TAMPA -- Darren Raddysh had an NHL career-high five assists, and Andrei Vasilevskiy made 25 saves for the Tampa Bay Lightning in a 7-0 win against the Philadelphia Flyers at Amalie Arena on Saturday.

Raddysh tied Mark Recchi (March 1, 2009, against the Calgary Flames) and Martin St. Louis (Nov. 18, 2010, against the Flyers) for the most assists in a game by a Lightning player, and set the team record for the most by a defenseman.

"This was a team effort and I'm glad ‘Raddy’ was rewarded," Tampa Bay coach Jon Cooper said. "He made some really great plays. Some were on the breakouts coming out [of the zone]. He deserved it, good for him."

Victor Hedman had two goals and an assist for the Lightning (34-25-6), who are 2-4-1 in their past seven games at home. Anthony Duclair had a goal and an assist in his Tampa Bay debut after being traded from the San Jose Sharks on Thursday. He has 10 points (six goals, four assists) in his past five games.

"I heard the 'Duke' chants, it was amazing," Duclair said. "I never thought I'd hear that from Tampa Bay Lightning fans. It's a great crowd and when I was an opponent it was always a tough building to play in. I'm just happy I'm on the other side of it now."

Defenseman Matt Dumba also made his debut with the Lightning, a day after being traded from the Arizona Coyotes. He was plus-1 with two hits and a blocked shot in 20:04 of ice time.

"I had to get the body going, but coming to a team like this is so exciting," Dumba said. "Those guys are fun to watch. It's nice to be on this side."

PHI@TBL: Vasilevskiy posts a 25-save shutout

Samuel Ersson gave up four goals on 15 shots and was pulled in the first period for the Flyers (33-24-8), who were 2-0-1 in their previous three. Felix Sandstrom made eight saves.

Philadelphia coach John Tortorella was assessed a bench minor for being on the ice and a game misconduct at 10:49 of the first period after disputing a penalty. Associate coach Brad Shaw replaced him on the bench.

"It's an emotional game at times, we all get elevated blood pressure, it's just part of the game," Shaw said. "That's not why the game didn't turn out our way."

Hedman gave Tampa Bay a 1-0 lead at 1:49 of the first, scoring from the high slot off a pass from Nikita Kucherov.

Nicholas Paul made it 2-0 at 5:55 with a power-play goal, putting in a loose puck after a scramble in front.

Conor Sheary extended the lead to 3-0 at 9:10 with a wrist shot that went off Ersson’s glove.

Point pushed it to 4-0 on the power play at 10:49, putting in a rebound from the low slot.

"I thought they won some battles,” Flyers forward Garnet Hathaway said. “The power-play net front is one we win a lot and that's two in the back of the net. We're clawing back early on. 4-0 in the first 10 minutes, it's tough ... but I thought we stuck together. We've got to put it behind us."

Duclair made it 5-0 at 15:42 of the second period on a tap-in at the left post off a backdoor pass from Steven Stamkos.

"Great speed by ‘Stammer’ there to win the puck battle, the puck was in the corner," Duclair said. "I just wanted to get to the net. I've seen him enough times making those backdoor plays. I didn't have to do much -- just put my stick on the ice and what a great pass."

Cooper said that Duclair is a blessed skater.

"He came as advertised," Cooper said. "When he's playing he can really add a dimension to our top six. And then he showed you his hands, especially on his goal. Not everyone can score that goal. It was a great pass by Stammer, and someone has to tuck that in and he did."

Hedman made it 6-0 at 7:33 of the third period, and Brandon Hagel scored a power-play goal at 8:16 for the 7-0 final.

"We came out with great energy,” Hedman said. “Duke and Dumba came in bringing a ton of energy and enthusiasm to the group. I think it's a sigh of relief for everyone with the (NHL) Trade Deadline (on Friday) behind you. This is our group now and we just want to move forward. One gear ahead and that's full steam."

Defenseman Erik Johnson made his Flyers debut after being acquired in a trade with the Buffalo Sabres on Thursday. He was minus-1 with six hits and two shots on goal in 19:57.

Forward Denis Gurianov, acquired by the Flyers in a trade with the Nashville Predators on Thursday, had three shot attempts in 13:22 in his Philadelphia debut.
