Griffin was No. 1 on our ranking of the top 50 MLB prospects released last week. The 19-year-old shortstop is the best player in the minor leagues, and there’s a sizable gap between him and the rest of the competition. Tigers third baseman Kevin McGonigle ranked No. 2 on our list, and he’s slashing .364/.440/.545 with a 187 wRC+ in his first week of big league action. Griffin could have a similar impact, despite being two years younger than McGonigle.

Leading up to the 2024 draft, Griffin had the best all-around tools available as a prep infielder out of Jackson Preparatory School in Flowood, Miss. He had reclassified from the ‘25 class to ‘24, and that could have hurt his stock a bit. Pittsburgh landed him with the No. 9 pick and gave him a $6.53 million bonus. It was clearly the right decision.

Griffin is an elite athlete at 6’3” and 222 pounds, and he could play short or center. The Pirates are going to hand him the starting shortstop role, but given Oneil Cruz’s issues in the outfield, his newest teammate may be more valuable there long term. Griffin oozes star power and showed that during the spring when he blasted four home runs, though his OPS dropped to .749 as March went on.

The 2025 campaign was Griffin’s first taste of professional baseball, and he was outstanding. He began the year in A ball, and finished it with 21 games at Double A. In that time, he hit .333 with a .415 on-base percentage while slugging .527. He had 21 home runs, 23 doubles, four triples, 94 RBIs and 65 stolen bases. His wRC+ of 165 was eye-popping for a 19-year-old.

After the spring, Griffin was sent to Triple A Indianapolis, and it only took five games for the franchise to bring him back up. In Indy he went 7-for-16 at the plate with three doubles, five walks, three stolen bases and four strikeouts. He produced a 1.196 OPS and a wRC+ of 238. So, yeah, we’ve seen all we need to see of him at that level.

Aside from big raw power at the plate that comes easily, Griffin has incredibly quick hands and has improved his swing decisions since his high school days. He gets to the ball quickly and is still improving on his pitch recognition. When he puts the ball in play, his elite speed is always a factor. He should be able to routinely take extra bases, and he stole 65 bases in 78 attempts in 2025.

No matter where he ends up in the field, he’ll be excellent. He has good footwork and hands at short, while his speed would provide outstanding range in the outfield. When he gets the ball, he has an absolute cannon of an arm. On top of all of that, Griffin’s makeup is off-the-charts. He’s a hard worker who is constantly improving. There’s a reason the Pirates are attempting to lock him up with a record-breaking deal.

Given that he won’t turn 20 until late April, it’s possible Griffin will take some time to adjust to the grind of the MLB season, but the kid is going to be a star.

Paul Skenes is the Pirates’ biggest star, but Griffin is poised to give him a run for his money. With those two, plus Bubba Chandler on the mound, Pittsburgh has an elite young core moving forward.
