Tomas Hertl, Logan Couture and Joe Thornton each scored two goals, powering the San Jose Sharks to a 6-3 victory over the St. Louis Blues in the NHL on Monday.
Thornton also had two assists as San Jose improved to 21-9-2 on the road, matching their total road wins from last season. At home, the Sharks are just 11-12-3.
The Blues lost goalie Brian Elliott to a lower-body injury in the first period. San Jose defenseman Matt Tennyson left in the first after he was driven into the glass.
Hertl had two of San Jose's three goals in the first. He also scored in the Sharks' 5-2 loss at Carolina on Friday.
Vladimir Tarasenko had a goal and two assists for St. Louis. David Backes and Jay Bouwmeester also scored.
Mike Richards scored his first goal in more than a year, leading the Capitals to the victory.
Alex Ovechkin put Washington ahead with his league-leading 39th goal of the season and had an assist. Evgeny Kuznetsov also had a goal and an assist for NHL-best Washington, which won its fourth straight and ninth in its last 10 games.
Defensemen Connor Murphy and Kevin Connauton scored for Arizona, which began a five-game East Coast road trip with its second consecutive loss. Louis Domingue made 31 saves.
Only seconds after Ovechkin's goal made it 2-1, Domingue appeared to have the puck covered with a glove in his crease when Washington's Tom Wilson reached a stick in to poke it away.
It found Richards, who rifled home Washington's second goal in 26 seconds. Coyotes coach Dave Tippett challenged the goal, but it stood.
Craig Smith scored the only goal in the shootout, lifting Nashville to the road win.
Viktor Arvidsson scored in the first period for the Predators (28-21-11), who are 3-0-3 in their last six games.
Brendan Gallagher scored his 16th goal for Montreal (28-27-5), which has recorded at least one point in its last five home games (4-0-1).
Nashville outshot Montreal 29-27 in regulation time and 30-29 overall.
Boone Jenner scored two goals and Scott Hartnell had a goal and an assist, leading Columbus to the road win.
William Karlsson, Brandon Saad and Dalton Prout also scored for the Blue Jackets, who avoided a sweep in the three-game season series by picking up a point for 10th time in their last 12 games (7-2-3).
Columbus goaltender Joonas Korpisalo made 26 saves.
Matt Beleskey and Loui Eriksson each had two goals for Boston, which continued its inexplicable home woes. Backup goalie Jonas Gustavsson made 29 saves.
The Bruins were coming off an impressive 4-2 road trip, but they were unable to build on that momentum back at home. Boston is 20-7-3 away from TD Garden, and just 12-15-3 at home.
