Fisher has more power but very similar skillsets. Tommy Pham comes to mind as the type of ceiling a non-concussion Pompey and Fisher have.
Fun fact - Pompey was Baseball America #30 in 2014
The 17-year-old Pompey was one of the youngest players in the 2010 draft and signed for $150,000. He had something of a storybook season in 2014, playing at four different levels and reaching the major leagues. A plus athlete, Pompey is a premium defender. His gap-closing defense has drawn plus-plus grades from scouts. He offers an above-average arm that could play in right field. His speed is at least plus and is capable of the occasional plusplus time out of the box. He is a smart, efficient basestealer who can impact games on the bases. The switch-hitter could become an above-average hitter who draws walks at an above-average clip throughout his career while producing above-average contact rates. His quick-twitch athleticism translates to the batter's box with natural whip and bat speed. He will likely hit 10-15 home runs annually with lots of extra-base hits. Pompey's defensive and baserunning prowess gives him a high floor and the development of his bat could give him a well-rounded skill set capable of contributing in nearly every phase of the game.
