Cartaya posted a composite .254/.389/.503 slash line with 22 homers, 72 RBI and 74 runs across 95 games split between Single-A and High-A this season.
While those overall numbers definitely got a boost from his time in the hitter-friendly California League, Cartaya's .856 OPS in High-A at age 20 is still impressive. He's striking out too often -- 119 times in 445 plate appearances, a 26.7 percent clip -- but Cartaya also draws plenty of walks and offers rare power at the catcher position. Among prospect backstops, perhaps only Francisco Alvarez offers more upside.
