Guerrier said he still feels some discomfort just playing catch, but will increase the intensity of his throwing to see if he can pitch through it. A platelet-rich plasma injection during the last homestand had little effect and he doesn't intend on having another.
"The doctor said I'm ready to go forward," Guerrier said. "I've been playing catch just to maintain the motion in my arm, but now it's time to pick it up."
If Guerrier is not able to pitch through the discomfort, he might shut down throwing for an extended time.
Manager Don Mattingly said Rubby De La Rosa and Blake Hawksworth remain in extended spring training healing from elbow operations.
