Kings through, Ducks force game seven, Maple Leafs beat Bruins

Dustin Penner scored the winning goal with 0.2 seconds remaining in the second period as the Los Angeles Kings booked their place in the Western Conference semi-finals with a 2-1 victory over the St Louis Blues.

Drew Doughty opened the scoring for the Kings in the first and Chris Porter levelled 4:39 into the second, before Penner decided it with a stunning buzzer-beating effort which needed a replay to confirm it crossed the line in time.

The reigning Stanley Cup champions sealed a 4-2 series win and will next face the San Jose Sharks, who whitewashed the Vancouver Canucks.

Henrik Zetterberg scored an overtime winner as the Detroit Red Wings beat the Anaheim Ducks 4-3 to force a seventh and deciding game in their Western Conference quarter-final series.

Pavel Datsyuk and Daniel Cleary also scored for Detroit, while Kyle Palmieri scored for Anaheim.

Mike Ribeiro's overtime winner gave the Washington Capitals a 2-1 victory over the New York Rangers and a 3-2 series lead.
