NEW YORK, Aug 29: Andre Agassi's retirement will have to wait a little longer after the eight-time Grand Slam winner battled to a 6-7, 7-6, 7-6, 6-2 victory over Romania's Andrei Pavel in the US Open first round on Monday.

At times looking like a maestro and others like the 36-year-old he is, Agassi needed three hours and 31 minutes to clinch victory in front of an adoring capacity crowd of nearly 24,000 at the Arthur Ashe Stadium.

A parade of seeded players won easily on the opening day of the tournament, including number nine Andy Roddick who overwhelmed Italy's Florent Serra 6-2, 6-1, 6-3 in just 75 minutes.

On the women's side, No 2 seed Justine Henin-Hardenne, No 4 Elena Dementieva and 10th-seeded Lindsay Davenport advanced to the second round.

There were few upsets at the National Tennis Center, with the notable exception of third seed Ivan Ljubicic who was ousted by Spain's Feliciano Lopez 6-3, 6-3, 6-3.

Regardless of how the unseeded Agassi fares in the tournament, his match against Pavel will surely be among the highlights of the 2006 Open.

After capturing the second-set tiebreaker 10-8 to level the match, Agassi had the momentum and looked to be well on his way to a second-round meeting with Cypriot Marcos Baghdatis.

But the 32-year-old Pavel, who had an 11-17 record in 2006 and had not played a hardcourt match since March, silenced the crowd by breaking Agassi's serve in the opening game of the third set and racing into a 4-0 lead.

Agassi, however, refused to quit and reeled off the next five games before forcing a tiebreaker which he won 8-6.

With the raucous crowd cheering his every shot, Agassi rolled over a battle-weary Pavel in the fourth set to win his sixth match over the Romanian in seven career meetings.

Agassi, the double US Open champion who will retire after the tournament, will have some well-earned time off to prepare for the eighth-seeded Baghdatis on Thursday.

Roddick, the 2003 Open champion, served notice that he is primed for a run at another title by whipping Serra under the watchful eye of new coach Jimmy Connors.

Roddick will face Kristian Pless of Denmark or Alberto Martin of Spain in the second round.

Henin-Hardenne overwhelmed Italy's Maria Elena Camerin 6-2, 6-1 in 74 minutes, just two days after capturing the New Haven title in her only tournament since Wimbledon.

Advancing along with Henin-Hardenne was Davenport, who showed no signs of the shoulder injury that forced her to retire from the New Haven final.

The 1998 champion needed just 52 minutes to stop Czech Klara Zakopalova 6-1, 6-4.

Dementieva advanced with a 6-1, 6-4 victory over American Laura Granville, while number six seed and 2004 champion Svetlana Kuznetsova stumbled briefly but recovered to beat Germany's Sandra Kloesel 6-2, 2-6, 6-3.
