Pennetta races through US Open

The in-form Flavia Pennetta was the first winner on day five of the US Open in New York.

The 27-year-old, who won the recent warm-up tournament in Los Angeles, part of 15-match winning streak, sauntered to a 6-1 6-1 victory over Canada's Aleksandra Wozniak in less than an hour.

Wozniak did not hold serve in the entire match. Indeed she won just 26 per cent of the points on her own delivery.

That meant Pennetta did not even have to play that well to progress - her first-serve percentage was a lowly 34 per cent.

Pennetta's good form has seen her become the first-ever Italian to crack the world's top 10 and she's now just one win away from equalling her best-ever run at a Grand Slam.

That came at Flushing Meadows last season when she made the quarter-finals. Pennetta will now face either Vera Zvonareva or Elena Vesnina for a place in this year's last eight.

Daniela Hantuchova, the 22nd seed, was also a straight-sets winner.
