Scouting Report: A fringe-average hitter, Johnson was starting to come into his own offensively before his injury, and scouts believe he has at least above-average raw power thanks to his quick hands and natural strength. While he lost a month of valuable at-bats, the Nationals were excited about the progress that he made in 2018 defensively, improving his jumps, route-running and throwing accuracy. Johnson has 70-grade arm strength and is starting to take advantage of it with better decision making. His plus speed allows him to play every outfield position, though his arm strength makes right field the best fit--and that's where he played the majority of his innings in 2018.
The Future: A full season of health in the upper minors will give a more clear picture of what sort of offensive player Johnson really is, and with his defensive strides he could wind up debuting at some point late in 2019.
