The Mariners could use more bullpen depth and while not a front runner per se, they've been mentioned as a potential landing spot for A's reliever Mason Miller.
We're now just 10 days away from one of the most important trade deadlines of Jerry Dipoto's tenure with the Seattle Mariners. This is a team which needs to (at least) qualify for the playoffs and there are several needs, including adding quality depth to the bullpen.
While the bullpen includes the likes of Andrés Muñoz, Matt Brash and Gabe Speier, it ranks just 13th in the majors in ERA, as well as 18th in WHIP, batting average and strikeouts.
