The Mariners have had a couple of setbacks with their relievers this spring, as Matt Brash and Gregory Santos have been dealing with arm injuries. This has put the start of each of their seasons in doubt. Going into this season with two potent arms on the injured list is unfortunate, however, the good news is the Mariners have done a good job in recent years of developing unknown relievers. Finding hidden gems in both their minor league system as well as free agency to build strong bullpens.
This year, the Mariners must find new arms to fill out the back end of their bullpen if Santos and Brash miss extended time due to injury. Those pitchers have had opportunities to prove themselves during Spring Training. Given the Mariners' current injury situation, multiple Spring Training invites could have a chance to make the Opening Day roster.
Since the Mariners traded Justin Topa and Isaiah Campbell this past winter, they face a unique challenge. Seattle needs to replace the two pitchers they traded and try to find pitchers who can fill the void while Santos and Brash are injured. The Mariners still have relievers Andres Munoz, Gabe Speier, and Tayler Saucedo from last year's team. They will need to find additional relievers to fill out the rest of their bullpen following injuries and trades this off-season.
