Formerly a member of the class of 2029, Di Maggio reclassified into 2028 when it became very obvious he was too advanced for his age group. A well-balanced profile with an uncommon amount of polish for his level, Di Maggio figures to be a force offensively, with blossoming athletic skills yet to fully determine if his future is in centerfield or right field. And yes, the late, great, Joe DiMaggio is the cousin to Mattis' great grandfather.
As a high school freshman facing pitchers three years older than he, Di Maggio slashed .500/.645/1.024 with 34 walks and just one strikeout at Dos Pueblos. He hit 11 homers, setting a new school record. That sort of dominance is seldom seen from a 15 year old. He parlayed his freshman season into a summer circuit performance that was even better. Across 31 games and over 100 plate appearances in 2026, Di Maggio slashed .447/.592/.684 against even greater competition, including a run with Team USA U15. Di Maggio boasts plus bat-to-ball skills, plus pitch selection skills, and a unique ability to find the barrel. He's a line drive machine. Better still, he's an above average runner whose 6-foot-3-inch frame continues to show athletic growth.
Di Maggio has a unique swing. He sets up with a wide base, slightly open to the pitcher with some frenetic tempo in his waggle. He has a short, quick stride with a moderate leg lift and understated move foward. He will at times exaggerate his leg kick and stride to try and tap into more power in ambush counts. Di Maggio's balance and ability to repeat in the box stand out. He lets his hands handle his timing windows, rather than working to coordinate with his lower half. His ability to lag the barrel and create stretch in his upper-half is where Di Maggio generates his power. It's safe to assume above average raw power in the tank, perhaps more as he adds strength. Di Maggio is not the most elastic hitter, instead relying on tension to let the strength in his hands/shoulders play. Given what he's shown thus far, it's fair to project a potential plus hitter with above-average or better power in games at full maturation.
As noted, Di Maggio is an above average runner who gets strong reads in the field. He's got arm strength that plays in all three spots. His throws present carry and accuracy on the bag. If Di Maggio gets to above average or plus speed and can hold it, he's got a chance to play center, otherwise he'll comfortably slide into right field.
Di Maggio has a lot of similarities to 2026 SoCal draft pick Jared Grindlinger. Incredible polish, age, size and length, and tools that play from the left side. He's one of the top talents in the 2028 class, and a model darling.
