The Seattle Mariners have placed Robbie Ray on the 15-day injured list with a left flexor strain.

Ray had a rocky first start on Friday night in a 9-4 loss to the Cleveland Guardians. Ray failed to make it through the fourth inning, issued five walks and struggled badly with his control.

"In the second inning it felt a little tight, but it didn't seem out of the ordinary," Ray said. "It was a cold night, I just thought maybe it took me a while to get loose in that second inning. I didn't really think that much about it, but after that my arm started to tighten up a good amount."

Scott Servais said Ray had an MRI on Saturday that showed a Grade 1 strain. Ray won't throw for two weeks and will be reevaluated.
