Canada Set to Upset Brazil in Davis Cup, Rubin and Dementieva in Second Consecutive WTA Final

World Group Semifinals:

Switzerland at Australia (Australia leads 2-1)
In a Davis Cup doubles instant classic, Australia's Wayne Arthurs/Todd Woodbridge edged Roger Federer/Marc Rosset in five sets Saturday 4-6, 7-6(5), 5-7, 6-4, 6-4 to give the homecourt Aussies the 2-1 lead in the tie. This forces the Swiss to win two on Sunday, a highly unlikely prospect. If Federer beats Lleyton Hewitt in the first singles Sunday, the Swiss may substitute George Bastl, who has given Mark Philippoussis problems in the past.

Argentina at Spain (Spain leads 2-1)
Argentina stayed in the tie Saturday when Lucas Arnold/Agustin Calleri took out Alex Corretja/Al Costa 6-3, 1-6, 6-4, 6-2 in the Saturday doubles. This leaves Argentina's Agustin Calleri, subbing for an injured Zabaleta, with the heady prospect of beating world No. 1 Juan Carlos Ferrero Sunday to even up the tie at 2-2, with the fifth match of Carlos Moya vs. Gaston Gaudio.

World Group Qualifying:

Belgium at Austria (Austria leads 2-1)
Ollie Rochus and Kristof Vliegen kept Belgium in the tie Saturday, winning their first point in the doubles over Knowle/Peya in four sets. Now Rochus must beat Koubek in the first match Sunday, with the recovering-from-injury Xavier Malisse possible making his first appearance in the if-needed fifth match against Jurgen "Tuna" Melzer.

Brazil at Canada (Canada leads 2-1)
Oh Canada! The Canucks took a 2-1 lead Saturday when Daniel Nestor/Fred Niemeyer beat Gustavo Kuerten/Andre Sa in four sets, giving them two shots on Sunday for a massive upset. First up Sunday will be Niemeyer vs. Kuerten, then Nestor vs. Flavio "Of the Day" Saretta.

Czech Republic at Thailand (Czechs lead 2-1)
The Czechs took the lead in the Saturday doubles when rookie Tomas Berdych and veteran Jiri Novak eased by Paradorn Srichaphan and Danai Udomchoke in straight sets. Now the Thai must win two on Sunday, an unlikely scenario, with Srichaphan vs. Novak, and Udomchoke vs. Bohdan "I Didn't Do It" Ulihrach. But as they say, anything can happen in Davis Cup, especially when it is in Thailand.

Belarus at Germany (Belarus leads 2-1)
The Belarusians put themselves in position for the upset by winning the Saturday doubles, with Max Mirnyi and Vladimir Voltchkov beating Nicolas Kiefer and Rainer Schuettler in four sets. Now Belarus needs just one win on Sunday, with Schuettler vs. Mirnyi, and Germany's Tomas Behrend vs. Voltchkov.

Great Britain at Morocco (Morocco leads 2-1)
The Brits delayed the inevitable Saturday, with Tim Henman/Greg Rusedski easily beating Hicham Arazi/Mounir El Aarej in straight sets. The Moroccans will put a cap in it Sunday, either with Younes El Aynaoui vs. Henman, or Arazi vs. Rusedski. Look for partying in the Moroccan streets to ensue.

India at Netherlands (Netherlands wins 3-0)
The Dutchman clinched this Leander Paes-less tie in the Saturday doubles when John van Lottum and Martin Verkerk beat Mahesh Bhupathi and Rohan Bopanna in four sets. Back to zonal play for the Indians, tough luck with Leander out with injury.

Romania at Ecuador (Romania leads 2-1)
The not-so-dominating team of Florin Mergea and Horin Tecau beat the Lapentti brothers 13-11 in the fifth set on Saturday to put Romania up 2-1, setting up a major upset on Sunday. The Romanians will need just one win, in either Romania's Victor Hanescu vs. Nicolas Lapentti, or Razvan Sabau vs. Giovanni Lapentti. Now we'll see what the heavy-partying Lapentti brothers are made of.

U.S. at Slovak Republic (U.S. leads 2-1)
The Bryan brothers made a successful Davis Cup doubles debut for the U.S. Saturday, beating Karol Beck and Dominik "The Dominator" Hrbaty in straight sets to put the U.S. up 2-1 in the tie. Andy Roddick can clinch it for the U.S. and avenge his Friday loss when he faces Karol Kucera Sunday, with the second match Hrbaty vs. Mardy Fish.

WTA REVIEW/PREVIEW
Shanghai has its No. 1 vs. No. 2 final, but it didn't come without perspiration in the Saturday semifinals. No. 2 seed Chanda Rubin gained her second consecutive tournament final with a 6-0, 5-7, 6-3 win over unseeded Akiko Morigami, and No. 1 seed Elena Dementieva outlasted No. 3 Ai Sugiyama 6-1, 3-6, 6-3. The final is a repeat of last week's Bali championship match, where Dementieva crushed the American in straight sets (career series tied 2-2). The doubles final will be all-unseeded in Sugiyama/Tanasugarn vs. Loit/Pratt.
