The Mariners did not need much of an introduction to José Suarez. They have seen plenty of him from across the AL West, which makes this waiver claim a little more interesting than a random depth grab. Seattle claimed the former Angels left-hander off waivers from the Braves, adding another arm to a bullpen picture that has already started to feel a little crowded.
