WIMBLEDON, England (AP) Thirty years after their last spellbinding Wimbledon final, Bjorn Borg and John McEnroe are going head-to-head again - and this time, it's serious.

McEnroe unleashed his now famous You cannot be serious'' rant in that 1981 tournament, and the fiery American was tempted to use his trademark phrase again Friday as he revealed he had put his name to an underwear collection entitledBjorn Loves John.''

Borg's name has been emblazoned on underwear since 1997, when his brand was launched. Now, he's invited McEnroe on board to collaborate on a collection featuring two designs each, with the pair competing for the most sales.

I've been wearing his underwear for 10 years,'' McEnroe said.Now I finally have a chance to see if my name has any cache below the waist.''

McEnroe and Borg played each other 16 times in one of the sport's biggest rivalries, including in the finals of Wimbledon and the U.S. Open in 1980 and 1981. It was after his loss to McEnroe in the 1981 U.S. Open final that Borg suddenly walked away from the game at the age of 25.

McEnroe and Borg were eager to talk about their famous rivalry, both on the court and in underwear sales. Borg said the main characteristic he and McEnroe had in common was that ``we hate to lose.''

McEnroe added: ``Since it's his company and his brand, I feel like my back's against the wall but I was told that I would have an equal opportunity to sell as many as him. This is a two-on-two battle as far as I'm concerned.''


BRITISH HOPE: Britain could still have a Wimbledon champion this year after 17-year-old Liam Broady reached the boys' final.

Broady beat Jason Kubler of Australia 6-4, 6-3 Friday to become the first British player to reach the boys' final since 2004. Stanley Matthews, the son of the England soccer player of the same name, was Britain's last boys' champion in 1962.

Broady's match was finished before Andy Murray's loss to Rafael Nadal in the men's semifinals.

Broady said Murray's success had kept the attention away from him. That won't be the case when he faces another Australian, Luke Saville, in Saturday's final on Court 1.

I think I've done a lot better than most people would think to get here already,'' Broady said.So tomorrow especially I think I'll just go out there and just play my tennis and see what comes out of it.''

Broady has also advanced to the boys' doubles semifinals with Slovakian partner Filip Horansky.


DOUBLES: Bob and Mike Bryan were again taken the distance before reaching their fifth Wimbledon men's doubles final.

The No. 1-ranked American twins beat Michael Llodra and Nenad Zimonjic 6-4, 6-4, 6-7 (8), 6-7 (4), 9-7 Friday in the semifinals. In the third round, they won 16-14 in the fifth set against Jurgen Melzer and Philipp Petzschner.

The 2006 champions, who have also been runners-up three times, will face eighth-seeded Robert Lindstedt and Horia Tecau in Saturday's final. The Swedish-Romanian pairing lost in last year's final.

In women's doubles, Sabine Lisicki and Samantha Stosur were even 5-5 in the third set of their semifinal match against Marina Erakovic and Tamarine Tanasugarn when play was suspended because of darkness Friday.

That match will be completed early Saturday and the winners will meet second-seeded Kveta Peschke and Katarina Srebotnik in the final on Centre Court later in the day.
