Wimbledon’s No. 1 seed Novak Djokovic isn’t known for keeping his emotions in check. The 26-year-old Serbian is this year’s favorite to win the tournament, which he took back in 2011, but you wouldn’t know that from his emotions. When he plays, Djokovic’s personality and emotions are out on the court for all to see, and with his mouth open that wide, he better hope there are no insects around. This celebratory display followed his fourth-round victory over Tommy Haas, and if Djokovic makes it as far as he is expected to in the tournament, the quantity of these images is due to increase exponentially.
