WIMBLEDON, England (AP):

Roger Federer may not want to peek too far ahead in the Wimbledon draw. Waiting in the semi-finals could be the dangerous Novak Djokovic.

Even the first round could be tricky for the five-time champion, who will face a player he's never beaten before.

Federer got a challenging draw yesterday in his bid for a sixth straight Wimbledon title. He'll open against Dominik Hrbaty - a 30-year-old Slovakian playing in his 45th consecutive major - in the first match on Centre Court on Monday.

Hrbaty beat Federer in their only two previous matches in 2000 and 2004, but has slid from No. 12 in the rankings to No. 272 since their last meeting.

Presuming he overcomes Hrbaty, Federer could face a third-round match against rising French star Gael Monfils, whom he beat in the French Open semi-finals and either 2002 champion Lleyton Hewitt or Fernando Gonzalez in the fourth. Federer's projected quarter-final opponent is Spain's fifth-seeded David Ferrer. And then there's No. 3-ranked Djokovic, who beat Federer in the Australian Open semi-finals to end the Swiss star's winning streak there and was drawn in the same half of the bracket yesterday.

Size, power and overall game

Djokovic has the size, power and overall game to challenge Federer's supremacy.

Second-ranked Rafael Nadal, who lost to Federer in the past two finals, is in the other half of the draw. He could face two-time runner-up Andy Roddick in the semi-finals.

In the women's draw, top-seeded Ana Ivanovic and two-time champion Serena Williams are in the same top half. No. 2 Jelena Jankovic and Venus Williams, the defending champion and four-time winner, are in the bottom section.

Venus, seeded No. 7, will open her defence of the women's title against British wild card entry Naomi Cavaday. Williams could meet Sania Mirza in the third round, Daniela Hantuchova in the fourth, Jankovic in the quarters and 2004 champion Maria Sharapova in the semi-finals.

The Williams sisters could meet in the final again.

Ivanovic, who took over the No. 1 ranking after winning the French Open for her first major title, faces Rossana De Los Rio of Paraguay in the first round. She could face Anna Chakvetadze in the quarter-finals and either Serena Williams or No. 4 Svetlana Kuznetzova in the semis.

Serena Williams could face 2006 champion Amelie Mauresmo in the fourth round and either Kuznetsova or last year's runner-up, Marion Bartoli, in the quarters.
