Caroline Wozniacki regained the world number one ranking from Kim Clijsters when she reached the semi-finals of the Dubai Open with a 6-2, 6-4 win over Shahar Peer on Friday.
The top-seeded Dane was obliged to play on an outside court, under the lee of the giant Emirates building, next to a cosy row of trees, and with small spectator terraces containing a few hundred people.
This faraway court was the only place deemed safe for Peer, who last year became the first Israeli woman ever to compete in the UAE and who still requires constant guarding in areas separate from other players.
Now though Peer did not find her best ground stroking rhythm until she was a set and 0-4 down, and although she recovered to within a point of 5-5, Wozniacki's tenacious rallying sealed it.
Clijsters held the top spot for one week after winning the Australian Open last month and reaching the final of the Paris Open last week, and Wozniacki will now cling to the pinnacle at least until after the 12-day Indian Wells tournament which starts March 23.
But the rankings topper claimed she was far from overjoyed by her achievement. "I've said all along I wasn't sure about whether I could become number one this week, and that my focus really is not upon that. "For the moment it's more important to concentrate on what I have to do and try to win the tournament."
Wozniacki certainly did focus rather well. She began quickly, got her tactics right, made a crucial push at the end when her opponent was coming back dangerously and gained revenge for her loss to Peer here last year when she had also been the top seed.
Wozniacki's last game recovery began at 15-40 when she found some extra pace with a backhand cross court drive, forcing Peer to overhit, struck a steadier backhand cross court which Peer returned into the net, launched a winning first serve, and wrapped it up with a good net attack.
Earlier Wozniacki had directed much of her rallying down the middle area of the court, denying her opponent angles, and preventing Peer from using one of her great strengths - nimble lateral movement and excellent counter-hitting on the run.
It was only through sheer force of will that Peer got back into contention. There was no on-court TV interviews this time -- another safety precaution -- and it was in the haven of her special on-site living quarters that Peer unveiled her emotions. "I don't know why I started like that," she said. "I finished better than I started, but I made too many mistakes."
Was she relieved that her security ordeal was over? "I would prefer to be relieved in two days time," she said tersely. "I got wonderful treatment here. But it's my dream to come back here and to be able to play on the centre court."
