Perez (ankle) will begin a rehab assignment at High-A Rancho Cucamonga on Monday, Eric Stephen of True Blue LA reports. Perez will throw one inning with Rancho Cucamonga, and that may end up being the extent of his rehab assignment. He's eligible to return from the DL on Tuesday, though the Dodgers could choose to wait an extra day to afford him some additional recovery time following Monday's outing.
