• 7/5: Martin has Tommy John, out for season
During his college career, Martin alternated inconsistency with flashes of dominance while shuttling between roles at Texas A&M with dominating as a reliever in summer leagues. He flashed first-round stuff at times but was available to the Astros in the second round of the 2017 Draft with a pick they received from the Cardinals as punishment for a hacking scandal. He reached Double-A a month into his first full pro season and Houston a month into his second, though he got hurt after returning to the Minors and had Tommy John surgery in July. Less than a month removed from surgery, Martin was dealt to Arizona along with Seth Beer, J.B. Bukauskas and Josh Rojas for Zack Greinke.
Martin's arsenal begins with a 92-95 mph fastball that hits 97 with running action, and he has reached the upper 90s while working in relief. He can miss bats with each of his breaking balls, with his slider showing more flashes of becoming a true plus offering than his curveball. His changeup continues to improve as he uses it more often and helped make him slightly more effective against lefties than righties in 2018.
Though Martin had trouble sticking in the Aggies rotation, he has looked like a slam-dunk starter since signing for a below-slot $1 million. He's doing a better job of commanding his fastball and throwing strikes with his entire repertoire. He has the athleticism to repeat his delivery and maintain his stuff into the late innings, enhancing his chances of slotting into the middle of a big league rotation.
