Trout suffering from Costovertebral Dysfunction at T5; back injury that he has to manage and deal with for the rest of his career.
He has control issues (which most with 100 mph do) but he threw two unhittable strikes to the bottom/away corner; if he can do that consistently, he wouldn't even need a secondary pitch.
