Pretty much everything else besides his height is a positive. FanGraphs describes Yamamoto as "reminiscent of peak Zack Greinke" and grades his future value as a 65 on the 20-80 scale, which is a higher grade than that of the current top prospect in the minors, Baltimore Orioles phenom Jackson Holliday. Baseball America went even higher, with a 70 grade for Yamamoto, saying he "projects to be a No. 2 starter (lol) and has a chance to contend for Cy Young Awards."

Yamamoto boasts a deep arsenal of pitches, with four of them graded by BA as above-average. It starts with a mid-90s fastball, followed by a wipeout splitter and a looping curveball. Rounding out the group are a slider and a cutter to keep hitters guessing, and all of the pitches are elevated by consistent command.

Of course he needs to switch from pitching once a week to once every 5-6 days...but with 15-20% fewer pitches in the US.
