Antuna, now 20 years old, left the Dominican Republic in 2016 to sign with the Nationals for a hefty bonus of $3.9MM. He has since split his time between rookie and Single-A ball. Although he missed all but three games last year because of Tommy John surgery and lower body injuries, Antuna’s still regarded as one of the Nationals’ most promising prospects. Baseball America (No. 9), FanGraphs (12) and MLB.com (12) each place him near the top of Washington’s system.
