Ryan Getzlaf scored the tying goal in the third period and set up Corey Perry's second of the game at 4:14 of overtime as the Anaheim Ducks beat the Colorado Avalanche 4-3 on Sunday night for their sixth consecutive victory and 10th in 11 games.
The Ducks (13-2-1) have the NHL's second-best record behind the Chicago Blackhawks.
Teemu Selanne scored his 668th career goal, tying Luc Robitaille for 11th place on the NHL list. It also was his 250th power-play goal, breaking a tie with Phil Esposito for third place.
Defenseman Francois Beauchemin had a career-high four assists.
Anaheim improved to 8-2-1 after allowing the first goal, and eight of the Ducks' wins this season have been one-goal victories.
John Mitchell, Cody McLeod and P.A. Parenteau scored for Colorado, and Jean-Sebastien Giguere made 20 of his 35 saves in the second period against his former team.
Jonas Hiller, who pushed Giguere out of the starting job in Anaheim during the 2009-10 season, stopped 20 shots. He made consecutive starts for the first time since going 2-1 in the first three games of the season.
Hiller missed three games because of a lower-body injury before returning Monday in a 3-2 win against Columbus.
Coming off a five-day break and playing in front of their fourth sellout crowd of the season, the Ducks didn't get a shot on net during the first 5½ minutes and fell behind 2-0 against a team that lost to Los Angeles on Saturday.
Anaheim turned it on in the second period and tied it before Mitchell put Colorado back in front. Getzlaf pulled the Ducks even again during a power play.
Colorado had only one shot in the third period and one more in overtime.
Giguere, who kept the Ducks at bay during a 53-second, 5-on-3 power play early in the second period, stopped Anaheim's first 12 shots before Perry converted Getzlaf's centering pass at 6:59 of the second. Selanne then scored his fifth goal while Colorado's Jan Hejda served a charging penalty.
Mitchell halted Anaheim's momentum 40 seconds later, using newly acquired defenseman Ben Lovejoy as a screen and beating Hiller from the slot to put the Avalanche back in front.
Colorado opened the scoring at 2:28. The Ducks, who came in with the second-worst penalty-killing percentage in the NHL (74.1), fell behind 2-0 after center Nick Bonino received a double minor for cutting Chuck Kobasew with a high stick at 9:42 of the period.
Parenteau cashed in on the ensuing power play, converting a rebound of Tyson Barrie's slap shot. It was Parenteau's eighth goal and first in eight games after a three-game stretch in which he scored four times.
