Scouting Report
Delzine has shot up prospect rankings this season, as he went unlisted on not just the TalkSox list but nearly every major prospect ranking coming into 2026. That quickly changed once the FCL season began in early May, as he has put on a show with his pitching. A strong, tall right-hander, Delzine stands at a towering 6-foot-5 on the mound and still has room to grow as he enters his late teens (he won’t turn 19 until 2027). In his first taste of stateside baseball, Delzine has dominated in his seven appearances. Tossing 27 1/3 innings, he’s allowed just seven runs, six of them earned, while striking out 32 batters.
Delzine, who signed with the Red Sox in January of 2025, is already viewed as a high-upside arm throughout the system thanks to his size and athleticism that he’s shown during his time in Florida. Even before this season, the Red Sox were high on him, as the right-hander received the largest bonus of any pitcher signed by the Red Sox in their 2025 international free agent class.
On the mound, Delzine starts on the first base side of the rubber before throwing from a three-quarters arm slot. With a high leg kick and a quick arm, Delzine has shown an ability to repeat his delivery early on in his career. Thanks to his large body and the belief he’ll only grow more, Delzine has the body of a starter and will be developed as such.
He already has a four-pitch arsenal, with three of them already in game-ready form. His best pitch is his fastball, while he uses a changeup and curveball to supplement it. Delzine also has a slider, but it’s behind his other two secondaries. The fastball averages around the low-90s, topping out as high as 94 mph at times and is viewed as having room to add velocity as he grows. Despite being his best pitch so far in his career, it might be his changeup that becomes his best pitch in the future thanks to the bat-missing ability it’s already showcasing.
His curveball is one that breaks 11-to-5 and some have said that at its best, it showcases a tight rotation that allows him to bury it down in the zone and can throw it away from right-handed batters. There isn’t much on his slider, as it’s still being developed.
Overall, he’s viewed as a high-upside prospect that should be able to handle the strain of starting games along with having the mental aspect needed due to his competitive nature. Should Delzine develop consistently and avoid injuries, there may be a new arm joining the likes of Eyanson, Witherspoon and Phillips when it comes to the most hype in the system.
