In addition to dubbing him the seventh best prospect, Mayo also named Alonso the highest rising player at the position saying:
Alonso entered his first full season of pro ball nowhere near the Top 10 first basemen list, even though he had hit very well during his summer debut following his second-round selection by the Mets out of the University of Florida. But then he showed that wasn’t an aberration and hit his way to Double-A, with very solid hit and power tools showing up.
Last season, Alonso played for both St. Lucie and Binghamton. Even with him suffering a broken hand early in the season, Alonso still hit .289/.359/.524 with 27 doubles, a triple, 18 homers, and 63 RBI in 93 games.
It should come as no surprise that MMN recently ranked Alonso as the top first base prospect in the Mets organization. Stay tuned to see where MMN ultimately ranks Alonso among all Mets prospects.
