Martinez struggled to settle in to his full-season assignment, but after a few rough viewings in April and May it became evident that he was beginning to make needed adjustments. He shows all five tools, with premium bat speed, plus raw power, present speed, and arm strength, and no below-average grades in the books. There's a natural feel for hitting, and he has demonstrated an ability to sit on pitches, though the approach is still exploitable at present. There is above-average regular potential on the strength of the natural talent, but there is a higher risk he doesn't continue to adapt and max out.
