PRAGUE (AP) — Canada squandered a five-goal lead in the third period before John Tavares scored 15 seconds into overtime to give the defending champions a 7-6 win over Austria at the ice hockey world championship on Tuesday.

The Canadians led 6-1 but Austria produced an unprecedented five-goal final period to force overtime in a Group A game in Prague. Peter Schneider led Austria’s surge in the third with two goals and an assist.

Benjamin Baumgartner completed a two-on-one rush before Schneider scored from a tight angle to make it 6-3. Dominic Zwerger’s slap shot made it a two-goal game.

Schneider added his second with 4:04 remaining and Marco Rossi’s backhander tied it at 6-6 with 49 seconds left.

In overtime, Tavares carried the puck into the zone and snapped a wrist shot past goaltender David Madlener to clinch Canada’s third straight victory.
