Diana Taurasi scored 18 points and Tina Charles had a double-double to lead the Americans to an 88-61 win over the Czech Republic on Friday.
The Americans (4-0) have now won 37 straight games in the Olympics, including four straight gold medals. The U.S. started slow but looked fresh after its first day off since getting together on July 14 to start training for the London Games.
The U.S. had rolled through its first three opponents winning by 36 points a game and continued the onslaught against the Czechs (1-3), who will need to win their final game Sunday to possibly advance to the quarterfinals.
The Czechs jumped out to a quick lead scoring the first 10 points of the game in just two minutes. It was the Americans' biggest deficit in the Olympics since they trailed the Czechs 13-2 in the opener of the 2008 Beijing Games. They went on to win that game by 40 points.
"We had a little bit of a tough time getting shots to go in and the Czech Republic team did a great job of hitting their threes," U.S. forward Maya Moore said of the Americans' slow start. "We just try to stay agressive. It's about When the other team hits you, you gotta get back up and figure out a way to overcome it. And that's what we did."
The Czech Republic also played the U.S. tight for a half in the 2010 world championship gold medal game, trailing by five at the break. The U.S. won that contest by 20.
The Czechs led 26-24 after the first quarter after hitting six of their first 10 3-point attempts. They didn't hit another 3-pointer the rest of the game, missing their final 11 attempts.
While the Czechs went cold, the Americans heated up behind Charles — who had 16 points and 14 rebounds — and Tamika Catchings.
Trailing 30-26, the Americans scored 22 of the next 28 points to go up 48-36 with 2:18 left in the half. Catchings and Charles each had six points during the burst. Catchings' layup off a fullcourt pass from Moore gave the U.S. a 31-30 lead. After a Czech basket, Charles scored six straight and the U.S. never trailed again.
The Americans led 48-38 at the half and put the game away with a 20-3 run to start the second half. Taurasi hit two 3-pointers during the spurt.
The Czechs couldn't get within 20 points of the U.S. the rest of the way.
"Throughout the whole game I think our defensive intensity picked up," Catchings said. "The third quarter was probably one of the best third quarters we've had since we've been playing together. Now we've just got it going in the first half, start the game off that way."
Michaela Zrustova scored 15 points to lead the Czech Republic.
Sylvia Fowles sat out her third consecutive game to rest a sore left foot. She did participate in pregame warmups for the first time.
Even without their 6-foot-5 centre, the Americans controlled the boards, outrebounding the 61-40, including 27 on the offensive end.
While the U.S. has already clinched a spot in the quarterfinals, the Czechs (1-2) still are trying to advance.
They made a surprising run to the silver medal at the worlds, knocking off defending champion Australia in the quarterfinals before losing to the U.S. in the title game. The Czech Republic was definitely buoyed in that tournament by its home crowd that included President Vaclav Klaus for the championship game.
The Americans will close out pool play Sunday against China, which was routed by Turkey 82-55.
Also Friday, Australia's Liz Cambage had the play of the day — maybe of the Olympic women's basketball tournament when she dunked in the Aussies' 70-66 win over Russia. Canada advanced to the quarterfinals with a 79-73 victory over Brazil. Croatia routed Angola 75-56; and France edged Britain 80-77 in overtime.
