PITTSBURGH — Alex Pietrangelo beat Matt Murray 1:15 into overtime to give the St. Louis Blues a 5-4 victory against the Pittsburgh Penguins in the season opener for both teams Wednesday night.

The Blues recovered after letting a two-goal, third-period lead slip away. Pietrangelo’s shot from the slot hit Murray and slipped under the crossbar for his second goal of the game.

Paul Stastny had a goal and an assist for the Blues. Brayden Schenn and Colton Parayko also scored, and Jake Allen finished with 34 saves.

Sidney Crosby and Conor Sheary scored 54 seconds apart in the third to tie it, but the Penguins couldn’t complete the comeback on a night the two-time defending Stanley Cup champions raised the franchise’s fifth Cup banner to the rafters at PPG Paints Arena.

Justin Schultz and Olli Maatta also scored for the Penguins. Murray stopped 28 shots.

MAPLE LEAFS 7, JETS 2: Patrick Marleau scored twice in his Toronto debut in an opener at Winnipeg, Manitoba.

Marleau, 38, signed with Toronto as a free agent after 19 seasons with San Jose. He has 510 career goals.
