Rask makes 21 saves, leads Bruins past Leafs for Boston's 13th win in 14 tries

BOSTON - Tuukka Rask stopped 21 shots Saturday as the Boston Bruins beat the Toronto Maple Leafs 4-1 to start December the same way they finished November.

Boston beat Toronto for the fourth straight time this season and the second straight game. Nathan Horton and David Krejci each had a goal and an assist for the Bruins, who have outscored their closest pursuer in the Northeast Division 23-6 this season.

Rask made his first start since the day after U.S. Thanksgiving, a 3-2 shootout loss to Detroit that was the only blemish on Boston's otherwise perfect November. He has won four of his last five, allowing a total of 9 goals.

James Reimer stopped 26 shots in his first game in the net since leaving an Oct. 22 game against Montreal with an injury that was not disclosed. He had not lost in regulation in his previous six starts.

Chris Kelly also scored for Boston, and Milan Lucic had a pair of assists. Mikhail Grabovski scored Toronto's only goal.
