BEIJING (AP) — Hilary Knight scored two first-period goals, Alex Cavallini stopped 12 shots, and the United States routed Switzerland 8-0 at the Beijing Olympics on Sunday in its final tune-up before facing arch-rival Canada.

Kelly Pannek and Jesse Compher also scored twice for the Americans, who close Group A play against Canada (2-0) on Tuesday. The U.S. improved to 3-0 and had 13 of 19 skaters earn at least a point.

The goal eruption came against a Swiss team which had been outscored by a combined 17-3 in losing its first two games, including a 12-1 loss to Canada on Thursday. It also provided the Americans some momentum a day after the they had 62 shots but struggled finishing in a 5-0 win over the Russian team.

Cavallini, who won an NCAA championship with Wisconsin in 2011, made her Olympic debut. Coach Joel Johnson has now rotated in all three of his goalies, with Nicole Hensley getting the shutout against ROC. Cavallini’s best save came 8 1/2 minutes into the second period, in getting across to her left to stop the Swiss on a 2-on-1 break.

Knight opened the scoring by driving to the net and converting her own rebound for a power-play goal 5:40 in. The game was essentially over when Compher, Knight and Pannek scored in a span of 2:11 to put the U.S. up 4-0 by the 16:15 mark of the first period.

Compher one-timed in Hayley Scamurra’s pass into the slot. Knight intercepted a clearing attempt at the left boards and beat Saskia Maurer on the short side. And Pannek collected a loose puck in the right circle and fired it in. Amanda Kessel then scored from a bad angle to make it 5-0 with 22 seconds left in the period.

Knight now has nine career Olympic goals to tie Monique Lamoureux-Morando for fifth on the U.S. list. And she increased her Olympic point total to 22, one behind Katie King, who ranks third.

The U.S., already missing top-line center Brianna Decker, averted a brief scare when forward Abbey Murphy limped off the ice after being tripped in the second period. Murphy returned to the ice a few minutes later. Decker broke her left ankle in a tournament-opening 5-2 win over Finland.
