Yankees star Aaron Judge is experiencing discomfort in his right elbow and is not in the starting lineup for Saturday’s game against the Phillies at the Stadium.

Manager Aaron Boone said before the game that the club doesn’t know the extent of the injury, that the two-time AL Most Valuable Player was sent for imaging tests and that they are awaiting the results of the test. Team physician Dr. Chris Ahmad was expected to be at the ballpark to examine Judge.

Judge clearly grimaced after making a throw from right field in the seventh inning of Tuesday’s win over the Blue Jays in Toronto. He did not come out of the game, but Boone said Saturday, “It zinged him – it hurt.”

Judge was the designated hitter on Wednesday and, following the club’s Thursday off was again in right field for Friday’s loss to Philadelphia. But the discomfort was there again whenever he threw the ball.

“Last night he was really dealing with it. He couldn’t really throw well from the outfield,” Boone said. “I’m obviously concerned but again, we’ll wait and see.”

Asked if he fears the injury is to Judge’s ulnar collateral ligament – an injury most often associated with pitchers getting Tommy John surgery – Boone replied, “I don’t know.”

“We want to get our hands around exactly what we’re dealing with,” he added.

Judge is having another spectacular season that has him in contention for another MVP Award. He was batting .342 with 37 home runs and 85 RBI entering Saturday.

Despite experiencing the discomfort while throwing, Judge hadn’t been out of the lineup until Saturday.

Boone was asked if Judge is experiencing any discomfort swinging a bat and replied, “I don’t know how much (it’s) there. More about throwing (Friday night). He couldn’t really get the ball in very well.”

Boone didn’t want to speculate about the what it would mean for the team if Judge were to miss significant time.

If playing the field is the only issue, that creates a serious problem for the Yankees. Giancarlo Stanton is the designated hitter when Judge is in the outfield and it would be difficult to have both sluggers only capable of playing DH.

“Hopefully it’s something that’s manageable and we can get through,” Boone said.
