Scouting Report

Scouting grades: Fastball: 70 | Slider: 55 | Changeup: 45 | Control: 40 | Overall: 45

Perales signed for $75,000 out of Venezuela in July 2019 and quickly opened eyes when he ran his fastball up to 95 mph in the Dominican Republic's Tricky League a month later. He got off to a slow start as a pro with the pandemic delaying his debut until 2021, when he made just one appearance before getting shut down with a minor injury. He overpowered hitters at the lower levels and reached Double-A at age 21 this June, but he blew out his elbow in his second start and required Tommy John surgery.

Though he lacks physicality, Perales has electric arm speed that produces mid-90s fastballs that reach 99 with a flat approach angle and tremendous carry. It's a plus-plus weapon that would be even more effective if he had more reliable pitches to back it up. His mid-80s slider has two-plane depth at its best but lacks consistency, and he hasn't shown much feel for a too-firm changeup in the upper 80s with a bit of life.

Perales is athletic and moves well down the mound, creating extension that adds deception, but he's also small and throws with some effort. He never provided regular strikes before his brief 2024 season, and his inability to land his secondary pitches at times can lead to his fastball getting hit harder than it should. He has the upside of a mid-rotation starter if he can regain his health and polish his offerings but could wind up as more of a late-inning reliever.

Scouting grades: Fastball: 70 | Slider: 60 | Changeup: 50 | Control: 45 | Overall: 45 

Perales was relatively anonymous when he signed for $75,000 out of Venezuela in July 2019, but that quickly began to change when his fastball hit 95 mph a month later in the Dominican Republic's Tricky League. The pandemic delayed his official pro debut until 2021, when he made just one appearance in the Rookie-level Dominican Summer League before Boston shut him down with a minor injury. He dazzled in the Rookie-level Florida Complex League last summer and made a four-start cameo in Single-A at age 19. 

Perales has a lightning-quick arm that produces fastballs that park in the mid-90s and tops out at 99 mph with riding action up in the zone. His mid-80s slider features two-plane depth at its best and shows the potential to become a plus pitch, and he also can turn it into a harder cutter. He's in the early stages of developing a changeup that has upper-80s velocity and some fade. 

Similar in build and arsenal to fellow Red Sox Venezuelan pitching prospect Wilkelman Gonzalez, Perales has more power but less polish with his secondary pitches. He generates his stuff with less effort than Gonzalez, though he needs to prove he can handle a starter's workload and deliver enough strikes. He has the upside of a No. 3 starter if he remains in the rotation and perhaps closer ceiling if he winds up in the bullpen.

Scouting grades: Fastball: 70 | Curveball: 55 | Changeup: 45 | Control: 50 | Overall: 40 

The Red Sox signed the unheralded Perales for $75,000 out of Venezuela in July 2019 and other teams took notice when he started pushing his fastball to 95 mph a month later during Tricky League action in the Dominican Republic. The pandemic delayed his official pro debut until 2021, when he made just one two-inning appearance in the Rookie-level Dominican Summer League before getting shut down with a minor arm injury. Boston continues to handle him with care, but he has been fully healthy and dazzling in the Rookie-level Florida Complex League this summer. 

Though he's not very physical, Perales has a quick arm that produces fastballs that sit in the mid-90s and reach 99 mph with good carry. He also shows feel for spinning an upper-70s curveball that could become a plus pitch once it adds more power and consistency. His meager pro experience has limited his opportunity to work on his rudimentary changeup. 

While Perales lacks size and projection, he has added strength since signing and generates his impressive stuff with relatively little effort. He shows aptitude for repeating his delivery and throwing strikes, though like most youngsters he'll need time to refine his command. He's a high-variance pitching prospect who should be ready to make his full-season debut in 2023.
