The Mariners recalled Davila from Triple-A Tacoma on Tuesday.
Davila will return to the big leagues as the roster replacement for Cooper Criswell (shoulder), who landed on the 15-day injured list Tuesday. Davila has fired 7.1 shutout innings with the Mariners this season, though he's done so while posting a 4:6 K:BB. He'll likely be limited to middle-relief duty while with Seattle.
