High school wrestling can be a challenging sport to photograph. There are a lot of little burst of peak action as well as arms, legs and a referee to get in the way of clean images. Along with soccer, wrestling is great for capturing expressive moments, which are unobstructed by a helmet and face mask. The image below only happened for a split second and being able to see the athletes faces helps portray a sense of emotion after their match.
