Wall is a unique prospect, possessing the speed of a center-diamond player but lacking the defensive value or arm strength to follow suit. He was the rare high school second baseman that went early in the draft, going to the Rockies in 2014’s CBA round out of Orangewood Christian (FL). Several years into his development, Colorado has moved him to the outfield in hopes his plus speed translates there. In July of 2018, Wall was one of the prospects Colorado traded to the Blue Jays for RHP Seunghwan Oh.
Following shoulder surgery in high school that left him without much arm strength, his throwing is stretched considerably in center field. The transition to the outfield is a work in progress, and his routes and reads off the bat don’t look like they will play at the position. Wall will likely always have the ability to fill in at second base or center in a pinch, but the only place he looks capable of playing regularly at the big league level is left field. That, of course, requires the bat to play big, and as a hit-over-power offensive profile, it’s unlikely the future role is that of an everyday player on a corner. There is chance for an above-average hit tool however, as Wall shows the ability to work counts and spray line drives to all parts of the field. A 70-grade runner (4.0-to-4.05 seconds up the line), he’s able to stretch hits for extra bases and beat out ground balls to the infield. I believe that he’s a future big leaguer–the approach, contact, and speed have Major League utility, I just don’t see it in a regular role. He’s likely to provide value off the bench, able to put the ball in play and provide late-game speed.
