TENNIS/French Open: After a night's rest and some time to reflect on how her fourth-round match could have unravelled in front of her eyes, Martina Hingis now contemplates one of the most attractive match-ups for the Roland Garros quarter-finals, against Belgium's Kim Clijsters.

Having broken off on Sunday night because of fading light, Hingis arrived on court yesterday morning for what was effectively a one-set shootout against a virtually unknown player six years her junior, Shahar Peer.

Hingis had never before played the 19-year-old from Israel, who had fought back from a set down on Sunday to draw level with the former world number one, leaving the match poised at 6-3, 2-6 overnight.

Hingis had seen how the younger player had lost all fear in the opening two sets and realised she was in danger of departing from the competition if the match continued with Peer clearly in the ascendant. It was the Swiss player who first voiced her concern about the light to the umpire, who, after a short discussion, abandoned for the night.

Yesterday, there was a new Hingis, aggressively determined to wrap up the match. Peer, who completed her mandatory Israeli army military training in November last year, had only played one previous French Open, in 2005, while Hingis had eight on which to draw, although the last was three years ago.

While she broke the teenager's serve in the first game, Peer immediately equalised. In all there were six service breaks, two of them against the Hingis serve. In the sixth game when the number 12 seed took a 4-2 lead, it appeared Peer's run was at an end but again the returns off the Hingis serve were hurting. While she had more shots and a cannier game plan than Peer in her locker, there will be concern that when Clijsters gets on the end of some of similarly paced serves, Hingis could find herself watching tennis balls fly by.

Typically, Hingis was unfazed by Peer's perky stubbornness to fold and took the third set 6-3.

"Yesterday it was difficult, difficult conditions," she said. "But I think for me it was better because she had the momentum and I could go out there fresh today. I'm happy to be in the quarter-finals again but scared of losing? She would have had to be closer for me to have been really scared."

While Hingis faces Clijsters, Justin Henin-Hardene meets an unheralded German Anna Groenefeld, ranked 14 in the world. The winners of those two matches then meet in the semi-finals.

In the other half of the draw 11th seed Venus Williams meets the 17-year-old who ended the run of world number one Amelie Mauresmo. Nicole Vaidisova has already made a name and with her power will hope to do the same to Williams as she did to Mauresmo. The winner will meet one of two Russian players in the other semi-final, Dinara Safina or eighth seed Svetlana Kuznetsova.
