Juan Soto becomes the first player in MLB history to record 100+ extra-base hits and 50+ doubles in his age-20 season or younger. Soto, who turns 21 on October 25, reached the milestone in the Nationals' 4-3 win over the Reds on September 24. The 2018 first-round pick is just the 10th player all-time to reach 100 extra-base hits before turning 21, joining a list that includes Hall of Famers Mel Ott and Mickey Mantle.
