Robbie Ray will have surgery to repair the flexor tendon in his pitching elbow and will miss the rest of the season.

The Seattle Mariners made the announcement on Wednesday night.

"Tough news," Scott Servais said. "Obviously, it's really hard for Robbie. He's a really good competitor and we miss not only what he does every fifth day when he takes the ball, but certainly being a really good teammate and having a guy around that we can lean on."

Ray, in the second season of a $115 million, five-year contract, was injured in his season debut on March 31.

"In the second inning it felt a little tight, but it didn't seem out of the ordinary," he 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."
