Gabe

Speier

Muñoz came in to close out a 6-5 lead in the 10th, but immediately gave up a run on a single to Jacob Wilson. The run was unearned because it was the inherited runner to open the inning, but it still causes him to blow his first save. This could have been worse as Muñoz loaded the bases with nobody out, but pulled off a magic trick by not allowing another run while striking out the side. There’s a good chance he won’t be available for Tuesday’s contest as he needed 28 pitches to get through Monday’s action. That could put Matt Brash or Gabe Speier in position to vulture a save tomorrow.

Speier will give the Mariners an extra left-hander in the bullpen and has been a disappointment with a 5.66 ERA in his 20 2/3 innings. Emerson Hancock heads to Triple-A to make room.

The 29-year-old southpaw has appeared in 26 games for the Mariners this season, posting a disappointing 5.66 ERA, 1.36 WHIP and a 28/12 K/BB ratio over 20 2/3 innings. He’ll continue to function as extra bullpen depth for the Mariners at the Triple-A level.

With Yimi Garcia heading to the injured list on Friday, Speier will get another opportunity to work out of the bullpen at the big-league level. Speier holds a 5.95 ERA, 1.42 WHIP and a 26/12 K/BB ratio over 19 2/3 innings in 25 appearances for the Mariners this season.

Speier got off to a great start for the Mariners this season, but he started struggling in May and then went on the IL with a rotator cuff strain. He had made just three appearances since returning, allowing two runs in 3 1/3 innings. He’ll likely be back before long.

Speier, 29, has been sidelined since the end of May with a left rotator cuff strain. Prior to landing on the shelf, he struggled badly through 22 outings — posting a 6.06 ERA, 1,47 WHIP and a 22/10 K/BB ratio over his 16 1/3 frames. Mike Baumann was designated for assignment in a corresponding move.

Speier is working his way back from a left rotator cuff strain that sent him to the injured list back in late May. The 29-year-old southpaw’s return should provide a lift to Seattle’s middle relief depth.

It’s not immediately clear how long the Mariners think the 29-year-old southpaw will be shelved for. Speier has struggled mightily in 22 appearances out of the M’s bullpen this season, posting a 6.06 ERA, 1.47 WHIP and a 22/10 K/BB ratio across 16 1/3 innings of work. Collin Snider was recalled from Triple-A Tacoma in a corresponding move on Saturday.

The 28-year-old was called upon to face the heart of the Astros lineup. He struck out Yordan Alvarez and Yainer Diaz before Chaz McCormick reached on a grounder to Dylan Moore at short. He tossed four more pitches and got Jon Singleton to fly out to Julio Rodríguez in center field. Speier has been excellent this season, posting a 3.16 ERA across 53 appearances.

He’s taking the roster spot vacated by injured left-hander Robbie Ray (flexor strain). It seems likely that Speier will only be around as an extra bullpen arm for a few days until the Mariners figure out how to replace Ray in their starting rotation.
