Sean Monahan scored two goals, Johnny Gaudreau had three assists, and Mike Smith posted his 37th career shutout as the Calgary Flames spoiled the Nashville Predators' home opener with a 3-0 victory Tuesday.
Elias Lindholm also scored for the Flames, who have amassed 10 goals while winning their last two games after a season-opening loss. Monahan has four goals this season, Lindholm has three, and Gaudreau has six assists.
Smith made 43 saves, including 21 in the second period when the Flames killed off two power plays, one when the Predators had a 5-on-3 advantage for the full two minutes. Smith had saved 34 of 42 shots in a home-and-home split against the Vancouver Canucks last week.
Predators goalie Pekka Rinne made 24 saves in the opener of a four-game homestand after Nashville won its first two games on the road last week. The Predators were not shut out at home last season while posting a league-high 117 points.
Lindholm gave the Flames a 1-0 lead on a power-play goal at 16:11 of the first period. Gaudreau stepped through the defence at the blue line and found Lindholm in the right circle, where his wrist shot hit the right post and caromed in.
Monahan scored another power-play goal for a 2-0 lead at 5:22 of the second period when he banged in a rebound of Matthew Tkachuk's shot from the right circle, giving Tkachuk his fifth assist of the season.
Monahan scored his second goal of the night 33 seconds into the third period. His shot from the left side on a 2-on-1 break deflected off Mattias Ekholm's skate past Rinne.
The Flames had both Tkachuk and Michael Stone sent off for tripping at 9:16 of the middle period. Calgary also killed off power plays later in the second period and in the middle of the third period.
Nashville first-line forward Viktor Arvidsson, who had two goals against the New York Islanders on Saturday, was struck in the face by the puck on his first shift. He eventually returned five minutes into the second period.
