DENVER -- Chad Billingsley resumed his rehab assignment on Sunday with Class A Advanced Rancho Cucamonga, pitching 1 2/3 shaky innings before reaching his 30-pitch limit.
Billingsley, who underwent Tommy John surgery last year, had to restart a rehab that was shut down two months ago when he developed flexor tendinitis in his right arm.
Billingsley allowed one run on two hits and two walks, hit a batter and struck out two.
