ADELAIDE, Australia (AP) _ Pat Rafter and Mark Woodforde won the doubles Saturday as Australia clinched the best-of-5 Davis Cup quarterfinal 3-0 against Germany and secured a berth in the semifinals.

The Aussie doubles combination seemed to be coasting as they won the first two sets before Germany's David Prinosil and Marc-Kevin Goellner fought back to level the match at two sets apiece.

The last two sets went 29 games without a service break until Prinosil, who lost a marathon singles five-setter against Wayne Arthurs on Friday, dropped serve to give Australia a 6-3, 6-2, 2-6, 6-7 (4), 10-8 victory.

Australia, the defending Davis Cup titlist, had a 2-0 lead after Lleyton Hewitt and Arthurs won the opening singles matches Friday.

The reverse singles will be played Sunday.

Australia will play the winner of the quarterfinal between Brazil and Slovakia in a semifinal at Brisbane in July. Brazil and Slovakia were level 1-1 after the opening singles matches.
