Rafael Nadal cramps up in the middle of victory speech (Video)

It's been a tough year for Rafael Nadal. It seems that even when he's winning, there is something going wrong.

During his victory speech at the the Hamburg Open, the former world number one began to feel a cramp in his leg. Whereas most of us would roll around the floor in pain, Nadal simply laughed and tried to carry on, saying: "It's not a joke," before adding, "I don't know what to do." https://twitter.com/sluggahjells/status/627846231096754177 https://twitter.com/sluggahjells/status/627847433054199808 H/T SB Nation
