Baseball America for one. They love his power, but they have also bragged on his swing mechanics, pitch recognition, patience, consistency, and ability to drive the ball to all fields.
His weight and power tend to draw all the headlines (good and bad), but there is more to Vogelbach than 500 foot home runs. I had hoped he'd be in Peoria already, but we should get to see him in action before too much longer. We'll have a better idea where he is then.
BA is the only scout/scouting service who publishes stuff for the public who believes that then.
