Here's a look at 2008 first round draft pick Yonder Alonso crushing one for the Hawaii Winter Baseball League Beachboys. It's nice to see him pulling the ball with authority, after being more of an opposite field power hitter at the University of Miami.
Enjoy and thanks to gianthawaiian78 for posting it:
And, here's another, albeit, more uneventful at bat by Yonder. Still, you can see his swing mechanics (i.e. high hand position and open stance to start, stepping towards home plate in the stride to close up the stance and body) and see a bit of his disciplined approach at the plate.
