Just when it appeared the competitive gap was closing between women’s hockey powers, the U.S. and Canada ratchet the bar even higher. The intensity of their rivalry and play were evident in a relentless, back-and-forth outing that featured three lead changes and eventually won by Canada, 6-5 on Danielle Serdachny’s overtime goal. Canada won its 13th gold medal and the game comes at a time women’s hockey is gaining a foothold in North America with the launch of the Professional Women’s Hockey League. Canada won its tournament record 13th goal, with the Americans have won 10.
