Brandon Tanev scored a short-handed goal in overtime, and the Pittsburgh Penguins handed the Colorado Avalanche their first loss of the season with a 3-2 victory Wednesday night.

Tanev swooped into the zone and threw a shot on goal that went between Philipp Grubauer's pads. Colorado forward Gabriel Landeskog knocked the puck into the net, giving Pittsburgh its fourth straight win for the first time since an eight-game winning streak last season.

Sidney Crosby and Jake Guentzel also scored for Pittsburgh, and Matt Murray made 26 saves.

The Avalanche, the NHL's last unbeaten team, looked to start the season with six straight wins for the first time since 2013-14.

Nathan MacKinnon and Matt Calvert scored for Colorado, and Grubauer stopped 30 shots.
