A 2011 early-round pick by the Cubs, Zych was famously traded to the Mariners for exactly $1. He always showed tremendous strikeout upside during his Mariners tenure. Across 32 innings during the 2015-2016 seasons, he owned an impressive 12.66 K/9. However, that fell to a much more average 7.75 K/9 last season in 40 2/3 innings.
That Zych has only managed 72 2/3 innings since being promoted in September of 2015 might speak more clearly to the reason for his release. The righty has struggled with shoulder and arm injuries throughout his career, and as such he’s had quite a bit of trouble staying on the field.
If Zych can regain his health, however, it’s not hard to see an MLB team bringing him into the fold. His strikeout upside and ground ball rate (just under 50% for his career) are both reasons to believe that the 27-year-old could contribute at the back end of a major league bullpen again.
