EDMONTON, Alberta -- The Boston Bruins might not be a work in progress after all.
They already seem to be clicking just days after captain Joe Thornton was dealt away.
Tanabe won it just 30 seconds before the game would've gone to a shootout. Brad Boyes had a career-high two goals as the Bruins won their second straight since sending Thornton to the San Jose Sharks on Wednesday.
"You make a trade to make your team better," Bruins general manager Mike O'Connell said. "We hope this will continue."
After trailing 3-0 early in the second period, the Bruins fought back on a pair from goals from Boyes and one from Sergei Samsonov in a 5-minute span.
"We had a little talk between periods," said Tanabe, a defenseman acquired on Nov. 18 in a trade with Phoenix.
The Oilers finished their three-game homestand 1-2 to fall to 6-5-1 at Rexall Place.
"We're back feeling like we got run over by a semi right now," Oilers coach Craig MacTavish said. "We outshot them almost 2-to-1 and we must have outchanced them 3-to-1."
Harvey scored on a wraparound backhand in the Oilers' 16-shot first period, and Smyth followed up just over two minutes later with his team-leading sixth power-play goal. He stripped new Boston defenseman Brad Stuart of the puck behind the Bruins net and swept in a rebound off Pisani's point shot.
Pisani scored a power-play goal of his own to open the second period for a 3-0 Oilers lead. The Edmonton native followed with a goal in the third that required video review.
"There weren't any long faces because we knew we had a lot of time left," Boyes said.
Boston (10-13-5) began a three-game Western road trip with its only meeting against the Oilers this season. It was the Bruins' first visit to Edmonton since the 2002-03 season.
Rookie Hannu Toivonen made 36 saves in his second straight start for the Bruins.
"I had a couple of good stops, but too much bouncing around," said Toivonen, who improved to 6-2-3.
Both teams played outside their own conferences for the first time this season.
"It's easier to open up because we don't see much of the teams in the West and they can't hurt you in the standings," Tanabe said.
"It was an emotional 24 hours we had after the big trade," Toivonen said. "But you can't worry about it too much."
- The Bruins face Western conference opponents their next six games.
- Referee Kelly Sutherland took a headfirst dive to avoid Bruins defenseman Brian Leetch's slap shot in the second period.
