LOS ANGELES -- Angels left-handed reliever Sean Burnett, who missed most of last season with an elbow injury, threw his second successful bullpen session Thursday at Dodger Stadium in the afternoon.
"This is the best he's been since he's gone back out there," pitching coach Mike Butcher said. "The guy we're looking for is the guy who was out there today.
"He threw all his pitches. He had a heavy sink. We'll see how he comes out of this, and go from there, see if he can pitch back-to-back days."
Burnett's first season with the Angels in 2013 was limited to 13 appearances covering 9 2/3 innings with a 0.93 ERA.
"He hasn't pitched for a year, so he needs to go have a Spring Training," Butcher said, "but if he keeps progressing like this, it won't be long before he's facing some hitters."
Meanwhile, right-hander Dane De La Rosa (forearm) pitched a Minor League inning in Arizona.
"He felt good, he looked good," manager Mike Scioscia said. "It's an important first step. We'll see how he responds."
