SEATTLE -- The Mariners acquired right-handed reliever Jason Davis from the Indians on Sunday for a player to be named.
Davis is expected to join the Mariners prior to Tuesday night's series opener against the Angels at Safeco Field.
"We think Davis can help us in the bullpen," Mariners general manager Bill Bavasi said in a statement. "He was very effective last year after being moved full-time to the bullpen, and his ability to work long or short should give [manager Mike Hargrove] additional options."
Davis conceivably could replace Julio Mateo in the Seattle bullpen.
Mateo, a six-year veteran, is currently suspended without pay for an off-the-field incident last weekend in New York.
Davis has an 18-22 career record with a 4.69 ERA in 114 Major League games. He was 0-0 with a 4.76 ERA in eight relief appearances this season for the Indians.
The Mariners are expected to activate starting pitcher Felix Hernandez from the 15-day disabled list on Friday, possibly returning right-hander Ryan Rowland-Smith back to Triple-A Tacoma. The Mariners would also have to create a roster spot for Davis.
