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. Read Past Outlooks
