CHICAGO (AP) - Vladimir Tarasenko had two goals and an assist and St. Louis won an opening-night matchup of Central Division rivals.
Kevin Shattenkirk and Paul Stastny each had a power-play goal and two assists for the Blues, who eliminated the Blackhawks in seven games in the first round of the playoffs in April. Jake Allen had 17 saves in his first game since he became St. Louis' clear No. 1 goaltender with Brian Elliott's June trade to Calgary.
Richard Panik and Ryan Hartman scored for Chicago, which had six rookies in the starting lineup, including four playing their first NHL game. Corey Crawford finished with 29 saves.
SENATORS 5, MAPLE LEAFS 4 (OT)
OTTAWA, Ontario (AP) Auston Matthews needed 40 minutes to get into the NHL record book.
In the highest-scoring debut in modern NHL history, Matthews scored four goals for the Toronto Maple Leafs, but Kyle Turris scored 37 seconds into overtime to give the Ottawa Senators to a 5-4 victory Wednesday night.
Matthews got his fourth with 3 seconds left in the second period, bringing his mother to tears in the stands.
The 19-year-old from Scottsdale, Arizona, is the 12th first overall pick to score in his NHL debut.
Turris scored twice, including the tying goal 6:45 into the third period. Bobby Ryan, Erik Karlsson and Derick Brassard also scored for Ottawa.
Frederik Andersen stopped 25 shots for the Maple Leafs. Craig Anderson had 34 saves for Ottawa.
OILERS 7, FLAMES 4
EDMONTON, Alberta (AP) Connor McDavid scored two straight goals in the second period and had an assist, lifting the Edmonton Oilers over the Calgary Flames 7-4 on Wednesday night in the first game at Rogers Place.
Edmonton led the season opener 3-1 after one period on goals by Patrick Maroon, Tyler Pitlick and Zack Kassian. Alex Chiasson had a first-period score for the Flames.
Troy Brouwer and Michael Frolik scored in the second period to tie it 3-3, but then McDavid got goals with 7:43 and 5:27 left in the second for a two-goal lead - the second score came on a penalty shot.
Jesse Puljujarvi and Jordan Eberle scored for Edmonton in the third. Dennis Wideman had the final goal for Calgary.
Cam Talbot stopped 37 shots for Edmonton.
Brian Elliott made 21 saves in his first game with the Flames. Elliott was traded from St. Louis to Calgary in the offseason.
The Oilers moved into Rogers Place this year after 42 seasons at Rexall Place.
SHARKS 2, KINGS 1
SAN JOSE, Calif. (AP) Brent Burns scored the tiebreaking goal early in the third period after Los Angeles goalie Jonathan Quick left with an injury and the San Jose Sharks opened the season with a 2-1 victory over the Kings on Wednesday night.
Logan Couture added a power-play goal and an assist and Martin Jones made 21 saves in San Jose's first real game since losing the Stanley Cup Final to Pittsburgh exactly four months earlier.
Tyler Toffoli scored a power-play goal in a rough start to the season for the Kings.
Quick left after stopping 14 of 15 shots in the first period with a lower body injury. He appeared to hurt himself stretching to get to the post to stop a chance by Joe Pavelski late in the period. Jeff Zatkoff replaced him and stopped 15 of 16 shots.
After a high-paced opening period, the game settled down and it took a fortunate bounce for the Sharks to take the lead just over 3 minutes into the third. Joonas Donskoi tried to slide a pass to Mikkel Boedker but a sprawled out Drew Doughty blocked it.
Unfortunately for the Kings, the puck went straight to Burns, who beat Zatkoff for the goal that put San Jose up 2-1.
The Kings remained in the locker room as the Sharks played video highlights from last season - including the first-round win over Los Angeles - and unveiled the banner for winning the Western Conference for the first time in franchise history.
Los Angeles then jumped on top early, getting a power play just 33 seconds into the game and converting when Toffoli beat Jones high to the short side.
But the Sharks took over the play in the second half of the period and got the equalizer when Couture beat Quick from the slot on the power play. The referee initially ruled the puck hit the crossbar and Joe Pavelski and Quick got into a scrum as San Jose celebrated the apparent goal. After a replay review, the goal counted.
