LOS ANGELES -- Jeff Carter scored his second power-play goal on a deflection of Mike Richards' shot 28 seconds into overtime, and the Los Angeles Kings blew a three-goal lead before beating the Ottawa Senators 4-3 on Wednesday night.
Dustin Brown scored twice during the Kings' three-goal first period, and Carter had three points in Los Angeles' sixth straight home victory over Ottawa in the past decade.
Milan Michalek scored the tying goal with 4:27 left in regulation for the Senators. Jean-Gabriel Pageau netted his third career goal in the second period, and Bobby Ryan scored his first goal with Ottawa early in the third.
Jonathan Quick made 22 saves for the Kings. Richards and Anze Kopitar had two assists apiece.
Carter scored the winner during 4-on-3 play in the final second of Clarke MacArthur's hooking penalty from late in regulation. Richards teed up a shot that might have banked off an Ottawa stick before it was redirected by Carter in front.
Craig Anderson stopped 28 shots as the Senators opened a four-game Western road swing that is part of their season-opening six-game trip. He has one win in 11 career decisions against Los Angeles.
Ryan, the longtime Anaheim Ducks forward, scored during a power play early in the third period of his first game back in Southern California since he was traded north. Kings fans booed him loudly out of habit.
Ottawa captain Jason Spezza sat out to rest a persistent groin injury, leaving his team without its top-line center. Senators coach Paul MacLean wants his most accomplished scorer healthy for the rest of their trip, which includes back-to-back games in San Jose and Anaheim this weekend.
Stephane Da Costa replaced Spezza on the Sens' first line between Michalek and Ryan.
Brown got the Kings' first goal moments after he stepped out of the box from serving a penalty for interfering with Anderson, his fellow U.S. Olympic team hopeful and former teammate with the OHL's Guelph Storm.
The Senators then committed a string of penalties, and Carter scored his third goal of the season off a scramble at the moment Los Angeles' first 5-on-3 advantage ended.
Los Angeles went up 3-0 on another goal by Brown, who deflected a pass from Carter in Anderson's crease right after another two-man advantage ended. Carter's assist was the first of the season for a prolific shooter who had just 10 assists in his first 67 regular-season games with Los Angeles since arriving in early 2012.
Ottawa answered early in the second period when Erik Condra controlled a loose puck and fed the 20-year-old Pageau for a one-timer that trickled past Quick. Pageau, who had a memorable postseason hat trick against Montreal last spring, was playing in just his 12th regular-season game.
Ryan trimmed the Kings' lead to one goal with a power-play score. Moments after Quick made a phenomenal stop on a point-blank chance for Da Costa, Michalek found a loose puck amid a tangle of legs in the high slot and fired it past Quick for his first goal of the season.
NOTES: Ottawa RW Chris Neil went to the dressing room in the second period after Kings defenseman Alec Martinez accidentally chipped the puck into his face. Neil returned later in the period. ... The Kings scratched D Jake Muzzin after a poor game against the Rangers on Monday night, activating Martinez for the first time this season. LW Daniel Carcillo made his Kings debut on a line with Carter and Richards. Colin Fraser was scratched. ... Los Angeles will begin a four-game road trip at Carolina on Friday night. Ottawa doesn't have its home opener until Oct. 17.
