From Baseball America:
Perkins:
Perkins, an Arizona State commit, brings a certain grace and smoothness to the field. The best athlete among all Arizona high school position players, he's got five tools with average-or-better potential. Perkins is a natural center fielder and seemingly glides to balls in the outfield. He sees the ball off the bat well, takes good routes and catches the ball easily. He's at least a plus runner with a smooth stride in motion and shows off a good arm in the outfield. At the plate, Perkins' hands work well and he's got good bat speed, with the ball jumping off his bat, but he needs to get stronger and tighten up the swing somewhat in order to become an impact hitter. He hits line drives to all fields and projects to have average power once he physically matures.
Stevenson:
At times this season, Louisiana State would field a trio of outfielders who could play center field in pro ball, but there was little question who would be standing in center field for the Tigers. Stevenson is one of the best center fielders in college baseball and projects as an above-average center fielder in pro ball thanks to 70 speed, excellent routes and a knack for making the diving catch. His below-average arm is his only weakness defensively. At the plate, Stevenson lacks the picture-perfect swing lefthanded hitters often possess. He’s cleaned it up and made it less mechanical in the past year, but it still is an arms and upper-body swing that looks to slap the ball up the middle or the other way, resulting in bottom-of-the-scale power. His speed makes that work, and he's ranked among SEC leaders in batting average each of the past two seasons. He profiles as a top-of-the-order center fielder whose defense may allow him to play even if his bat forces him to the bottom of the lineup.
