TORONTO — David Krejci  scored the third goal of a hat trick at 13:06 of overtime to give the Bruins a 4-3 win and put the Bruins, who now hold a 3-1 series lead, a win away from closing out the Leafs as the teams head to Boston for Game 5.
The Maple Leafs  took a 2-0 lead in the first period on goals from Joffrey Lupul and Cody Franson. The Bruins came back to take the lead in the second period thanks to a power-play goal from Patrice Bergeron  and a pair of goals from Krejci, the second of which also came on the man advantage. The Maple Leafs  answered Krejci’s go-ahead goal quickly, with Clarke MacArthur tying the game just 44 seconds later. The teams skated to a scoreless third period in which Toronto outshot Boston, 14-7. The Leafs held a 37-36 shots on goal advantage in regulation.
Tuukka Rask  made 45 saves, while James Reimer stopped 41 pucks.
WHAT WENT RIGHT FOR THE BRUINS
‘¢ Milan Lucic  kept up his impressive pace this postseason by picking up his eighth assist of the postseason. With eight points this postseason, Lucic now has as many points as he did in the first round the last three seasons combined, a span of 20 games.
Lucic had an injury scare late it the first period, as a puck from Zdeno Chara  was redirected and hit him somewhere in the face, causing him to bleed. The 24-year-old was back on the ice for the start of the second period, however, and was able to battle in front on his first shift, which allowed Bergeron to get to the rebound of Chara’s shot and fire it past Reimer.
‘¢ Speaking of Bergeron’s goal, the reigning Selke winner finally got his first point of the postseason with that tally. Brad Marchand  had an assist on Krejci’s first goal of the game, which gives the member of Bergeron’s line three points this postseason. Johnny Boychuk ‘s Game 2 tally remains the only one of those goals the line has been out there for.
‘¢ For the first time this series, the Bruins held the Maple Leafs without a power-play goal. That included rising to the challenge when Toronto got a 53-second 5-on-3 late in the second heading into the third as well as a third-period high-sticking penalty to Chara. The Leafs finished 0-for-4 on the power play after going 4-for-12 in the series’ first three games.
‘¢ The Bruins failed to capitalize on what was a nearly four-minute power play when Nazem Kadri cut Chris Kelly  on a high stick 58 seconds into the third period, toward the end of Gregory Campbell ‘s slashing penalty. However, the team still went 2-for-5 on the power play Wednesday after going 1-for-9 over the series’ first three games.
‘¢ Boychuk is a tough cookie. He looked hurt on two consecutive shifts after taking a puck off the knee and was limping very slowly down the tunnel in the second period. Despite the apparent pain he seemed to be in, he returned to the ice in short order. Still, that might be something to watch going forward.
WHAT WENT WRONG FOR THE BRUINS
‘¢ Krejci could have ended the game with under a minute and a half to play in regulation when Reimer knocked puck in front with his glove behind the net, but the puck was unsettled as Krejci tried to knock it in. Reimer got back in time to stop it, with Nathan Horton  failing to get a shot off on the rebound.
‘¢ Chara may have been screening Rask, but the Maple Leafs’ second goal sure was weak. Franson tossed a wrister on net from the point and it sailed past Rask without being redirected. Though No. 40 came up big for the B’s at points early on — it could have been 3-0 when it was 1-0 — those kinds of softies can’t be allowed frequently in the postseason.
‘¢ After all the Leafs’ complaining about the faceoffs in Game 3, the Maple Leafs held an 14-8 advantage on draws in the first period of Game 4. Bergeron won only one of the five draws he took in the first, while Rich Peverley  was 0-for-2 from the dot in the first 20 minutes. The Bruins bounced back, however, going 13-for-19 in the second period.
‘¢ There was a scary scene with around 12 minutes left in the third when Lucic raced to a puck in the Leafs zone and fired a slap shot that hit Mark Fraser in the head. Fraser went right down to the ice, grabbing his head and bleeding on the ice, while Lucic immediately went to check on the Toronto defenseman. Fraser left the game and did not return.
