When Gerald Green gets in the open court, the result is always the same - a jaw-dropping dunk. 

In the fourth quarter of the Miami Heat's preseason game against the Charlotte Hornets, Green stole the ball from rookie Frank Kaminsky and then raced down the court to deliver an impressive windmill slam.

This may be the first game of the preseason for the Heat but Green's dunking is already in midseason form. 

Gerald Green is very good at dunking.
