BOSTON (AP) -- Boston's fourth straight win over Toronto has both teams going in opposite directions.
"A definite change from the way we were playing earlier in the year," Bruins goalie Tim Thomas said. "It seems like we step up our game when we play against them."
Thomas had 23 saves for the Bruins, who won for the fifth time in six games. The Maple Leafs lost their sixth straight and have only two wins in their last 11.
"When the losses add up like they have, we've got to find a way to right the ship," Maple Leafs defenseman and former Bruin Hal Gill said.
"They [the Maple Leafs] are having a tough time right now," Stuart said. "We have a lot of confidence right now and our goaltending has been a huge part of that."
Bergeron added an insurance goal with 1:19 left for Boston.
Toronto scored only one goal against the Bruins for the fourth straight game. The teams were playing for the fifth time in 28 days.
"We have to compete harder," Maple Leafs coach Paul Maurice said. "Every guy has to finish more checks, control rebounds and have more ownership of our situation."
The Maple Leafs' struggles in the third period continued; the team has been outscored 18-2 during its losing streak and had blown a pair of two-goal leads in the final period the previous two games.
Stuart got Boston even at 1-1 with 9:47 remaining when his wrist shot beat Aubin over the right shoulder.
Jeff O'Neill scored the lone goal for the Maple Leafs. His slap shot caromed off the boards into the goal crease and he then tipped the puck into an open net while Thomas was out of position at the 5:04 mark of the second period.
Aubin hasn't won since Nov. 5 and has beaten the Bruins once in nine tries.
Stuart has five points in the last three games including two third-period goals in Boston's victory against Montreal on Monday.
Shean Donovan added two assists for Boston, which has yet to be shutout this season.
