It is no secret that the Phillies have a surplus of young starting pitching. Last I checked the Phillies had 16 starting pitchers on their 40 man roster with already graduated prospects such as Jake Thompson, Zach Eflin, and Alec Asher on the outside looking in. This has left the upper minors a bit bare of higher upside pitching prospects. In place of polished starters, the system is producing high upside Latin American arms at an exciting rate. This year’s list is topped by three Dominican righties who represent the GCL Phillies’ big breakout prospect for the past 3 years running.
