China 2 USA 1
China cruised to a win over USA in London after USA took an 11th minute lead when Paige Selenski slid onto a cross.
The hard-working Li Honxia hit back with her fourth goal of the tournament three minutes later and the the scores remained level until Mengyu Wang fired home from a 61st minute corner.
Jackie Kintzer had already denied Wang three times in the game on her stick side, before the tall full-back switched sides and struck low to the keepers left.
USA were left ruing a missed chance on the right post from Jill Witmer.
Argentina 4 USA 0
The world champions were far too strong for the USA as they continued their tradition of slowly improving through tournaments.
