The Tampa Bay Rays have acquired reliever Steve Cishek from the Seattle Mariners in exchange for reliever Erasmo Ramirez.
Cishek, an impending free agent, will work in a setup role for Tampa Bay. The 31-year-old right-hander was sidelined to start the season due to offseason hip surgery, but he's been great, twirling a 3.15 ERA, 1.00 WHIP, and 18.8 strikeout percentage across 20 innings (23 appearances).
numberFire's models project Cishek to record a 3.46 ERA, 1.15 WHIP, and 20.8 strikeout percentage across 13 remaining innings this year.
