So long as the Braves don't choose to keep him in the minors for significant time trying to buy additional time before his arbitration and eventual free agency a few years down the road, that is. In 2017, he was one of six players in professional baseball with at least a .300 batting average, 20 home runs and 20 stolen bases, showing his natural ability to fill every primary Rotisserie category. While Acuna might require some time to fully adapt to the big leagues as he's still only 20 years old, the fact he possessed good plate-discipline metrics in the minors -- 8.8 percent walk and 76.4 percent contact rates -- makes him more likely to do so quickly than a typical rookie might. In dynasty leagues, he makes a compelling case to be a building-block, early-round selection. In redraft formats, he's more of a mid-round pick, but that bar could raise or lower depending upon how his spring plays out."},"fullName":"Ronald Acuna Jr.","playerRater30DAY":9,"playerRater15DAY":5.6,"playerId":7448}
