Kyle Turris' goal helped the Ottawa Senators beat the visiting Washington Capitals, 3-1, on Monday night and earn their first winning streak in 51 days.
Mika Zibanejad and Clarke MacArthur, with an empty-net goal, also scored for Ottawa (17-18-7). Craig Anderson stopped 34 shots.
Joel Ward scored the lone goal for the Capitals (20-15-5), who have lost back-to-back games. Phillip Grubauer, in his fourth straight start, made 35 saves.
Ottawa took a 2-1 lead on Turris' 10th goal of the season. He cut through the Washington defense and deked Grubauer to open up the left side of the net.
Colin Wilson had two goals and an assist, and Mike Fisher scored a goal and helped set up two others in the host Nashville Predators' 6-4 victory over the Detroit Red Wings.
Fisher has three goals and three assists in Nashville's last two games. Craig Smith, Nick Spaling, and Roman Josi also scored.
Justin Abdelkader, Pavel Datsyuk, Drew Miller, and Patrick Eaves scored for the Red Wings, who have lost two of three.
The teams combined for five goals in a back-and-forth third period, but Nashville never relinquished the lead.
Wilson put the Predators ahead 1 minute, 54 seconds into the game with a wrist shot from the high slot that beat goalie Jimmy Howard.
Antti Raanta made 26 saves in his first NHL shutout and Brandon Saad scored as the host Chicago Blackhawks beat Los Angeles, 1-0, and sent the Kings to their first three-game losing streak in a year.
With Blackhawks No. 1 goalie Corey Crawford nearing a return from a lower-body injury, Raanta improved to 10-1-3.
The 2015 NHL Winter Classic will likely be held at Nationals Park in Washington, according to a person with knowledge of the situation, several media outlets reported.
Since the Capitals were named the hosts of the 2015 marquee outdoor game back in September, speculation over a venue - and whether the contest would take place within the District of Columbia itself - has been rampant given the number of stadium options in the region.
No formal decision has been made and an announcement isn't expected in the immediate future, the source said, but Nationals Park is the likely site after recent visits by NHL representatives to the ballpark, RFK Stadium and FedEx Field. An opponent remains to be determined for the contest as well.
