Mariners starting pitcher James Paxton is slated to undergo an MRI Wednesday to determine the severity of the lat strain behind his left shoulder that forced him from Tuesday's start against the Angels.
The Mariners seem more concerned about the injury than does Paxton at this stage, per MLB.com.
"In the fifth inning there, the last batter, I just felt a little tweak," Paxton said. "I felt fine between innings, so I didn't think it was going to be anything. I threw those cutters to the first hitter (Kole) Calhoun, and that was fine. I just felt it again when I threw the fastball to (Mike) Trout.
"It's just a little strain. I'm going to go get an MRI to see what exactly is going on in there, but I just want to be careful right now. My strength is still good, they said, so I just want to get it checked out."
