Chad Billingsley throws fastballs, changeups in bullpen session

LOS ANGELES -- Dodgers pitcher Chad Billingsley threw 30 pitches in a bullpen session on Tuesday at Dodger Stadium, continuing the slow process of recovery from Tommy John surgery. It was the second time throwing off a mound for Billingsley since getting platelet-rich plasma injected into his right elbow.

Billingsley was limited to throwing fastballs and changeups on Tuesday, and said described the throwing as light.

"There's no real set timetable. Each bullpen session I can add something else to it and keep progressing," Billingsley said. "It might be a week or so before I get a couple more bullpens under my belt, increasing intensity, then adding curveballs."

Billingsley will join the Dodgers on their road trip to Phoenix, New York and Philadelphia, and at some point in the not so distant future will be able to begin another minor league rehab assignment. He pitched into the second inning of one rehab start on April 6 before leaving after feeling something in his elbow.

That turned out to be tendonitis, which essentially shut Billingsley down for almost three weeks. Though he is willing to be patient through the rehab process, Billingsley admitted disappointment in the April setback.

"Mentally it was a little bit of a blow," he said. "I was in a rehab game, just four more outings from being back. It was definitely deflating."

Billingsley last pitched for the Dodgers on April 15, 2013.
