Video: Tennis player nearly KO’s doubles partner with wayward serve

This is why you need to have a lot of trust in your doubles partner while they're serving.

Fans inside the O2 Arena in London were treated to some inadvertent physical comedy during the ATP tour doubles final yesterday. Doubles legends the Bryan brothers had serve when the incident happened. Bob Bryan mishit his service which rather forcefully connected with the back of his twin brother's head while he was at the net, causing him to fall to ground in a heap. Luckily, Mike took the shot like a pro and swiftly got back to his feet. Most of the bruising he endured was to his ego. Despite the mishap, the American duo took home the ATP tour finals trophy  with an emphatic come-from behind victory (6-7 (5-7) 6-2 10-7) over Croatia's Ivan Dodig and the Brazilian Marcelo Melo. https://www.youtube.com/watch?v=0gaEta_SDCM
