MELBOURNE, Australia (AP) - If he could pick any player from any era to test himself against, Roger Federer would like a shot at Rod Laver or Bjorn Borg.

Laver, the last man to win all four major tennis tournaments in one season, was in the stadium that carries his name Thursday to witness top-ranked Federer dismantle Andy Roddick in the Australian Open semifinals.

After what he saw, Laver would just as soon stick to meeting Federer in the locker room - after the matches.

Federer likes to put on a show when Laver is at Rod Laver Arena and called his 6-4, 6-0, 6-2 victory over Roddick his best match here.
