United States will face Japan in the final of the World Baseball Softball Confederation Women's Under-19 Softball World Cup after they both claimed big wins in Irvine.
Hosts the US secured top spot in the Super Round table with a 100 per cent record as they completed shut-out victories in their final two matches at Bill Barber Park.
They defeated China 6-0 in the afternoon, before easing to a 9-0 win over Australia, called to an early halt after the end of the fifth inning.
Pitchers Montana Fouts and Alexis Kilfoyl were exceptional against the Chinese.
Fouts pitched four innings, allowing two hits with eight strikeouts, while Kilfoyl threw three perfect innings in relief.
Japan thrashed Mexico 11-0, which they realistically wrapped up at the end of a first inning after they scored nine runs.
The bronze medal match will take place between Canada and Australia.
Canada finished third in the table with a 5-4 victory over Puerto Rico, Grace Messmer coming on to pinch-hit and striking the winning run in the seventh inning.
Australia ensured their hefty loss to the US meant little after they hammered fifth-placed Chinese Taipei 12-3 earlier in the day.
Chinese Taipei had looked favourites to progress and were 3-1 ahead in the seventh inning.
But Australia roared through with 11 runs to give themselves a shot at the podium.
The tournament concludes tomorrow.
