MELTTENNIS on Twitter: " @petenorfolk, beat Johan Andersson 62 62 in 58 mins in the first of his three round-robin quad singles matches at US Open NY."
Yep - great to see Peter back in action playing in the first of his three round-robin quad singles matches.

Wawrinka 0-1 *Youzhny
The Swiss star winds up his serving arm and gets things going. No fireworks and it goes to 30-30 but a third point in a row for the Russian gives him a break point already. A big big serve gets him back in it. Relief for the Swiss fans. Wawrinka makes a rare trip to the net and he blows it. First blood goes to the Russian.

2039: Not long to go now. Wawrinka to serve. Is Youzhny the favourite? Wawrinka could be a little battle weary. After Murray's win, the Swiss survived five sets to beat Sam Querrey and there have been questions about a leg injury. Will his Swiss pins hold out? Wawrinka said: "It's gonna be difficult for me. I will see how I'm gonna be with my leg and how I can rest for Thursday, but I will be focused more on myself than him." Bring it on. Head-to-heads, it's 2-2. They last played each other in Miami this year, with the Russian coming through 1-6 7-6 (7-5), 7-5. My mystic prediction ball tells me it will be Youzhny in four sets tonight. Dare you question my forecasting powers?

2037: Without further ado. I just wanted to say that for fun. As the US Open reaches a dramatic weekend, I want your thoughts, opinions and banter. I'll be with you for his encounter before Piers Newbery picks up the baton for Nadal. So what are you waiting for? Talk to me... Tweet me @bbcsport_mark, text me on 81111 (UK) or +44 7786200666 (worldwide) with TENNIS before your message, or get bantering on 606.

2036: So here we go. Youzhny vs Wawrinka. They're warming up in the Big Apple which is a 'cool' 21 degrees. How do you see this going? Youzhny is gunning for another semi-final place, four years after making the last-four in New York. Wawrinka is in his first Grand Slam quarter. Did you know that Wawrinka played alongside Roger Federer to win Olympic gold in the doubles in Beijing two years ago? And of course, Wawrinka was the man to snuff out Andy Murray's latest quest for a Slam title a few days ago.

HibaMS on Twitter: "Re:2015 Was gutted, but the great speeches and the generous donation by the Bryan brothers to flood relief have made me happy."

2032: Quick round-up on earlier proceedings. First up today on Arthur Ashe was a storming three-setter semi-final in the women's doubles. Sixth seeds Vania King and Yaroslava Shvedova (USA/KAZ x6) saw off Cara Black-Anastasia Rodionova 6-3 4-6 6-4. Good old tussle that one.

2030: Wawrinka vs Youzhny. The winner plays Nadal or Verdasco in the battle of the Spaniards which is up later. Plenty of action already though to fill you in on. Britain's Laura Robson has sadly made her exit from the junior girls competition at the third-round stage. The 16-year-old eighth seed, a semi-finalist last year, lost 6-3 6-2 to American Robin Anderson. Oliver Golding will be flying the GB flag in the boys doubles a bit later alongside Jiri Vesely.

2028: But you know what? Despite my ramblings, today is not Roger day. That was last night following the smooth and steady demolition of Robin Soderling. Let's move on from Roger if I may. See it like dumping a partner via text. A little cold admittedly, yet swift and efficient. It's because there's another Swiss in town shaking his cow bell. A pretty good one at that. You know the one - the one who saw off the Muzz. Stanislas Wawrinka is taking on the mighty Russian Mikhail Youzhny and there's a semi-final place up for grabs. It's day 11 at the Meadows of Flushing. Are you onboard or what?

2024: As the boys get ready to stroll on to Arthur Ashe, a few thoughts for you. I can't lie to you. Roger Federer has been the most watchable tennis player on this planet in all the days I have walked and bounced around this land they call Earth. There was Beautiful Borg. Magical McEnroe. Sizzling Sampras. Luscious Lendl. Bouncy Boris. And now there's Rousing Rafa edging rapidly towards legendary status. But Fab Feds nicks it for me. Still. Just my opinion. Talk of a mad man? Just wanted to get that off my chest.

2021: It's more men's quarter-final action. Stanislas Wawrinka vs Mikhail Youzhny. Where do you think this one is going?

2015: Congratulations to American pair Liezel Huber and Bob Bryan who have just been crowned mixed doubles champions. They beat Kveta Peschke and Aisam-Ul-Haq Qureshi 6-4 6-4. Quite a few Pakistan fans out there who have been in touch will be gutted. On to the singles drama....
