Guerrier threw his second bullpen session on Wednesday, incorporating offspeed pitches for the first time off a mound. He could soon face hitters, a prelude to a Minor League rehabilitation stint before being activated.
"It's going good right now," said Guerrier. "I'm recovering. I'd like to be back by June 1 if I could. I don't feel any sharp pain anymore, and that's what I was having before."
The Dodgers' bullpen has been one of the trouble points this year, with Javy Guerra losing the closer job to Kenley Jansen, the ineffectiveness of Todd Coffey and inconsistency of Scott Elbert. Meanwhile, Josh Lindblom has moved into Guerrier's workhorse role and Ronald Belisario has returned to take over the innings Coffey was signed to pitch.
