Scouting Report: Robles had impressed Nationals evaluators for years before breaking out in 2015 during his U.S. debut. He signed with Washington for $225,000 in 2013 and impressed in the Dominican Summer League the following year. He wowed the Nationals during extended spring training in 2015, then carried that performance over to the regular season in the Rookie-level Gulf Coast League and short-season Auburn. He ranked as the No. 2 prospect in both leagues while hitting a combined .352/.445/.507 with 24 stolen bases in 61 games. Robles advanced to full-season ball in 2016 for the first time, beginning the season at low Class A Hagerstown. After earning a spot in the South Atlantic League all-star game, he was promoted to high Class A Potomac, where the 19-year-old was the youngest player in the Carolina League. He again ranked as a top prospect in two leagues-No. 1 in the South Atlantic and No. 3 in the Carolina. Robles was sidelined for about three weeks in the second half of the season by a thumb injury he suffered after being hit in the hand by a fastball, one of 34 times he was hit by a pitch in 2016. Even as he has raced through the minor leagues, Robles has continued to hit and earn praise for his baseball IQ and willingness to learn. Robles has excellent quick-twitch athleticism and true five-tool potential. He is advanced for his age, displaying a good feel for hitting. He has strong, quick hands that help him to produce impressive bat speed. Presently, his power results mostly in hard line drives to the gaps, but as he physically matures, those balls should start going over the fence. He sometimes gets big in his swing as he tries to drive the ball with more authority. He has a good feel for the barrel and is difficult to strike out, though he does not often walk. He sets up very close to the plate, which allows him to cover the outer half of the plate well, but also results in him often being hit by pitches. He is confident in his ability to turn on inside pitches, but after his stint on the disabled list he is also starting to learn about the importance of getting out of the way of inside pitches. Robles is a plus runner and makes good use of his speed on both the basepaths and in the outfield. He tracks down balls well in center field and has plus arm strength. His defensive ability and speed enable him to impact the game in many different ways. He plays with lots of energy in all facets of the game, a trait that endears him to teammates, coaches and scouts alike. Robles has proven to be capable of moving quickly in the minors and will likely return to Potomac to open 2017. Because he won't turn 20 until May, he will likely again be among the youngest players in the Carolina League. It will be a challenging assignment for the precocious outfielder, but his makeup and dynamic skill set should help him continue to find success against older competition. He has all-star potential and could arrive in Washington late in the 2018 season and be a regular player at age 22 in 2019.
