Juan Soto only made 512 total Minor League plate appearances before the Washington Nationals called him up on May 20th, 2018 to make his MLB debut. On Opening Day this year, he was playing for the Hagerstown Suns in Single-A. But since joining the Nationals, he’s been one of their best hitters.
Not since the days of 19-year-old Bryce Harper has a Nationals rookie been successful so quickly. And while Harper arrived in 2012 as a once-in-a-generation talent, Soto is a more mature, more disciplined hitter than Bryce was at the same age.
