SCOTTSDALE, Ariz. -- The Mariners finalized their 25-man roster on Saturday as left-handed reliever Tyler Olson was selected from Triple-A Tacoma and shortstop Chris Taylor went on the 15-day disabled list.
Olson, a 25-year-old out of Spokane, Wash., came to camp as a non-roster invitee after pitching Double-A ball last year. But the former starter was outstanding from start to finish in his first Major League camp as he didn't allow an earned run in 12 2/3 innings over 10 appearances.
Olson had 15 strikeouts and no walks while giving up eight hits, earning him the final spot in the bullpen as the second left-hander behind veteran Charlie Furbush. The Mariners waited until after their final spring game on Saturday to officially add Olson to their Major League roster.
Taylor was placed on the disabled list with a fractured bone in his right wrist, an injury that occurred when he was hit by a pitch in mid-March. Taylor's disabled-list stint is retroactive to March 27.
The moves set the Mariners' Opening Day roster at 25 players. Seattle opens the season Monday at 1:10 p.m. PT against the Angels at Safeco Field.
Seattle's 25-man roster is:
Starting pitchers: Felix Hernandez, James Paxton, Hisashi Iwakuma, J.A. Happ, Taijuan Walker
Relievers: Fernando Rodney, Tom Wilhelmsen, Furbush, Danny Farquhar, Yoervis Medina, Carson Smith, Olson
Catchers: Mike Zunino, Jesus Sucre
Infielders: Logan Morrison, Robinson Cano, Brad Miller, Kyle Seager, Willie Bloomquist
Outfielders: Dustin Ackley, Austin Jackson, Seth Smith, Rickie Weeks, Justin Ruggiano, Nelson Cruz
