The US outshot Denmark 85-8, and broke the single-game shots on goal record, 82, the 1997 US team set in 1997 in a 10-0 win over Sweden.
With five points apiece, defenders Caroline Harvey and Haley Winn led the scoring surge. Just 57 seconds into the game, Taylor Fox began the rout, followed shortly after by Casey O'Brien. Jesse Compher and Hayley Scamurra's late goals sealed the victory.
Caroline Bjergstad made 20 saves in the third period after Emma-Sofie Nordstrom of Denmark stopped 51 shots in the first two. Gwyneth Philips clinched the shutout for Team USA and blocked Nicoline Jensen's late third-period penalty shot.
