The Dodgers reinstated Rojas (forearm) from the 10-day injured list Wednesday.
Rojas landed on the injured list July 24 due to right forearm tightness, and he played in just one rehab game in Single-A. However, now back on the active roster, the 35-year-old will likely start at shortstop until Mookie Betts (hand) is able to return from the IL. James Outman was optioned to Triple-A Oklahoma City in a corresponding move.
