Rojas (forearm) will begin a rehab assignment with Single-A Rancho Cucamonga on Tuesday.
Rojas has been shelved since late July with right forearm tightness but has been cleared for game action. Since his absence has been relatively brief, he shouldn't require many rehab games before being activated. Rojas will overtake Nick Ahmed at shortstop once he's ready. Mookie Betts (hand) is also due back from the injured list soon, though the Dodgers don't seem to have decided on which position he'll play once activated.
