An under-the-radar July 2 international signee out of Venezuela in 2014, Acuna has hit at every stop in pro ball, showcasing high-end tools along the way. He missed 15 weeks in the middle of the season with a thumb injury, but his .819 OPS would have ranked sixth in the Sally League, just behind top Rockies prospect Brendan Rodgers, if he had enough plate appearances to qualify. At 18, he would have been easily the youngest player in the top-10 on that leaderboard, and his 14 steals in just 40 games serve as another separator. The case can be made that on a per-game basis, Acuna was the most impressive hitter in Low-A last year, when factoring in age. He projects to grow into plus power and should maintain above average speed through his prime years, but we won't know what kind of hitter Acuna will be until he gets a taste of quality offspeed stuff at Double-A and Triple-A.
