ANAHEIM -- Mike Bolsinger was optioned to Triple-A Oklahoma City on Thursday, a day after his spot start against the Angels. Right-hander Chin-hui Tsao was called up to replace him on the 25-man roster.
Bolsinger labored through 4 1/3 innings against the Angels, allowing three runs and seven hits while being forced to work almost entirely off his slider. The right-hander was on an 80-pitch limit since he was making his debut after a DL stint with an oblique strain.
Tsao will slot into the Dodgers' bullpen after registering a 3.31 ERA in 16 1/3 innings and six saves in seven opportunities with Oklahoma City.
