Deep load, electric wrists, generates torque at trigger, can get flat at launch w/ mild wrap; length into the zone, plus bat speed, shows quality hand-eye; long stride w/ aggressive weight transfer, some balance issues, gets to front side too early on the regular; will stay open, early struggles with inside velo have improved, strength and bat speed to inside-out with authority; extreme aggressiveness has shown signs of toning down, still expands zone up and out against velocity and struggles to track breaking balls, will get caught guessing; above-average hit projection based on plate coverage, wrist strength, and solid bat-to-ball, with demonstrated improvements in the approach
50 present raw, projection for another half grade; plus bat speed with mild leverage, present approach significantly limits game utility, works to center and opposite field with line drives; has improved ability to turn on pitches, strength to drive the ball with mild carry; 15-homer power potenial with average or better extra base-hit production
4.24 average on nine clocks, not consistently clean out of the box; fluid running motion, second gear can push plus; raw baserunner, over-aggressive, will lose his coaches, incremental improvement; struggles to time pitchers and release on stolen-base attempts, flashes average future base-stealing skills
Raw defender, incremental improvements, more corner starts as season has progressed; can struggle with early reads and route inefficiencies, will rush and get ahead of plays; easy actions, closing speed to track into gaps and behind, outstanding body control; chance to stick primarily in center, versatility to move around

Signed out of Cuba for a hefty bonus last fall, Diaz has held his own as one of the youngest regulars in the California League all season. He's a raw player, and while there is in some cases a sizable gap between his present and future grades, his skill set doesn't really have any holes. The approach and swing mechanics are both inconsistent, but he has the skill set to develop into a quality hitter, and he has the frame to grow into more power. He's not a great base-runner at present, but there's above-average or better straight-line speed that plays well in the outfield. There's enough track-and-close skill to leave him primarily in center for now, and he possesses enough arm strength to handle either corner if he doesn't quite get there up the middle.
This is a potential above-average regular if it comes together, one who does a little bit of a lot of different things to help a team win, and does everything pretty well. The skill set is broad enough to where he's a lower-variance prospect despite a longer probable lag time to the majors.
