According to ZiPS, Daniel Poncedeleon need only throw 119.1 innings and he would be a 1.3 WAR pitcher. In other words, ZiPS thinks Poncedeleon is roughly an average pitcher if he were to pitch a full season (1.9 WAR over 175 innings). This was easily the most surprising projection from ZiPS to me.
Poncedeleon, if he were to accomplish anything close to that in his major league career, very much fits the mold of the classic old Cardinals prospects. He was drafted when he was 22, a college senior. He dominated State College, but that is to be expected of a 22-year-old pitcher facing much younger competition.
