The Mariners are reworking their bullpen: Yoervis Medina and Tyler Olson were shipped out to AAA Tacoma Sunday following a four-game sweep in Houston by the Astros. The Mariners made no announcement about roster replacements, but likely candidates are veteran relievers Joe Beimel and Mark Lowe.
They would join the Mariners in Anaheim, where they begin a three-game series Monday against the Angels.
Medina, 26, has a 3.00 ERA and 1.50 WHIP in 12 innings this season. He’s made 141 appearances since joining the Mariners in 2013.
Olson was a big story coming out of spring. A 25-year-old rookie from Spokane who pitched four years for Gonzaga, he has a 5.40 ERA and 2.10 WHIP in 13.1 innings. He vaulted over Triple A after success at Double A, so playing in Tacoma is a first.
Lefthander Beimel, 38, and righthander Lowe, 31, have been in the Mariners pen in previous seasons. Both were signed to minor league contracts prior to the season.
