I’ve seen quite a few pitchers already this fall with some MLB potential, but none have been more impressive than 21-year-old Greene. The first thing you notice is the ideal, athletic pitcher’s frame at 6’3″ which still shows some projection. He’s listed at 185 pounds, and while I do not know how accurate that is, it’s clear that there is still some room to add lean muscle weight. It’s hard not to take a look at Greene and not dream of what he can become.

But Greene isn’t just projection. There is plenty to like about his present stuff, athleticism, and delivery. Greene already shows a double-plus to elite fastball at 96-to-98 mph (T99) from an easy, clean delivery with good downhill plane. He adds a hard 86-to-87 mph slider with good tilt that one evaluator rated as a plus offering. The changeup also has the makings of an above-average pitch. He throws it with good arm speed at 84-to-85 mph and the pitch shows some nice fade, making it a potential weapon against opposite-side hitters.

Greene has added some strength over the past season, and he was able to maintain the increased velocity over his 2.1 innings on Saturday, never once dropping below 96 mph. Whether he is able to maintain that velocity deeper into the game is a question he will need to answer as he continues to develop and mature physically. – John Arguello
