The ATP Tour Final event at the O2 Arena last weekend marked the end of the men's tennis season. We're taking a trip down memory lane to see how much of the year you can remember.
And what a year it was, Nadal was finding his form again after injury, Murray was growing in confidence from the Olympics and Djokovic was sliding and stretching all over the court as only he can.
The season started as ever down under with the Australian Open. The event has been dominated in recent years by Djokovic, can you recall how he got on this season?
Nadal pulled out of the Australian Open 2 weeks before citing a stomach virus, having missed much of 2012 with tendinitis in his knee a few tongues were still wagging. Yet as 2013 passed, Nadal was only getting stronger and managed to end the season, as I'm sure you know, with ? Grand Slam titles and seeded #? - you may need that information for the quiz!
This year it was Murray who ended the season under the knife, missing out the ATP Tour Finals in order to have back surgery. He's already flown back to Miami to start his rehab and training and he'll be chomping at the bit to start the 2014 season at the Australian Open.
Roger Federer will also be keen to get back on court having finished 2013 seeded 7th, it was the first time he's not reached a slam final since 2002.
Many of the top seeds had indifferent years at the Slams, losing in the first rounds, or in the case of the Wimbledon Championships this year, many retired with injuries.
So for some it was a year to forget, for others, something happened that they've been waiting 77 years for and it will be talked about for long over another 77 years.
Test your knowledge of the 2013 Men's Tennis tour with our fun quiz above. Good luck.
