Here is the famous Batting Stance Guy imitating each player from the 2009 Yankees lineup. In order, he emulates Brett Gardner, Derek Jeter, Mark Teixeira, Alex Rodriguez, Robinson Cano, Johnny Damon, Xavier Nady, Nick Swisher, Hideki Matsui, Jorge Posada, Jose Molina, Melky Cabrera, Ramiro Pena, Aaron Boone and Bucky Dent.
In general, he seems to over exaggerate the small quirks he notices from hitter to hitter. However, I think he does a great job with Gardner, Jeter, Matsui and Posada.
Also, it is clear that the people filming are not Yankees fans, as they were disappointed when he did Boone and Dent.
