Keith Law has Baldwin as his #27 overall prospect:
Baldwin is such a good defender behind the plate that he’s almost certainly going to be someone’s everyday catcher, and if his raw power keeps showing up in games as it did after a midseason promotion to Triple A, he’s going to make some All-Star teams. He was Atlanta’s third-round pick in 2022 out of Missouri State, where he wasn’t a full-time player until his draft year, and he’s improved substantially as a hitter since entering pro ball, loosening up at the plate to try to get to more of that plus power. He had a slow start in Double A but Atlanta promoted him to Gwinnett in early June, after which he took off, hitting .298/.407/.484 at the higher level with 12 homers in 72 games. He hits the ball extremely hard — his average exit velocity in Triple A was 92 mph, his EV50 was 103, and his 90th percentile EV was 107 — so there’s every reason to think the power is real. He whistles the bat through the zone with excellent bat speed, and even with a pretty high starting position he hasn’t had trouble getting to pitches at the bottom of the strike zone so far. He’s an outstanding blocker and receiver with plus arm strength but just fringy accuracy so far, leading to a career 20 percent caught stealing rate in the minors. A 20-homer catcher with plus defense will rank among the best backstops in the majors, and Baldwin looks like he can be at least that, and probably will debut this year.
