"justin upton with a terrible approach"

OF Adam Brett Walker (Twins): Tools for days, but still learning how to use them and whether he gets there is a question; long limbs, high butt. Stands tall in the box with a quiet stance. Can get long but not terribly so for a player with long arms. Easy plus bat speed and plus power potential; doesn’t have to sell out to generate power. Generates natural backspin on ball. Over-aggressive at the plate because he can get the barrel on too many pitches, resulting in bad contact. Is willing to use the whole field but expands the zone to hit pitcher's pitches; got one pitch up in the zone and crushed it; no doubter with easy carry. He reminded me of Justin Upton with a terrible approach. –Jeff Moore

SS Jorge Polanco (Twins): Busy early in his stance as pitch is being delivered but still maintains quickness to the ball thanks to natural bat speed and quick hands/reaction time. Showed line-drive/gap power and should run into a few home runs on pitches in his zone, but power is mostly for doubles. Looked to go back up the middle and hit what pitcher gave him. Looked to bunt for a hit. Has naturally smooth hands in the infield with a quick first step. His lateral range is average at best for shortstop but would play at second base. Quick release and plenty of arm for 2B but is maxed out at SS. –Jeff Moore
