The Cardinals were very high on Montero internally, though he wasn’t a particularly known commodity until exploding onto the national prospect scene in his full-season debut last year. Montero was named Midwest League MVP despite not even finishing the season there, slashing .322/.381/.529 with 15 home runs and nearly 30 doubles before moving up to High-A.
Though his youth still shows through offensively—occasionally over-eager and apt to expand the zone—his high offensive ceiling puts him near the top of this list. Montero has the tools of an above-average hit and power producer, with room to grow into more raw as he fills out a physical 6-foot-3 frame. Defensively, he’s currently at 3B and has at least some chance to stay there as his body matures. It’s possible he tries a corner outfield spot or moves to 1B, though a strong arm will help his case to remain at the hot corner for now.
