NEW YORK -- A key member of the Orioles’ rotation has gone down due to injury.

exited Tuesday night’s game vs. the Mets at Citi Field after getting hit by a 105.1 mph liner off the bat of Bo Bichette during the fifth inning. The 27-year-old right-hander was struck by the ball on the back of his right elbow.

Baz showed visible pain, as he kneeled on the back of the mound and held his elbow. Manager Craig Albernaz and assistant athletic trainer Ben Fraser came out to check on Baz, who attempted to throw one warmup pitch that sailed to the backstop before his departure.

The Mets scored one run in each of the first three innings against Baz and had a 3-2 lead at the time of his exit. The righty gave up seven hits over four-plus frames in the 68-pitch outing.

Baz has a 4.11 ERA in 173 innings over 30 starts during his first season with Baltimore. He was acquired in a trade with Tampa Bay last Dec. 19 and then signed a five-year, $68 million extension with the O’s on March 27 prior to his debut for the team.

The severity of Baz’s injury is not yet known.
