Gearrin will serve as the opener for Monday's game against the Astros, Greg Johns of MLB.com reports. Gearrin will likely pitch one or two innings before giving way to left-hander Wade LeBlanc, who is expected to cover the majority of innings Monday. In 26 appearances this season (all in relief), Gearrin owns a 3.22 ERA, 1.34 WHIP and 27:13 K:BB in 22.1 innings.
Gearrin has generated six consecutive scoreless appearances to open May and owns an 0-1 record, a 3.63 ERA, a 1.50 WHIP and six holds across 17.1 innings this season. The right-hander had his share of hiccups in April, a month in which he posted a 5.59 ERA by allowing at least one earned run in four of 11 appearances. However, he's mostly evened things out in the current month, lowering his ERA to 4.85 on the strength of his aforementioned string of scoreless efforts.
Hunter Strickland is expected to receive an MRI after experiencing shoulder tightness Friday, Ryan Divish of The Seattle Times reports, and Gearrin is on the short list of possible replacements for the ninth inning. Anthony Swarzak (shoulder) and Shawn Armstrong (oblique) are hurt too, though Swarzak seems to be inching close to a return. If the M's need someone to step in for Strickland in the interim, it could very well be Gearrin, who split time between three clubs last year. He doesn't throw hard but can throw a pretty wicked slider. The right-hander has leaned on the breaking stuff more often early on this season, to impressive results in the small sample (one hit allowed, one walk, three strikeouts against 10 batters faced). Matt Festa and lefty Roenis Elias could also be in the mix.
Gearrin (triceps) signed a one-year contract with the Mariners on Thursday, Ryan Divish of The Seattle Times reports. Gearrin spent time in three organizations in 2018, producing a 3.77 ERA and a 53:21 K:BB across 57.1 innings. He's not a flashy pitcher as his modest strikeout numbers suggest, but he figures to be a staple of the Mariners' bullpen as a middle reliever throughout the season.
Gearrin has been unavailable due to a triceps issue, Jane Lee of MLB.com reports. Gearrin hasn't pitched since Sept. 18. He's allowed four runs in six innings since heading to Oakland in late August. The full extent of his injury is not yet clear.
