ANAHEIM -- Mike Bolsinger's visit was brief. Chin-Hui Tsao's will probably be the same.
After activating Bolsinger to start Wednesday night against the Angels, the Dodgers optioned him to Triple-A Oklahoma City this afternoon. Tsao was added to the roster in his place, fortifying a bullpen that has pitched 12 innings in the first three games of the Freeway Series.
Tsao will likely make the return flight to Oklahoma City on Friday. Dodgers manager Dave Roberts indicated the team will go back to a 12-man pitching staff when they return to National League rules Friday in San Diego.
