School: Duke
Commit/Drafted: Never Drafted
Age At Draft: 21.6
BA Grade: 55/Extreme
Tools: Fastball: 60. Slider: 60. Changeup: 50. Control: 40.

Santucci flashed big-time upside in each of his first two seasons at Duke, but he was limited as a hybrid starter/reliever as a freshman and then started just seven games in 2023 thanks to a season-ending elbow surgery. He finally worked a complete season as a starter for the Blue Devils in 2024, when he served as the team’s Friday night ace and posted a 3.41 ERA in 13 starts and 58 innings with a 35% strikeout rate and 14% walk rate. Santucci was one of the most electric pitchers in the country through the first three weeks of the season but began struggling with control as he entered Atlantic Coast Conference play. He also dealt with a rib injury in May. He’s a strong and athletic southpaw with a 6-foot-2, 205-pound frame and quality three-pitch mix. Santucci’s fastball sits 93-95 mph, touches 97 and has above-average riding life and bat-missing qualities, but his command of the pitch leaves a lot to be desired. He has better feel for a mid-80s slider that features snappy two-plane break at its best, but he would also overthrow the pitch at times to find the strike zone, which meant hitters could find success sitting on it. His upper-80s changeup has late tumbling action and fade and above-average potential, but he threw it just 9% of the time this spring. Santucci’s below-average control creates reliever risk, but he offers first-round stuff for a team that thinks it can help him improve his command.

Track Record: Like fellow top Mets prospects Nolan McLean and Carson Benge, Santucci has a background as a two-way player. He played both ways as a Duke freshman before committing to the mound and becoming the Mets’ second-round pick in 2024. Santucci got off to a rough start at High-A Brooklyn in 2025—8.14 ERA, seven home runs in six starts—before righting the ship and cruising to Double-A Binghamton in July. He pitched to a 1.95 ERA and .186 opponent average with two home runs allowed in his final 20 starts, striking out 30% of batters. He pitched effectively in the Eastern League playoffs.

Scouting Report: Santucci throws his slider more than his four-seam fastball—an approach that works because he commands his powerful, deceptive slider. It averages 87 mph and maxes out near 93 with a lot of vertical drop. He can locate the pitch for strikes or bury it late in the count. It looks like a fastball out of the hand before falling off the table. Santucci’s fastballs averages 94 mph and tops out at 97 with enough ride and extension in his delivery to help the pitch play up. He began incorporating a low-80s curveball to give him a change-of-pace pitch. His changeup is in the development stage, and he doesn’t throw it often. He walked 14% of batters as a college junior, but he improved his control dramatically by focusing on throwing to the middle of the plate and letting the action on his pitches take over.

The Future: Santucci stands out in a Mets system that has largely been devoid of lefthanders for the past decade outside of David Peterson and Steven Matz. Santucci’s platoon-neutral slider, quality velocity and improved strike-throwing give him a real shot to become a No. 3 or 4 big league starter, just like Peterson and Matz. He will be ready for Triple-A in short order.

The Future: Fastball: 60 | Curveball: 50 | Slider: 65 | Changeup: 40 | Control: 50.
BA Grade/Risk: 55/Extreme.

Track Record: Santucci was a standout two-way player in high school at Phillips Academy in Massachusetts, where he was teammates with current Marlins prospect Thomas White. Santucci continued as a lefthander/outfielder as a Duke freshman before switching to the mound full time in 2023 and working exclusively as a starter. He made just seven starts as a sophomore after having elbow surgery. Santucci logged a career-high 58 innings as the Blue Devils’ Friday night starter in 2024—he missed a month with a rib injury—and recorded high rates for both strikeouts (35%) and walks (14%). The Mets drafted Santucci in the second round and signed him for slot value of $2,031,700.

Scouting Report: Santucci follows Brandon Sproat in 2023 and Blade Tidwell in 2022 as power college starters drafted by the Mets in the second round after they slipped down the board. Santucci is a physically developed, 6-foot-2 lefthander with a strong fastball/slider foundation. His fastball sits 93-95 mph and touches 97 with above-average riding life. Throwing strikes with his four-seamer was a major challenge in college and contributed to walks and high pitch counts. Santucci’s 83-85 mph slider is an equalizer as a platoon-neutral weapon with late, two-plane break. He has had some success with a high-80s changeup but throws in sparingly. Making the proper adjustments in pro ball will be essential to iron out Santucci’s well below-average control. The Mets are toying with the idea of adding a sinker or cutter to his repertoire to seek more early-count, weak contact and avoid deep counts.

The Future: Santucci’s fastball and slider give him potential major league weapons. Now, it’s a matter of finding the right complementary pitches and control to tie the package together. Just as it did for Sproat and Tidwell, his first full season begins at High-A Brooklyn in 2025.

Scouting Grades: Fastball: 60 | Slider: 65 | Changeup: 40 | Control: 45.
