Hats off for the biggest day in tennis, Super Saturday at the hot and very windy US Open.

Ever since 1984, when an 18 year old Pat Cash opened the day with an epic semi final against Ivan Lendl, losing a tie break in the fifth after Lendl hit a lucky shot to save match point for Cash, and the program for the first time included both men's semis and the women's final, this day has always attracted tennis afficianados.

What's on today's menu?

First up is Nadal v Youzhny, followed by Federer v Djokovic, and culminating with Clijsters v Zvonareva.

Russian Misha Youzhny is in his first Grand Slam semi, a deserved reward for one of the most fluent shot makers going around. His one hand backhand is pure artistry, the men's equivalent of Justine Henin. Rafa Nadal has never been in a US Open final, so he may be uncharacteristically nervous to begin with, but I have to believe he'll have too much game and grunt for the Russian shot maker. Nadal in 4 sets.

Next up is Roger Federer, in imperious form after dismantling his French Open conqueror Robin Soderling, not forgetting US Open conditions are far more in Federer's favour due to his unique ability to make the tiny racquet head adjustments on the quicker hard courts. It is Roger's almost supernatural wizardry traits, whereas Soderling is a mere mortal. Djokovic is somewhere in between, also possessing gifted hands and, more relevantly than Soderling, boasting a win over Roger in a hardcourt Grand Slam (semis of the 2008 Australian Open). So Roger will need to be on song here, but I think that's a given on Super Saturday. Roger in 4.

The women's final in New York prime time is the toughest to pick. Clijsters is the clear favourite, after wins over Venus Williams and, prior to that, Sam Stosur. That was a match even Clijsters found winning a little perplexing. Stosur really had the match on her own racquet, as it's hard to believe that given she is now credited with the best serve in women's tennis, she was unable to hold it once in the third set. On the other hand, I've only once seen conditions this windy in New York, so it's not exactly conducive to an accurate ball toss, step one of any type of consistent serving.

Clijsters' opponent was expected to be Caroline Wozniacki, who had two big monkeys on her back to contend with. FIrstly there was the pressure of becoming world no.1 if she won the Open (overtaking the injured Serena Williams). Then there was the financial factor - as winner of the lead in US Open Series, Wozniacki was looking at a further one million dollar bonus if she won in New York. To be honest, that I think was too much stress for a potential virgin Grand Slam winner to bear, and she was bundled out in straight sets by Russian Vera  Zvonareva.

Let's not fall into the trap though of downplaying Zvonareva's chances. She was runner up at Wimbledon, thereby giving her the important experience of having played in a Grand Slam final. Then there's her impressive 2-0 head to head record over Clijsters in 2010 (at Wimbledon and Montreal).

So in weighing it all up, I'm  thinking Kim's 20 match fairytale in New York may come to an end. Zvonareva in 3.

Sunday is intriguing, as its the only occasion in Men's Grand Slam tennis where the players are a little cruelly scheduled to back up in 24 hours. I think we're likely to see a Federer Nadal final, and we remember the last time thay played a major final on hard court, the 2009 Australian Open. It was a 5 setter won by Rafa and it was a classic. This time I'm expecting the faster hard court conditions of New York as compared to Melbourne will be to Roger's liking. Federer in 4.
