Heading into this season, Luis Severino was widely regarded as one of the better pitching prospects in the Yankees system, and while that may not be saying too much, it was something. Baseball Prospectus (subscription required) named him as a prospect on the rise, and John Sickels saw him as the best Yankees pitching prospect this side of Masahiro Tanaka. He did not, however, receive any love on the national level (with 'love' defined as 'something resembling consideration on any non-Yankees specific prospect list'). And now, Severino is regarded as one of the best pitching prospects in all of baseball.
Earlier today, both Baseball America and Baseball Prospectus (subscription required) released their mid-season top-50 lists, ranking Severino 34th and 48th, respectively. This comes on the strength of Severino dominating at both Low-A (2.79 ERA, 2.77 FIP, 9.3 K/9, 4.7 K/BB) and High-A (1.62 ERA, 1.66 FIP, 10.8 K/9, 5.0 K/BB), as he sits in the mid-90s with his fastball, and continues to hone his secondary pitches.
With Gary Sanchez continuing to butt heads with management and Mason Williams forgetting how to hit, it seems there is a new crown jewel in the Yankees system. Long may he shine.
