"This photo was taken over the old grandstand. Players serve the ball in many different ways and I am always studying their movements and facial expressions when I think of photographing them. I noticed Sara #Errani would open her mouth wide open every time she served. I thought with the right light and if I could time the picture right it would work out to be a very dramatic picture. It took two days of shooting this but in the end I finally got it." - albello55 | September 5, 2015 | #GettySport _ Getty Images sports photographer Al Bello is taking over gettyimages for a look at his favorite #USOpen moments.
