Don Mattingly is pessimistic about the prospect of left-hander Hyun-Jin Ryu making his next start, per the Los Angeles Times. Ryu managed to pitch 5 2/3 innings in a loss to Atlanta on Wednesday night before being pulled with a glute injury that will require an MRI.

The loss for any length of time would be a blow to the Dodgers. Ryu racked up five consecutive quality starts before his latest outing, during which he yielded just seven earned runs in 33 innings pitched.
