Fernando Tatis Jr.: Shortstop, Tampa Bay Rays
n his first 84 games at the major league level, Tatis Jr. slashed .317/.379/.590 with 22 home runs, 53 RBIs, 16 stolen bases and a 3.6 fWAR. Never mind if that type of production when put up over the course of a full season would have been enough for him to challenge Pete Alonso for the National League Rookie of the Year, had Tatis Jr. kept that production up over a 162-game span, he would have drawn National League MVP consideration in his first season. Unfortunately for Tatis Jr. and the Padres, the shortstop was limited to just 84 games despite breaking Spring Training with the major league camp. A hamstring injury cost him the entire month of May. A back injury ultimately ended his season in mid-August. Certainly, Tatis Jr.'s health is something to monitor in 2020 and moving forward, because it seems to be the only thing that could stand in the way of him being one of the most productive players this decade.
