GLENDALE, Ariz. -- Cory Conacher scored at 2:48 of overtime to give the Ottawa Senators a 4-3 victory over the Phoenix Coyotes.
Positioned to the right of the Phoenix goalie Mike Smith, Conacher converted a perfect pass from Marc Methot at the left point into his second of the season and the game-winner.
The Ottawa win supported a hat trick from Jason Spezza, the Senators captain. Spezza scored in second to cut the Coyotes 2-0 lead in half, and then tied the game early in the third with a power play goal. That put Ottawa into a 3-2 lead until late in the game.
With Ottawa defenseman Chris Phillips in the penalty box for interference, Oliver Ekman-Larsson's blast from the left point was tipped in Mike Ribeiro with 3:30 left in the third period. That tied the game at 3 until Conacher picked up the game-winner in OT.
Down 2-0, Spezza's first goal of the game came at 8:42 of the second period.
Early in the third, Spezza capitalized on a giveaway from Smith. Failing to clear the puck behind his net, Smith gave up the puck to Colin Greening, who hit Spezza with a perfect pass in the slot. Spezza buried his second of the game and third of the season at 1:50 to tie the game.
Then, Spezza registered his third goal of the game at 7:19 of the third. The three goal game was his fifth career hat trick, and first since Feb. 14, 2012, at Tampa Bay.
Despite being widely outshot in the opening period, the Coyotes struck early in the second and created needed separation.
Rob Klinkhammer and Radim Vrbata scored within 1:23 early in the second period and the Coyotes jumped out to a two goal advantage.
First, center Antoine Vermette won the draw to the left of goalie Craig Anderson and fed Klinkhammer, who was in perfect position to rip in a shot from 10 feet in the slot.
Less than two minutes later. Mikkel Boedker dropped a pass in the slot for Vrbata and the 32-year-old deposited a wrist shot into the upper right corner of the Senators net. The goal was Vrbata's first since a hat trick on opening night at home against the New York Rangers.
Despite falling behind, the Senators came out as clearly a different team.
The Senators limited Phoenix to four shots in the opening period. The first shot came nearly 12 minutes into the game and that was a loose puck off the stick of Ribeiro that slid into the crease.
