I know it's early days but before the big guns come out to play in an hour or so, why not chuck over some opinions on how Andy Murray is looking. Is he ready for a serious pop at a Grand Slam?

1643: Zvonareva storms back to lead 3-1. On Grandstand, it's 18th seed Aravane Rezai vs Beatrice Capra. (Currently 4-4). On Court 4 we've got Yanina Wickmayer (Belgium's 15th seed) vs Julia Goerges (currently 4-3). Out on Court 8 there is Albert Montanes (Spain's 21st seed) vs Carsten Ball. (4-4 so far)

1638: Soneji is on fire today and tells me Pablo Cuevas (Mardy Fish's opponent) plays football and likes his surfing. He's also a major supporter of a charity that campaigns against animal cruelty. Nice work Pablo. Soneji finishes up with "Cuevas means cave". Stunning. Cuevas meanwhile is serving at 3-2. I hope he doesn't inflict too much cruelty on Fish today.

1634: Zvonareva already a break up against Lisicki. 1-0. Few facts for you. The Russian will be 26 next week. Lives in Moscow. She made her US Open debut in 2002 where she made the third round. Her best achievement at Flushing Meadows was last year and 2004 where she got to the fourth round. Best Grand Slam results are 2009 semi-finalist at Aussie Open and of course runner-up at this year's Wimbledon. Since writing that, she's been broken back. That'll teach me. Sorry Vera.

1626: Here goes from my colleague Pranav Soneji: "Our Mardy (who's 6ft 2') was feeling a little…lardy at the end of last year, hitting the scales at 14.5 stones following knee surgery in September. Fed up with the spare tyre around his midriff, the Florida resident went on a drastic high-protein, low-carb diet, eschewing fizzy drinks, cheese, pizza, cheeseburgers and chips. Instead he filled his boots on vegetables and salad and consequently lost a stone-and-a-half - although it was far from easy. "We calorie counted down to every calorie," he said. "Before, I ate whatever whenever. Now, I try not to eat anything late. It got fun because I could see a difference really quickly. I got into it, and got pretty religious about it.''
Worthy of an American down flag in the best possible way. Great work Mardy.

1624: Before I pass on more details about today's schedule, I'm jumping into my chopper for a quick buzz around the Meadows of Flushing. On Arthur Ashe it's 7th seed and Wimbledon finalist Vera Zvonareva . On Louis Armstrong, there's Mardy Fish (19th seed) up against Pablo Cuevas. My colleague Pranav Soneji has pulled out a couple of interesting titbits about the American Fish. More on that in a sec.

1617: And there you were thinking the British flags weren't coming out today. How wrong you were. Remember Anne Keothavong? After losing to Yung-Jan Chan in three sets on Tuesday she was not a happy bunny but she's back later today in the women's doubles. Around 0200 in the morning by my reckoning.

1610: Here we go again and I want your thoughts. As always, where would I be without your contributions? On my own that's where and I don't need lonely - not today. Tweet me @bbcsport_mark, text me on 81111 (UK) or +44 7786200666 (worldwide) with TENNIS before your message, or join the banter on 606.

1610: Mr Murray obviously did pretty well clearing the first hurdle of Lukas Lacko on Wednesday. Next up for him is Jamaican Dustin Brown. Not today though but all thoughts on the Muzz are welcome. For all those needing a sweet dose of Murray then check out his latest BBC column.

1606: Who needs Andy Murray for a line-up? He's yesterday's fish and chip wrappers. Today will be as lively as a bag of crayfish or I'll give you your money back. First up is 7th seed Vera Zvonareva and Sabine Lisicki. Then it's Caroline Wozniacki against Kai-Chen Chang. Followed by Uncle Roger. The boy Federer is playing German Andreas Beck. The evening games see Maria Sharapova and Novak Djokovic shaking their stuff. That's just for starters. Enough for you to chew on for now? I don't want you getting US Open indigestion.

1557: Afternoon. The echoes of Andy Roddick's foot-fault outburst are still ringing around Flushing Meadows as the fourth day of the US Open gets going. Anybody up late enough to see it? I was safely tucked up in bed when A-Rod fired off against Janko Tipsarevic but it all sounded tasty. What fireworks will be in store for us today?
