Maple Leafs 4, Bruins 2: Joffrey Lupul scored a pair of goals and James Reimer turned aside 39 shots as visiting Toronto evened its Eastern Conference first-round series at one game apiece.

Phil Kessel scored what proved to be the deciding goal and James van Riemsdyk also tallied as the fifth-seeded Maple Leafs erased a 1-0 deficit with three unanswered goals to rebound from a 4-1 drubbing in the series opener. Game 3 in the best-of-seven series will be played Monday night in Toronto.

Nathan Horton and defenseman Johnny Boychuk scored goals and Tuukka Rask made 28 saves for the fourth-seeded Bruins, who pressed hard for the equalizer until van Riemsdyk converted a rebound for the insurance tally with 3:07 remaining.

Lupul countered Horton's opening goal by scoring twice in a span of just over 5 1/2 minutes in the second period. He pounced on a rebound of defenseman Jake Gardiner's shot from the point and chipped it into the net at 5:18 before taking a crossing pass from Matt Frattin and tucking a backhander past Rask at 11:56.

Kessel, who has labored to score against the Bruins since he was traded to Toronto, made it 3-1 on a breakaway 53 seconds into the third period. Boychuk cut the deficit in half with a blast from the point that deflected past Reimer with 9:25 to play.
