Arvidsson scored twice, Saros made 32 saves and the Predators defeated the Philadelphia Flyers 4-0 Tuesday.
Arvidsson played his fourth game since missing 21 contests with a broken thumb.
''It's a little hard to come back being out for six weeks,'' Arvidsson said. ''I feel like I'm close to where I want to be, I've just got to keep working.''
The shutout was Saros' second of the season and the sixth of his career.
''I've been practicing well and of course saw a lot of pucks today and we played pretty good defense, so that always helps,'' Saros said. ''When the team plays well in front of you, usually you get going too, and I had a little bit of luck, too, today, a couple of times the puck hit the post.''
Making his first start since Dec. 15, Saros was busy early, stopping 13 shots in the first period. He made 12 saves in the second and seven in the third period. His best sequence came just over three minutes into the second period when he made back-to-back saves in close on Sean Couturier and Jakub Voracek.
Michal Neuvirth made 26 saves for the Flyers, who have lost four in a row.
''We got a solid goaltending performance by Michal,'' Flyers interim head coach Scott Gordon said. ''All four goals, we beat ourselves on, putting ourselves in the wrong spots. You can't outscore those mistakes.''
Philadelphia did not convert on either of its power plays in the game. The Flyers have not scored with the man-advantage in their last four games.
''We hit two posts - lot of frustration,'' Flyers captain Claude Giroux said. ''We're going to keep working and the power play is going to get back untracked.''
Saros also denied Wayne Simmonds on a breakaway just under six minutes into the third. That save came just before Arvidsson scored his second goal of the night on a wrist shot from the slot at 6:15.
Smith scored the game's first goal at 2:03 of the second period.
Kevin Fiala skated the puck into the Philadelphia zone on the left side. From the left circle, Fiala sent a cross-ice pass to Smith at the right faceoff dot, where his wrist shot beat Neuvirth high to the stick side just underneath the crossbar.
Fiala has five points in his last three games.
Arvidsson made it 2-0 at 12:03 of the second.
In the left circle, Ryan Johansen drove toward the Philadelphia net before slipping a pass to Arvidsson, who was unchecked at the back post. He tapped it in for his second goal in as many games.
''He's pushing himself and you see how important he is out here tonight with his speed and his work ethic, his ability to score goals and make a difference in a game,'' Nashville coach Peter Laviolette said of Arvidsson. ''The line was really good, especially in the second and third period.''
Grimaldi scored his third of the season at 11:37 of the third. He has scored in consecutive games.
