Mariners pitcher Felix Hernandez was scheduled to undergo an MRI on Tuesday after experiencing discomfort in “his lat area and the back of his shoulder,” Mariners manager Scott Servais said.
Hernandez, who has been on the injured list with a Grade 1 lat strain, pitched 2 1/3 innings with Class AAA Tacoma on a rehab start Friday before being pulled from the game with what was described as shoulder fatigue.
Hernandez was scheduled to throw 50 to 60 pitches, but left the game after throwing 31.
“It’s concerning enough that we’ll take new images of that area and try to figure out what is going on,” Servais said.
