The issue I have with the reported Greene's ceiling is that it is "calculated" based on his fastball and "athleticism". The last is not a huge difference maker in baseball, esp. for pitchers.I'd put mechanics over athleticism all day (and night.)His mechanics are dubious at this point.Same with a fastball.Heard some reports that it "can use a bit more movement".If that is the case, it is pretty scary, because, what you can blow past a Private Religious High School player, you likely cannot blow by an average A class player. And looking at Greene's stats he is "dominant" (48 K per 106 batters faced, 12.2 per 9), but not dominant (18 H + 4 BB per 28 IP,= 0.785 WHIP,) based on the level of competition.
Hunter excelled in national showcases against the top HS talent in the country, he was also on Team USA 18U so he's played against the highest levels of competition available to a "Private Religious High School player" and was dominant. His HS coach also treated him with kid gloves (as he should), never extending him long into games, finishing his pitching season early, so his regular HS season stats are pretty much meaningless in the scouting world.
Per BA on Greene:
He has an exceptionally athletic delivery with an easy finish, and he pitched mostly at 95-99 throughout the spring of his senior season, with his fastball reaching as high as 102 mph for some scouts, while others had him topping out at 101. He was throwing both a slider and a curveball as a senior, with his slider figuring to be a bigger part of his future. Thrown in the low 80s, the pitch flashes slurvy tilt and earns above-average projections from scouts. He throws all four of his pitches for strikes. Greene has focused on pitching off his fastball and doesn’t have as many reps with his offspeed stuff as a result. He flashes feel for his changeup, which scouts feel comfortable projecting given Greene’s advanced command and athleticism. Greene has massive hands with thick fingers, elements that tend to predict quick changeup growth. Greene was a high-achieving student and scored a 31 on the ACT, a score that ranks among the top three percent of all students taking the test. In the winter prior to his senior spring, he organized a sock drive for the homeless, sending autographed cards of himself to fans who donated socks. Greene was a disciple of Alan Jaeger at seven years old and has specific training techniques that he’s reluctant to stray from at the next level. He long tosses prior to games and actively practices yoga to keep himself flexible and present.
