|Committed to Miami and a preseason All-American this year, Martinez has competed for Team USA's Junior and Youth national teams and was an Aflac All-American. This spring, he has struggled to translate his talent into production. At 6-foot-3, 190 pounds, he has a projectable pro body that is still growing. He is likely to outgrow shortstop but should become an above-average defender at third base. An average runner, he is athletic and moves well, with good actions in the field and a solid arm. In batting practice, Martinez shows above-average raw power and good hitting mechanics, but in games, his struggles begin. He has major timing issues and often reverts to a swing with no load. While he has fallen from a first-round prospect, a team will still take a chance on Martinez, and repeated at-bats in the minor leagues may be just what he needs.
