Theodore's scores late, Golden Knights beat Flames 5-3

Shea Theodore scored the tiebreaking goal with 1:10 remaining and the Vegas Golden Knights beat the Calgary Flames 5-3 Sunday night. Nick Holden had a goal and an assist for the Golden Knights (38-24-8), who recovered after giving up a three-goal lead and regained top spot in the Pacific Division over idle Edmonton. Tomas Nosek, Max Pacioretty and Jonathan Marchessault also scored for Vegas.

Making his third start for Vegas since being acquired from Chicago at the trade deadline, Robin Lehner made 19 saves to improve to 3-0-0 with his new team.

Milan Lucic had a goal and an assist for the Flames, who had won three straight. Dillon Dube and Matthew Tkachuk also scored for Calgary. David Rittich had 27 saves to fall to 0-6-1 in his last seven home starts.

On the go-ahead goal, Theodore's shot deflected off Calgary’s Andrew Mangiapane's stick and past Rittich into the top corner for his 12th.

Marchessault capped the scoring with an empty-netter with 18 seconds left for his 21st.

Trailing 3-0, Lucic got the Flames on the scoreboard as he snapped a shot through Lehner’s legs at 8:23 of the second period. It was his eighth.

Dube pulled Calgary within one 8:09 later as he beat Lehner over his blocker on the power play for his sixth.

Tkachuk tied it with 3 minutes remaining in regulation when he took a pass from Mangiapane before lifting a backhand shot past Lehner.

Nosek opened the scoring at 5:24 of the first period when he deposited a rebound past Rittich, who stopped the initial shot by Ryan Reaves but couldn't get back into position in his net to deny the follow-up attempt.

Vegas then went up 2-0 at 11:49 when Holden took a pass from Nick Cousins and snapped a quick shot past Rittich.

Calgary appeared to pull within one with a little more than four minutes to go in the opening period when Mikael Backlund swatted a rebound past Lehner, but the goal was disallowed after replays showed Backlund interfered with the goalie before scoring.

Pacioretty put the Golden Knights up 3-0 with a power-play goal at 3:39 of the second when he one-timed a pass from William Karlsson past Rittich.
