This is what Jeff Moore of Baseball Prospectus said of Arreas on August 24: In the low levels of the minors, there are a ton of slick-fielding, athletic middle infielders with little to no power. It's not that that's a bad profile, but in order to stand out, a player in this mold has to have something extra. Arraez is doing that thus far, as his something extra is bat control within the strike zone. This is aided by an incredibly short swing path that makes no attempt to drive the ball or hit for any power, but there are plenty of players with similar swings who still swing and miss plenty. Arraez, despite being just 18 and stateside for the first time, makes contact at incredibly consistent rates, and even though he doesn't drive the ball, he does connect solidly. His approach is primarily to hit up the middle and the other way, which limits his power even further. Arraez is limited to second base and needs to hit .300 to succeed, and average foot speed limits his overall profile further, but his contact skills and barrel control are also rare for an 18-year-old, which gives him a chance to max out that profile. – Jeff Moore
