BOSTON – Auston Matthews broke a scoreless tie in the third period, Kasperi Kapanen added another goal and the Toronto Maple Leafs hung on the beat the Boston Bruins 2-1 on Friday to take a 3-2 lead in their first-round playoff series.
With the goalie pulled for an extra skater, David Krejci scored for the Bruins with 43.7 seconds left, but Boston couldn't tie it.
The Maple Leafs, who have alternated wins and losses in the first five games, now have a chance to close out the series when it shifts back to Toronto for Game 6 on Sunday.
Frederik Andersen had 28 saves for Toronto. Boston's Tuukka Rask finished with 25.
Boston failed to convert on its three power plays, and Toronto was 0 for 1.
The Maple Leafs' goals broke up what had been a defense-dominated game for 21/2 periods.
Matthews' fourth goal of the postseason came after he took a feed from Jake Muzzin and found an open corner of the net on a slap shot with 8:27 left. The Bruins challenged Matthews' goal, arguing Rask was interfered with, but the goal was upheld.
Kapanen got Toronto's second goal less than two minutes later, scoring on a wrist shot off assists from Andreas Johnsson and Morgan Rielly. Kapanen was also credited with an assist on Matthews' goal, along with Muzzin.
Toronto failed to covert on its power play in the third after the Bruins were nabbed for having too many men on the ice.
The Bruins were 2 for 2 on power plays in Game 4, propelling them to the win.
Both teams played conservatively and combined for only 13 shots on goal in the opening 15 minutes.
Rask smothered three loose pucks that hung around the net as part of seven first-period stops. Andersen had six saves in the first, his best coming when he turned away a tip-in opportunity by DeBrusk off a feed from Pastrnak.
