Men's player of the year
There are two men who stand out for me following their performances in 2011, and they are Novak Djokovic and Roger Federer.
I certainly did not see Djokovic's success coming, and he completely revolutionised his game and set the world alight as a result of his incredible improvement.
Federer has enjoyed a truly brilliant end to the year, and that is really heartening.
It was quite a renaissance for the Swiss, and it bodes well for him having a distinguished 2012 with perhaps one or two more Grand Slam wins.
Djokovic has to be the player of the year if I am picking just one, for all that he achieved and the unbelievable transformation in his game.
Women's player of the year
Petra Kvitova wins this award hands down. The Czech has really thrived this year, and she went from being outside the top 30 at the start of the year to now being number two in the world in what was a stunning assault on the women's game.
To win Wimbledon was a magnificent achievement, but it was the way in which she won the WTA Championships which really demonstrated her strength of character.
Kvitova held her composure and nerve superbly at Wimbledon, before encountering quite a pronounced slump following the success and she had to respond to that disappointment towards the end of the year.
She has now shown that there is more to her game than a powerful, gung-ho approach and only Serena Williams on her day can live with the Czech looking ahead to next season. 2012 will be a very big year for her and she is looking very ominous.
Match of the year
This is a very hard one, but it has to be the US Open final between Rafael Nadal and Djokovic. For all of four hours and 10 minutes it was enthralling tennis and a delight to watch.
Nadal threw absolutely everything at the Serb, but it was still not enough. Djokovic proved that he has a different gear in the big matches, and he rose to the occasion quite spectacularly to edge out his great rival.
Djokovic was simply sensational, and the match was played at a frightening pace with some unbelievable retrieving and groundstrokes.
It was a masterclass of tennis at the top level, and that has to go down as the match of the year.
Best match to commentate on
It was a match at Wimbledon which really stuck with me, between Grigor Dimitrov and Jo-Wilfried Tsonga. It was a fantastic encounter, and one of immense quality and excitement.
The two players embraced each other for several seconds at the end of the match, and it was most definitely the highest quality clash in the tournament. The crowd rose to their feet with a standing ovation, and that was quite fitting.
Dimitrov has so much potential and, while he may fail to truly live up to what is expected of him, on this occasion he was truly brilliant.
The shots he produced against Tsonga in that match were thrilling to watch and Tsonga was taken aback by how inspired his opponent's play was. It was a quite staggering performance.
I can recall the most incredible rallies: brutal hitting, remarkable saves, thunderous serves; it had absolutely everything. Many people were just left to laugh at how good it was because they could not quite believe it.
Entertainer of the year
My man is Alexandr Dolgopolov. He is the fastest player I have ever seen on a tennis court, and his movement is quite staggering. He doesn't care too much about his shot selection; he simply plays the match as he feels moved to in the moment which is very refreshing.
Whenever I see an order of play and I'm not quite sure where to go, I always head to the court Dolgopolov is playing on and I am very rarely disappointed. One knows that watching the Ukrainian play will never be boring, and it is unfailing entertaining.
He is a complete loose cannon, and it is wonderful to watch as he is one of the true characters of the game. Those around him may try to rein in his natural instincts, but I sincerely hope that he does not change and keeps that freedom.
In terms of his personality, he is always very relaxed and always looks as though he has just walked off the beach as he strolls on court.
He never looks nervous, and his shot-making is truly wondrous on both wings. His speed around the court is startling, and it is exhilarating to watch.
Most improved men's player
Mardy Fish will never receive the true recognition he deserves because he is neither flashy nor particularly distinctive in his play, but he has been the most improved player on the ATP Tour.
The American has completely reinvented his game and has become a real force on the men's tour. It was his wife Stacey who told him to get real, and as a result he revolutionised his diet to lose 15 kilos and got into incredible shape.
Fish now looks set to stay in the top 10 for a good while and he has firmly established himself as one of the hottest properties on the circuit. He has been in the shadow of Andy Roddick for a long time, but now he has come into his own.
Most improved women's player
It has to be Kvitova. She has made a stunning rise to prominence, and she will almost certainly be number one come 2012. There is not a realistically strong rival to the Czech right now, and she looks set to dominate.
I can see Kvitova going from strength to strength over the next 12 months, and the progress she has already made has been quite staggering to observe.
Frustration of the year
Still we have an astonishing amount of 'toilet breaks' which hold up the game, spoil the atmosphere of wonderful matches and infuriate opponents.
I realise that the players just want to relieve the tension and themselves in that situation, but they really have been taking the piss (pardon the pun) with it all year.
There is nothing more frustrating in the modern game, and the authorities must clamp down on it.
Champagne moments of the year
Umpire Eva Asderaki giving Serena Williams her richly deserved penalty for her foul-mouthed tirade was a stand out moment for me. The way the official stood up to Serena attempting to bully her and made the correct call was hugely impressive.
It will represent a pivotal moment in the umpire's career, and it was about time that an official stood their ground. The WTA need to get more control of the players, and Asderaki should be applauded for that. Many umpires simply would not have had the courage to do the same thing.
The other moment I would like to pick out was Roger Federer winning the World Tour Finals in London. The way the legendary Swiss came back towards the end of the year was wonderful.
I will be the first to admit that I wrote Federer off two years ago, but he has proved everyone wrong yet again. It was a very special moment.
I do not believe the standard at the top of the game is improving, and I know I am pretty much alone in thinking that. Federer can still win Grand Slams, and I hope he does so next year.
