After experiencing the high of a no-hitter last week, Yankees pitcher Corey Kluber lasted just three innings in his most recent start on Tuesday.
The right-hander left his start against the Blue Jays due to tightness in his right shoulder, according to the Yankees. He is expected to undergo an MRI on Wednesday.
The latest development was the risk the Yankees were taking when signing the 35-year-old, who entered the season having made just eight starts over the last two years.
He pitched just one inning last season with the Texas Rangers before he was shut down after sustaining a Grade 2 tear of the teres muscle in his right shoulder.
Kluber entered Tuesday with a 2.86 ERA but allowed two runs on two hits and three walks while striking out five in three innings pitched against the Blue Jays.
