Los Angeles Dodgers right-hander Walker Buehler will undergo an MRI on Saturday after leaving his start early because of discomfort in his right elbow in a 7-2 loss Friday night to the San Francisco Giants.

Buehler said he felt something in the elbow in the last couple of innings of the start, adding that he tried to pitch through his discomfort but couldn't.

"I threw a breaking ball in the third inning and it kind of grabbed a little bit and kind of didn't go away," Buehler said. "I tried to pitch through it to see if it would pop away. Sometimes that'll happen, but it didn't happen for me tonight."

Buehler allowed three runs and four hits in four innings, losing for just the second time in his career in nine decisions against the Giants. He fell to 6-3 this season with a 4.02 ERA.

Buehler emphasized the need for the results of tests on the elbow but hinted that his current bout with elbow woes is his most serious one of late.

"I've had stuff for years and years in the elbow," he said. "Pretty consistent, same spot for the last couple of innings. It is what it is. We'll get it looked at, see what we're dealing with before we freak out, I guess."
