Pavel Datsyuk banked in a shot from a bad angle off Chicago defenseman Nick Leddy for the winning goal 3 minutes 8 seconds into overtime, and the Detroit Red Wings beat the host Blackhawks, 3-2. After goalie Corey Crawford made two point-blank saves, Datsyuk got to the loose puck along the goal line to Crawford’s left, whiffed once and then snapped a rising shot that hit Leddy and bounded into the net.

That sent Chicago to a season-high fourth straight loss. Detroit’s Dan Cleary scored with 4:45 left in regulation to tie the game at 2-2 after Henrik Zetterberg fired a loose puck into traffic in front. Valtteri Filppula also scored for the Red Wings. Dave Bolland and Patrick Sharp scored goals 44 seconds apart early in the first period, but the Blackhawks lost for the fifth time in six games after a 9-1-1 run.

SENATORS 6, FLYERS: 4 Filip Kuba scored the go-ahead goal with 1:11 left, and host Ottawa beat Philadelphia to earn a split of their weekend home-and-home series. Kuba fired a slap shot from the left point past goalie Ilya Bryzgalov, and Nick Foligno sealed the win with an empty-net goal with 45 seconds to go. Colin Greening and Erik Karlsson scored earlier in the third period for the Senators, who erased a 4-2 deficit.

DUCKS 7, BLUE JACKETS 4: Corey Perry completed his fourth N.H.L. hat trick with an empty-netter in the final minute, and Teemu Selanne chipped in two goals as Anaheim beat visiting Columbus. Rick Nash scored twice for the Blue Jackets, whose record, 11-25-5, is the league’s worst.
