Not only is Acuna the best prospect in baseball, he might be the best prospect to come along since Mike Trout and Bryce Harper were competing for pole position in 2012. It's incredibly rare for a 19-year-old prospect to earn a promotion to Triple-A, but Acuna, who opened the year at High-A, didn't just stop by to get a lay of the land. He was immediately the best player in the International League and was 62 percent better than the league's average hitter (162 wRC+) over 54 games. Dripping with fantasy-relevant tools, Acuna has the speed to steal 30-plus bases, enough power to hit 30-plus homers and the approach and bat-to-ball skills to hit .300. While he didn't show the same patience last year that he did in his first two professional seasons, he will be an OBP monster when appropriate fear is established in the minds of big-league pitchers. Acuna will be promoted to the majors in mid April, once the Braves have secured an extra year of control, and he could be a five-category force from Day 1.

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.
