"Obviously very excited for Blake," Cash said. "For Matt, I think everybody understands where our bullpen's at, and he's going to go in there and be used as a weapon."
A corresponding roster move hasn't been made yet and will likely be announced before Thursday's game. Snell made his first career start on April 23 at Yankee Stadium, and allowed one run over five innings. He's coming off a 13-strikeout performance in his last start for Triple-A Durham on Friday.
The Rays' bullpen has been taxed coming into Sunday, with relievers Alex Colome, Xavier Cedeno and Erasmo Ramirez each pitching six times over a nine-day stretch. Andriese will be able to eat innings, but he said he had "mixed feelings" about the move.
"It's going to be good for our team," Andriese. "We've had some bullpen struggles as of late. I'm just going to take the same mentality as I've had in the starting rotation."
