Flavia Pennetta beats Roberta Vinci in the all-Italian women's singles final
Pennetta records a 7-6 (7-4) 6-2 victory
Britain's Jamie Murray and Australia's John Peers lose men's doubles final
France's Pierre-Hugues Herbert and Nicolas Mahut win 6-4 6-4
I'm just not sure about the adult ball-kids at the US Open - I can't get used to seeing fully grown men scurrying around after tennis balls. Do these people have to ask their boss for time off work to be a ballboy?
Mahut is looking a bit more relaxed on serve now, and four scudding deliveries see him through to a love hold.
The Murray/Peers combo look a lot more solid when the Scot is serving and the Aussie is at the net - Peers punches away a couple of crisp volleys as they get themselves on the board in the second set.

Jamie Murray is playing really well right now but it is all for nothing if you're not playing well together as a team. That last point Peers should have crossed after that great return from Jamie. I bet Jamie wishes Andy Murray was out there with him now.

So Murray and Peers with it all to do now - the French duo will have relaxed a little after taking that first set and that could make them very dangerous customers, with those long limbs swinging just a little more freely.
Herbert, who has been the most untroubled of the four players on serve, eases effortlessly through another service game.

I think Peers needs to step it up a little and let that first set go. As well as getting tight in that ninth game, he also got tight on his service game. But Mahut and Herbert returned well and were very aggressive in that final game.
*Mahut/Herbert 6-4 Murray/Peers
Big pressure now on the John Peers serve, and the Aussie immediately shows the strain with a double fault. Murray jogs across with a fist bump and a consoling word, but it makes no difference as his next serve is smashed down the line by Mahut.
The French duo then get the better of a rat-a-tat exchange at the net, and suddenly they have three set points . Murray sends a volley long, and in the blink of an eye, the first set is gone.

In the beginning both teams served well to get out of break points. In this situation when Murray and Peers had the opportunity, I think Peers got a little tight.
Image source, Getty ImagesNicolas Mahut has a reputation as a very solid server but Jamie Murray is causing him all sorts of problems with his sheer timing off the return. 15-30 quickly becomes 15-40 as the under-pressure Frenchman overcompensates with a double fault.
John Peers has a huge chance on the first break point but he knifes the volley into the net. A good second serve from Mahut gets him out of jail on the next point. The French pair close it out to raucous cries of 'Come on!'

The Murray serve into the Mahut backhand is working a treat - he's cramping the Frenchman for room and making it impossible to keep his returns away from the predatory volleys of John Peers at the net. Another good hold for the Scot.
Herbert is not especially tall at 6'2", but he seems much bigger than he is, such is his prowess at using every inch of his height. He gets real pop on his serve and is adept at reeling in those big overheads from almost behind him with his long arms. Another easy hold, despite a blooper of a missed smash from Mahut.

Quote MessageHerbert has proved once again in this tournament that he is a talent, something the French Davis Cup team overlooked against Britain in July. The Frenchman was left out of the doubles in place of Tsonga, who teamed up with Mahut in defeat by the Murray brothers. Herbert spent the weekend watching, and briefly talking to BBC Sport. Lovely chap, excellent English.
Image source, Getty ImagesWhoa there - Herbert uses his long levers to good effect to absolutely muller one down the tramlines, and another flash of his spidery limbs sees a return fizz past Jamie Murray for 30-30. Murray nets with a volley, and suddenly it's break point.
A good serve from John Peers fends that one off, and that's as close as Mahut/Herbert get.

Quote MessageIf you're not nervous ahead of a final of a Grand Slam then you're not human. Both teams started with jitters and Peers and Murray worked through it as a team. But both teams are through the nerves now. I like Murray and Peers because of the lefty-righty combo.

Mahut is sporting some absolutely epic sideburns today - proper mutton-chops, like a courtier in a Louis XIV period drama. His second service game is a much more straightforward affair than his first - a couple of returns fly long, and with that any chance for Murray/Peers to make an impression on the serve is gone.

Quote MessageThe stadium is starting to fill up. One lady has brought in her lunch and is about to tuck into spaghetti bolognese. That could get messy.
Jamie Murray ensures normal service is resumed with a fuss-free service game. John Peers snakes out an arm at the net to swat away a volley. Mahut frames one, and another deft volley from Peers closes the hold.

Quote MessageYou see doubles players making hand signals but they don't have that many - although it seems like they do have a lot when you're watching. They are giving signals about where to serve and whether the net player is going to poach or keep their position.
Herbert has got a howitzer serve and this is a much more straightforward service game after the drama of those first two games - some big unreturnables secure a love hold for the French pair.

Quote MessageMurray and Peers are doing a great job together - they are even colour coordinated with their kit. I think that helps in these big matches.
