Roddick moves on in straight sets

Andy Roddick defeated Andreas Seppi, 6-2, 7-5, 7-6 and will move on.

His serve was tremendous. He only was broken by Seppi once all match.

I think this is Andy's year. He's more positive and he's fresh, having not played in either the French Open or at the Olympics in Beijing.

Onto the round of 16.

Roddick takes first set

A-Rod won the first set agaainst Andreas Seppi, and has already broken Seppi once in the second. Seppi is obviously overmatched.

Andy, meanwhile, looks strong and seems destined for a straight sets victory barring a dramatic turnaround.

Muller takes out Amalgo

Qualifier Gilles Muller of Luxemborg is moving on to the round of 16.

The qualifiers are playing brilliantly here this year. In fact, Muller is second among the men in aces with 86.

Andy Roddick has taken the court here at Arthur Ashe against Andres Seppi, who is playing for the first time on the biggest stage in tennis.

Jelena recovers

Jelena Jankovic has moved onto the quarterfinals here, but not without considerable drama.

She dropped the second set to Caroline Wozniacki, 2-6. Then she cruised in the third, defeating her opponent 6-1 -- it took a total of 2 hours and 20 minutes.

She'll play the winner of Sybille Bammer and Marion Bartoli, now in progress.

Five-setter brewing on Grandstand

Nicolas Almagro and Gilles Muller are going to five sets on the Grandstand. Amalgro won the first two sets but Muller has come back, just forcing a fifth.

We'll keep you posted.
