Justin Corona best tool is his speed, and it's plus-plus. It allows him to be a game-changer on both sides of the ball, as a major extra base threat and an outstanding defensive shortstop. He makes consistent contact and has more extra-base pop than one might think based on his frame. He's improved his on-base skills, clearly demonstrating an understanding of what it will take to be a prototypical leadoff hitter in at the Lake County level in the future.
