After he made just five starts at High-A toward the end of his breakout 2021 campaign, this season the Marlins sent the 6-foot-9, 19-year-old Pérez to Double-A Pensacola, where he has been a buzzsaw, striking out 34.2% of opposing hitters while only walking 5.4% across just north of 50 innings. Over the last year, Pérez has added about 30 pounds, experienced a two-tick fastball velocity bump, and incorporated a second, harder breaking ball that has become his primary non-fastball weapon. After sitting 94-95 mph last year (Pérez was a 50 FV prospect ranked 67th in the offseason), he’s now parked in the 96-98 mph range for entire starts, and his hardest sliders (in the 85-87 mph range) are nearly 10 mph harder than his average curveball was in 2021 (77 mph). While he’s been uniformly dominant in the minors, Pérez’s stuff has now hit a different gear.
Even more precocious than Pérez’s velocity is his fastball command, which is absurd for a 19-year-old, let alone one who throws this hard and is also this size. He shows bend and balance in his lower half as he propels himself way down the mound and releases on the doorstep of the batter’s box, making hitters extremely uncomfortable. Though he doesn’t throw the pitch a ton, his changeup feel is also very good, and currently more consistent than his feel for his new slider, though I expect that will come. Pérez’s fastball shape operates to the east and west of the zone. His heater is only generating about a 14% swinging strike rate, per Synergy Sports, which is above the big league average but not elite. There are still some things to work on here, but Pérez is younger now than Trevor Rogers was on the day he was drafted, and the fact that Pérez has made relevant adjustments this year and continues to dominate while implementing them is remarkable.
Within the last few weeks, scouts who have seen Pérez (one who I happened to be at a game with, as well as a newer source of mine) have said they can make the argument that he’s the best pitching prospect in baseball right now because the other few in that discussion (for me, Grayson Rodriguez, who has a strained lat; Shane Baz, who had arthroscopic surgery from which he recently returned, arm strength intact; and Daniel Espino, currently in a pretty long layoff for a knee issue) have all been hurt recently.
