Scouting Report

Scouting grades: Hit: 45 | Power: 55 | Run: 40 | Arm: 50 | Field: 55 | Overall: 45

DeMartini was part of an upsurge of hitting talent at Virginia Tech and put up numbers for three years with the Hokies. After a shoulder injury limited him in 2023 and required labrum surgery after the season, he returned to hit 21 homers last spring, though with the power uptick came a regression in his overall approach. The Phillies liked the offensive potential enough to take him in the fourth round, and while it was brief, he impressed during his pro debut with Single-A Clearwater, posting a .315/.385/.478 line over 104 plate appearances.

While DeMartini has a power-over-hit profile from the left side of the plate, he has a good swing, doesn’t chase a ton and can hit the ball very hard. His strikeout rate jumped back up in his last year in college, but the Phillies were thrilled at how he integrated data and made adjustments during his pro debut. When told that his in-zone contact was particularly low in the spring, he turned that around with an in-zone contact rate of 87.6 percent with Clearwater, giving confidence that he’ll be able to get to his power more consistently, while a healthy shoulder should allow him to repeat his swing path.

Perhaps the biggest surprise was how good DeMartini looked defensively. While the industry consensus may have been that he was an average defender at the hot corner, the Phillies think he has the chance to be at least plus with his glove and their defensive coordinator thought he had the chops to play shortstop. He may not have the quickness to stay there long-term, but how he showed on both sides of the ball made him the surprise of the Draft class.

Virginia Tech has built a recent reputation of developing hitters who go early in the Draft, with six players taken in the top five rounds over the previous two years. DeMartini had been part of the offensive upswing since his freshman year in ’22, posting an OPS over 1.000 in his first two seasons. A shoulder injury forced him to a DH role for much of the 2023 season, and surgery to repair his labrum kept him out of fall action. He returned to the lineup and the field in the spring, and while the power returned, so did some concerns about his approach. But the Phillies saw enough offensive upside to make him the seventh Hokie to go in the top five rounds in the past three years, signing for full slot as a fourth-round pick.

DeMartini is a compact and strong left-handed hitter who looks to do damage. He has a power-over-hit profile with plenty of bat speed to drive the ball and extra-base authority to all fields. After striking out in 25.2 percent of his plate appearances in 2022, he trimmed that to 17.1 percent as a sophomore by cutting his chase rate on breaking stuff, seeing a lot of pitches and upping his walk rate. He still drew free passes as a junior, but the K rate jumped back up, with some wondering whether the repaired shoulder had forced a swing change that added holes in his path.

A shortstop in high school, DeMartini moved over to third base at Virginia Tech with fringy footwork and hands. He had plenty of arm for the hot corner before the surgery, but he’ll have to prove his repaired shoulder is 100 percent. A move to left field could be in his future, but it’s the power potential the Phillies were really buying.
