Track Record: Madero trained with former D-backs scout Miguel Nava as an amateur in Venezuela and signed with Arizona when he was 16. He never got out of short-season ball in four seasons with the D-backs, and they traded him to the Angels for David Hernandez in 2017. In his first full season in the Angels system, Madero jumped from low Class A to high Class A.
Scouting Report: Madero worked hard in the weight room to add muscle before last season and the results could be seen in his fastball, which reached 94-95 mph toward the end of 2018 after topping out at 91 mph in 2017. He can throw his breaking ball, which is a more side-to-side slurve than curveball, and his swing-and-miss changeup, which has nice fading action, in any count. He has a smooth, repeatable delivery and takes a big stride off the mound, creating good extension. Madero is polished for his age and has good command. The Angels love his work ethic and are encouraged by the strides he made last year.
The Future: Madero's increased velocity now makes him a viable starting pitching prospect. He may see Double-A in 2019.
