Destinee Hooker threw her arms around teammate Courtney Thompson in celebration after the U.S. women's volleyball team defeated the Dominican Republic to advance to the semifinals at the London Olympics.
Thompson started at setter in the straight-set victory over the Dominicans after team captain Lindsey Berg injured her left ankle in the team's previous match.
''Courtney's a quarterback,'' Hooker said. ''She went out there and took control of the game. She knows our rhythm and it was great to have her on the court.''
The U.S. women remained undefeated in six matches at the London Olympics with the 25-14, 25-21, 25-22 sweep of the Dominicans.
The top-ranked U.S. team, with six straight victories, will play South Korea. The other semifinal Thursday was set when both Japan and Brazil won their quarterfinal matches.
Berg's status is uncertain for that match. The United States is obviously not revealing too much about the injury because it would give their opponents a competitive advantage.
''It's day-to-day,'' U.S. coach Hugh McCutcheon said of Berg's injury. ''I thought Courtney did a great job. I don't think we missed too many beats tonight.''
Hooker scored 19 points for the United States, which has never won a gold in indoor volleyball. The team took silver at the 2008 Beijing Olympics after falling in the final to Brazil.
The United States jumped out to a 12-3 lead and rolled through the first set, winning it on Foluke Akinradewo's block.
While clearly overmatched, the Dominican Republic took an 8-6 lead in the second set. The United States regained the lead when Hooker's spike made it 11-10. The Dominicans denied the U.S. set point three times, but Jordan Larson spiked to win it.
The U.S. took an 18-12 lead on Christa Harmotto's spike, but the Dominicans closed to within 19-18 before the Americans won it on Bethania de la Cruz de Pena's misplayed kill.
