Kuerten through to last eight

Ulihrach, who called on the services of a physio to massage his left thigh at 1-2 down in the third, dumped another routine forehand in the net as Kuerten sealed victory.

Kuerten will now meet either Arnaud Di Pasquale of France or Andrei Medvedev of Ukraine in Wednesday8217;s quarter-finals.

Agassi through

Andre Agassi played one of the great matches of his stellar career to beat defending champion Carlos Moya in four sets Sunday and advance to the quarter-finals of the French Open men8217;s singles.

The flamboyant American, fired up to win the only Grand Slam title that has eluded him, beat fourth-seeded Spaniard Moya 4-6, 7-5, 7-5, 6-1.

Agassi, a two-time beaten finalist here, trailed 6-4, 4-1 before his forehand caught fire and he turned the match around.

Agassi, without a Grand Slam title for over four years and the only American left in the men8217;s draw, matched Moya shot for shot in a compelling centre court battle and eventually broke his opponent8217;s will as Moya made increasingly numerous errors .

Moya maintained his unfortunate record of never having retained a singles title while Agassi moved to within three victories of becoming the first American to take the title here since Jim Courier in 1991-92.

Agassi8217;s win took him 2hr 30min and he sealed it with a typically audacious lob.He Left the court to a rousing ovation.

But 13th-seeded Agassi8217;s win was only one of two huge surprises on the slow redclay at Roland Garros.

Barbara Schwartz, an Austrian qualifier ranked 125th in the world, earlier sent fifth-seeded American Venus Williams tumbling out of the women8217;s singles.

Schwartz saved three match points in the second set before winning their fourth-round match 2-6, 7-6 9/7 6-3 in 2hr 14min.

The tall Austrian now plays top seed Martina Hingis of Switzerland, who beat Ruxandra Dragomir of Romania 6-3, 7-6 7/5.

Five-time champion Steffi Graf of Germany beat Russian teen Anna Kournikova 6-3,7-6 7/4 and now plays American second seed Lindsay Davenport. Third-seed Monica Seles and Spaniards Arantxa Sanchez-Vicario and Conchita Martinez also sealed places in the last eight.

Agassi was joined in the final eight of the men8217;s event by ninth seeded Marcelo Rios of Chile and unseeded Slovak Dominik Hrbaty.

Hrbaty, the man who knocked world number one Yevgeny Kafelnikov out of the tournament, beat Marat Safin of Russia 6-4, 3-6, 7-6 7/5, 6-3.

The 21-year-old has never previously made the quarter-finals at a Grand Slam, buT did well to negate the power and speed of Safin.

Hrbaty8217;s next opponent will be Rios, who recovered from two sets down to beat Spaniard Alberto Berasategui 3-6, 3-6, 6-3, 6-4, 6-3.

Lindsay Davenport, the US Open champion, beat erratic compatriot Jennifer Capriati 6-2 6-3 but will expect tougher resistance from veteran Graf.

Former Wimbledon champion Martinez 8212; unseeded at a Grand Slam for the first timein a decade 8212; sealed her spot in the last eight with a straightforward 6-2, 6-1 win over her compatriot Gala Leon-Garcia in 68min.

Martinez, a three-time semi-finalist here and winner of 18 clay court titles in her career, now plays Seles, who beat 16th-seeded Julie Halard-Decugis 6-1, 7-5 to end French interest in the women8217;s event.

Sanchez-Vicario, seeking her fourth French title, advanced to the last eight when her fourth-round opponent Mary Joe Fernandez of the US withdrew citing a groin injury.
