ANAHEIM, Calif. -- The Los Angeles Angels hope that left-hander Joe Thatcher can fill a two-year-old void in their bullpen.
The Angels acquired Thatcher and outfielder Tony Campana from the Arizona Diamondbacks on Saturday for two minor-leaguers. With the Diamondbacks, Thatcher went 1-0 with a 2.63 ERA in 37 games, amassing 25 strikeouts and conceding just three walks in 24 innings.
"He's not a guy who has to be a situational, one-on-one left-hander," Los Angeles general manager Jerry Dipoto said. "He's funky. He's tough to pick up. He makes left-handers very uncomfortable, and he's also capable against a righty."
Angels manager Mike Scioscia said of Thatcher, "(He is) one big piece that will definitely take the load off some guys that have been pitching a lot."
Thatcher is the Angels' latest attempt to find capable left-handed relief. Dipoto signed Sean Burnett as a free agent in 2012, but elbow problems limited Burnett to just 16 appearances in two seasons. After undergoing Tommy John surgery last month, Burnett is out for the season.
Brian Moran also is out for the season after having Tommy John surgery in April. Michael Kohn was shipped to the minor leagues and recalled twice after being designated for assignment and clearing waivers. Veteran Wade LeBlanc made one relief appearance before the New York Yankees claimed him off waivers.
Before acquiring Thatcher, the Angels auditioned Rich Hill, whom they purchased July 1 off waivers for $1. Hill, who made 25 appearances earlier this season for Boston's Triple-A Pawtucket affiliate, pitched in both games of a doubleheader against the Chicago White Sox when he arrived last week.
Hill faced a combined four batters in both games, did not record an out and was released Saturday.
In his debut Sunday, Thatcher threw just one pitch, which Houston Astros designated hitter Jason Castro lined up the middle for a single. However, on Monday night against the Toronto Blue Jays, Thatcher induced designated hitter Adam Lind to fly out and catcher Dioner Navarro to ground out.
"When you're looking to clean up that inning with runners on base and get the key out with a left-handed hitter, it's something we've been missing all year long," Dipoto said. "We just haven't had it. Joe Thatcher is our shot at an answer."
Thatcher did not pitch Tuesday in the Angels' 4-0 loss to the Blue Jays.
