Scouting grades: Fastball: 60 | Changeup: 55 | Control: 50 | Overall: 40

Rosario was a Top 100 prospect after he reclassified to graduate from high school in 2020, but the combination of the shortened Draft as a result of the pandemic, questions about his profile and his commitment to Miami meant the right-hander went undrafted. He’s been a part of the Hurricanes' rotation since and has been fairly enigmatic throughout, including this season, with very good stuff but without the results to match.

Pure stuff-wise, Rosario is up there with some upper-echelon college arms. He’s touched triple digits with his fastball and averaged better than 95 mph with the pitch this spring. But there’s little deception and it’s pretty true, leading it to get hit more than it should, though he’s had some success in sinking it at times. His low-80s slider has improved and misses a fair amount of bats, and he’s been more committed to throwing his upper-80s changeup that can be a swing-and-miss pitch and get ground ball outs.

Rosario’s command in and out of the zone is spotty at best, and his walk rate went up in 2023, as he tends to let things snowball, leading to big innings. He had a brief but very successful stint in the Cape Cod League last summer and teams that think they can help him unlock that kind of performance more consistently will be interested in taking his pure stuff at some point on Day 2.

Scouting grades: Fastball: 60 | Slider: 55 | Splitter: 60 | Control: 50 | Overall: 55

Rosario reclassified into the 2020 Draft as a Florida high prepster and rated as a top-three-rounds talent, but he went undrafted because of his commitment to Miami. Though he logged a 6.53 ERA in three seasons with the Hurricanes, the Rangers saw enough potential to draft him in the fifth round in 2023. After making some changes to his delivery and the manner in which he deploys his pitches, he posted a 69/5 K/BB ratio in 47 innings in Single-A this spring before earning a promotion in June.

Rosario is finding more success with his fastball, which sits at 94-98 mph and touches 100, by focusing on running and sinking it down in the strike zone. He's also capable of blowing it by hitters at the letters. He misses bats with both of his secondary offerings, an 88-92 mph splitter with nice tumble and a tight 83-85 mph slider.

The Rangers worked with Rosario to keep his delivery closed longer and hide the ball better from hitters. He already provided some deception with his low release height and flat approach angle, and now he's pounding the strike zone better than ever. It’s early in his pro career but he's living up to the promise he showed in high school and could develop into a mid-rotation starter.

Rosario was originally slated to be in the 2021 Draft class, but would have been 19 at the time, so the Miami-area prepster reclassified to be a part of this year’s Draft. He certainly got added to follow lists everywhere after showing off impressive arm strength at a number of summer showcase events, from the East Coast Pro Showcase to both the Under Armour All-America Game and the Perfect Game All-American Classic.

While he is a bit undersized, Rosario is strong and athletic. He also has an extremely fast arm that was firing fastballs up to 97 mph all summer long, and touching 99 mph early this spring. He complements the heater with a splitter that takes on different shapes and forms, sometimes looking like a power pitch and sometimes looking like a bigger, looping breaking ball without the spin. It's very effective as an offspeed pitch and he is working on adding a cutter-like option to his arsenal.

Scouts love how Rosario goes right after hitters, but there are concerns about whether he will have the repertoire and the command to be a starting pitcher. His delivery is OK, though he loses his release point at times, and he's more thrower than pitcher now. Pitchers who profile as relievers in high school are always harder to place on Draft boards, but the Miami recruit’s pure arm strength is sure to intrigue many teams.
