couple days.

• Reliever Dane De La Rosa (right s/c joint irritation) has made four appearances since re-joining his rehab assignment with Triple-A Salt Lake, pitching every other day. De La Rosa gave up a run on two hits Tuesday, and has totaled two runs in four innings since returning.
