Morrison has been mostly injured and ineffective for the past two seasons, hitting just .236 with a .708 OPS in 178 total games, but he has good plate discipline and 25-homer power from the left side of the plate and is still just 26 years old.
Hart and Morrison both have plenty of previous outfield experience, so the Mariners will divvy up the first base, left field, and designated hitter playing time three ways among Hart, Morrison, and Justin Smoak. And whatever chance there was of Kendrys Morales re-signing with Seattle is now gone.
Capps was the Mariners’ third-round pick in 2011 and has struggled in the majors so far with a 5.04 ERA, but he throws in the high-90s and has racked up 94 strikeouts in 84 innings after posting awesome numbers in the minors. He’s also 23 years old, so there’s definitely plenty of upside for a late-inning bullpen role in Miami.
