When you look at the top four options out of the Seattle Mariners bullpen last season, it was tough to find many combos better than Andrés Muñoz, Matt Brash, Eduard Bazardo and Gabe Speier. However, the M's still could have used more quality depth relief options, especially when injuries meant an over-reliance on the likes of Bazardo, which ultimately proved costly in the playoffs.
The Mariners took care of this to a certain extent with the offseason trade for Jose A. Ferrer from the Washington Nationals, although it did mean giving up top catching prospect Harry Ford.
