KUMAMOTO — The United States tightened its grip on the FIVB World League's Pool B with a power-packed display, beating Japan 3-0 at Kumamoto Prefectural Gymnasium on Saturday.

The Americans' victory, by 25-17, 25-23, 25-15 scores, improved their win-loss record to 7-2 and left Japan at the bottom of the four-team group at 1-6.

Having won all six World League meetings between the two teams in 2006 and 2007, the United States looked hungry to extend that streak, especially after France, the nearest challengers, had suffered a surprise 3-2 defeat to Italy in Paris on Friday night.
