Video: Federer teams up with Sharapova, Nadal with Azarenka

Roger Federer teamed up with Maria Sharapova to take on Rafael Nadal and Victoria Azarenka at the Nike Clash of Champions in Oregon in 2011. John McEnroe was present too as he took over the chair umpiring duties. The game also included former Oregon quarterbacks Joey Harrington and Dennis Dixon as “celebrity line judges”.

There’s never a dull moment with Johnny Mac around as one of his quips demonstrated when he told Federer – “Now that you have two kids, you can try that without worrying,” after he hit a between-the-legs shot. The players were all there to raise funds for their respective charity foundations. As one of the captions said, it was indeed “Legendary Tennis. Serious Fun”
