It was not a comfortable victory for Clijsters

All the latest results from Wimbledon

Belgian duo Kim Clijsters and Justine Henin were less than impressive in joining the other leading women in the second round of Wimbledon.

Number five seed Clijsters was in erratic form against American Samantha Reeves and made to work hard before overcoming her gutsy opponent 6-2 7-6.

Clijsters took the opening set comfortably enough but Reeves refused to roll over in the second, going down 7-5 in a tense tie-break.

"I did not play my best tennis but it was good enough to go through, that's the most important thing," said Clijsters, who is striving to shake off the lingering effects of an arm injury.

Henin endured some serving troubles in the second set

"The injury is still there and I'll have another MRI scan after Wimbledon," she added.

Clijsters will meet Elena Likhovtseva for a place in the third round after the unseeded Russian saw off Italy's Roberta Vinci 6-3 6-2.

Henin, a surprise finalist last year, survived the loss of the second set to overcome American Brie Rippner 6-2 6-7 6-1.

The number six seed was pegged back after a bright start and the second set became a test of nerves with six consecutive service breaks from 3-3.

Henin twice served for the match but double-faulted on break point each time to lose the advantage and the resulting tie-break 7-4.

But the 20-year-old recovered her poise to run away with the decider and seal her passage into the second round.

She will next face Denisa Chladkova of the Czech Republic

"I don't think too much about what happened last year," Henin said. "It's going to be difficult to do better this year but I will try to go as far as I can."

Former Wimbledon finalist Monica Seles was merciless as she whitewashed unseeded Spaniard Eva Bes 6-0 6-0.

The 28-year-old, who lost to Steffi Graf in the 1992 final, was back to her grunting best as she demolished a player ranked 90th in the world.

It was a Wimbledon debut to forget for Bes, who looked suitably embarrassed when the Court Two crowd enthusiastically applauded a rare point won on the Seles serve.

Two British wild cards bowed out in disappointing fashion, Rachel Viollet managing just one game in a 6-1 6-0 defeat to Bulgaria's Magdalena Maleeva.

The 30-year-old, daughter of former Manchester United player Dennis, was always up against it against the 19th seed after losing the first four games.

But injury hampered Hannah Collin, who succumbed to Switzerland's Emmanuelle Gagliardi 6-1 6-7 (4-7) 6-2.

Collin lost the first set 6-1 but responded well in the second, winning the tie-break 7-4 to square the match.

But she sustained a leg injury that needed treatment when serving at 2-4 in the final set, and was unable to find the break required after the delay.

American Lisa Raymond, the 16th seed, is safely through to the second round after beating Katarina Srebotnik of Slovenia 6-4 6-2.

But the number 28 seed, Argentina's Paola Suarez, bowed out after succumbing to another American, Jill Craybas, 6-4 5-7 7-5.
