Brian Elliott had another standout game in net, David Backes and Jori Lehtera had goals and the St. Louis Blues opened their first Western Conference final in 15 years with a 2-1 victory over the San Jose Sharks on Sunday night.
Tomas Hertl scored on a first-period deflection for the Sharks, who outshot St. Louis 32-23 but couldn't quite solve Elliott.
The Sharks were the best road team in the NHL in the regular season at 28-10-3, but have dropped four in a row on the road in these playoffs, including all three in the second round against Nashville.
They had seven goals in three road losses to the Predators and were 0 for 3 on the power play, which had been a major plus. San Jose had been converting on 33 percent of its power plays in the postseason.
Game 2 is on Tuesday night.
