The Mariners have activated right-hander Brandon Brennan from the 45-day injured list, the team announced. In corresponding moves, righty Jimmy Yacabonis was designated for assignment and right-hander Seth Frankoff was optioned to the team’s alternate training site.
Brennan only pitched in one game before a left oblique strain sent him to the IL on August 2. The righty will get a bit of time left to try and build on a 2019 rookie season that saw Brennan post a 4.56 ERA, 1.96 K/BB, and 8.9 K/9 over 47 1/3 innings for Seattle. The results were solid enough to make Brennan look like a nice pickup for the M’s after he was selected out of the Rockies organization in the 2018 Rule 5 Draft.
Seattle acquired Yacabonis from the Padres in August, and the right-hander appeared in two games for the Mariners (allowing one run in 2 1/3 innings). After spending his entire pro career in the Orioles organization, Yacabonis inked a minor league deal with the Padres in the offseason and now could potentially be joining his third different team of 2020 if he is claimed on DFA waivers. Yacabonis offers some innings-eating length as a swingman, though he has only a 5.71 ERA over 104 career frames in the majors.
