ATHENS, Greece (AP) - Lisa Leslie scored 25 points on 11-of-13 shooting, Tina Thompson added 18 points, and the United States hit South Korea with a big second half run to stay unbeaten. The Americans broke it open with a 19-2 run to start the second half.

Lauren Jackson had 31 points and nine rebounds as Australia, the 2000 silver medalist, remained unbeaten by dominating inside. The 6-foot-5 Jackson, the WNBA's MVP last season with the Seattle Storm, came into the game averaging 21 points. She had that many in the first 15 minutes against Japan.

Jana Vesela scored 22 points and Eva Viteckova added 20 as the Czech Republic beat China 98-83 Wednesday to avoid a third straight loss.

Russia held Brazil 40 points below its scoring average in the tournament, leaving Australia as the only unbeaten team in Group A.

SHOT PUT

ANCIENT OLYMPIA, Greece (AP) - Ukrainian Yuriy Bilonog took a flag-draped victory lap while American Adam Nelson stood in the shot put ring for three minutes, pointing at officials and pleading.

Nelson led the entire competition, but Bilonog's final throw tied Nelson for the best of the day at 69 feet, 5 1/4 inches. Nelson had one last chance to win and unleashed a great toss, but was called for his fifth consecutive foul.

Since Nelson had no other good throws and Bilonog had several, the Ukrainian won and left Nelson stunned at the ancient site that gave birth to the Olympics 28 centuries ago. Denmark's Joachim Olsen won the bronze at 69-1 1/2.

Earlier, thousands of spectators sitting on grassy slopes surrounding the pit watched Russian Irina Korzhanenko's winning toss of 69-1 1/4. Yumileidi Cumba of Cuba won the silver with a throw of 64-3 1/4 on her last attempt, and Nadine Kleinert of Germany took the bronze.

BOXING

Cuban heavyweight Odlanier Solis duplicated his three-point victory over Russia's Alexander Alexseev from last year's world championships by winning 24-21. Solis, Cuba's successor to three-time gold medalist Felix Savon, is a two-time world champion.

In another bout, Chinese light flyweight Zou Shiming outclassed American opponent Rau Shee Warren to win 22-19 and hand the U.S. team its first loss in Athens.

Devin Vargas joined six U.S. teammates in the second round with a 27-7 victory over Morocco heavyweight Rachid El Haddak.

SOFTBALL

United States 7, Canada 0

Taiwan 1, Italy 0

Australia 5, China 0

ATHENS, Greece (AP) - Jennie Finch pitched a one-hitter with eight strikeouts and Lisa Fernandez went 3-for-4 with a home run as the United States won its fifth straight shutout, beating Canada 7-0 to clinch a spot in this weekend's semifinals.

Crystl Bustos and Lisa Fernandez homered for the two-time defending gold medal-winning U.S. squad, which has outscored its opponents 31-0.

Hua Su Lin pitched a five-hitter to lead Taiwan to its second straight win after three opening losses. Fen Yan Weng drove in the game's only run while Natalia Cimin had two hits for Italy, which lost for the fourth time in five games.

Australia won its fourth game in five tries, with the only loss to the unbeaten United States. The Australians scored all the runs in the eighth, with two runs unearned. Taiwanese center fielder Yang Huichun said her team was tired from Tuesday's 2-0 win over Greece.

SWIMMING

ATHENS, Greece (AP) - The United States women swept the 800-meter freestyle relay, taking down the oldest world record in swimming while leaving Australia in their wake.

Kaitlin Sandeno swam the final leg and cruised to the wall in a time of 7 minutes, 53.42 seconds, easily beating the mark of 7:55.47 set exactly 17 years earlier by East Germany.

Natalie Coughlin, who led off the record effort, leaned over the edge of the pool and yelled to Sandeno, ''You did it!'' The other Americans, Carly Piper and Dana Vollmer, hugged each other on the deck.

No one was close to the Americans. China, more than 2 1/2 seconds behind, took the silver while Germany edged Australia for the bronze by just five-hundredths of a second.

Meanwhile, Pieter van den Hoogenband of the Netherlands repeated as the Olympic champion in the 100 freestyle, Japan's Kosuke Kitajima completed a sweep of the men's breaststroke events by winning the men's 200 meters, and Otylia Jedrzejczak of Poland won her third medal of the games with a victory in the 200 butterfly.

Another world record was set in the semifinals of the women's 100 freestyle. Australia's Jodie Henry won her heat in 53.52, lowering the mark of 53.66 set by Lisbeth Lenton at the Australian trials in March.

The fall of Communism brought to light evidence of massive cheating by the East Germans and tarnished that country's numerous athletic achievements - including the women's 800 relay record set Aug. 18, 1987.

Russia 3, Germany 0 (31-29, 25-11, 25-18)

ATHENS, Greece (AP) - A sluggish American start and some Dominican determination led to a big upset.

Milagros Cabral de la Cruz had the match-winning kill in the fifth set, giving the Dominican Republic a 26-24, 22-25, 27-25, 23-25, 19-17 victory over the United States.

Dropping to 1-2, the Americans must play Russia on Friday and Cuba on Sunday to close the preliminary round.

Cuba topped previously unbeaten China in five sets behind 24 points from Zoila Barros Fernandez. China, Cuba and Russia are tied for first in Pool A.

Ekaterina Gamova had 23 points, including 20 kills, to the lead the Russians past Germany in three sets.

In Pool A, So Yun Chang had 18 points to lead Korea to a sweep of Kenya. Tomoko Yoshihara had 16 points to lead Japan to a four-set victory over Greece.

The United States led 5-1 in the second minute of the last period after captain Heather Moody scored from 2-meters.

''From 5-1, no, we've never lost from there,'' said Moody, who has been on the U.S. team since 1996. ''It's hard, but it's the Olympics and that's the way it works - it happens.''

Russia is 2-0 after it rallied to beat World Cup holder Hungary, with captain Sofya Konukh scoring three goals.
