Video: Serena Williams marks epic comeback with truly amazing shot

We've got a lot of time for Serena, and we've got A LOT of time for this!

2015 has been an amazing year for tennis superstar Serena Williams, and her antics at the US Open last night made her year even better! 

The American started 2015 by winning the Australian Open, brushing aside rival Maria Sharapova in straight sets. She then went to the French Open and despite a wobble in the second set, she managed to beat Czech star Lucie Safarova – then followed her sixth Wimbledon crown to set her up for her infamous 'Serena Slam'.

And she moved a step closer to hitting that target after beating her fellow countrywoman Bethanie Mattek-Sands on Friday - winning 3-6, 7-5, 6-0 in a thrilling encounter.

Sure she won, but only after pulling off an epic comeback against  Mattek-Sands. It was what she did in the third set that was absolutely amazing and proves why Serena is still the queen of tennis! 

Just watch this... 

Yep, that's right, Serena managed to win the point while doing the splits and celebrating at the same time! This is surely enough for her to go on and win the Grand Slam now, as she should be able to get past her next opponent, Agnieszka Radwanska. 

Well played Serena, well played!
