Brian Dozier was on MLB Network yesterday and the Twins' second baseman -- in the midst of a 25-game hitting streak, by the way -- and demonstrating the changes he made in order to go from a puncher of a middle infielder to a a second base capable of bopping 40 home runs.

If you are a player, coach, instructor or just a fan curious to know the thought process behind Dozier's development, you have to watch this.

The overall segment could have gone smoother (or shorter) if Mark DeRosa did not keep interrupting or interjecting his thoughts and allow Dozier to talk. When Dozier did get to explain his methods, he shared one of the most critical parts about the swing: Hands are the enemy of the swing.

"Hands just hold the bat," Dozier tells DeRosa, which is something that the Orioles' Chris Davis told him. It's not the hands or arms that generate the power, it's the firing of his hips that drives the ball.
