Corbin Martin’s changeup has some otherworldly armside run. It sits at 87 and almost looks like a screwball. That said, it was very hit-or-miss. It was his best pitch when it came to whiffs, but also allowed a .555 wOBA. So, when it got hit, it got hit hard.
Martin throws a hard curve that sits between 83-84 mph with less than average break. He snapped off the curve 19% of the time last year, and dropped it in for a called strike more than any of his other pitches. It was more of a ground ball machine for him than a strikeout pitch.
Martin’s four-seamer comes in hot, sitting at 95 mph during his 2019 cup of coffee with good ride to it, typical of any Astros’ pitcher. Despite the velo and ride, his fastball was only average in terms of missing bats. With a 19% BB rate, he could use a little refining of the command on his main offering (63% usage).
Martin’s slider was his least-used pitch during his short stint in 2019 (8%). Much like his curve, it comes in harder than normal and doesn’t have much depth. That said, it mirrors his changeup more than anything. Both pitches get similar depth with similar velocity, but break in opposite directions. He might benefit from sequencing these together.
