Patrice Bergeron scored the tying goal with 9:24 left in regulation, then put Boston ahead in the shootout as the Bruins held on for a 3-2 victory over the Toronto Maple Leafs on Monday night.
Milan Lucic also scored for Boston, which rallied from a 2-0 deficit and improved to 11-2-1 at home this season.
Tuukka Rask had 23 saves through regulation and overtime, then stopped Nikolai Kulemin on the Maple Leafs' last chance to extend the shootout, which Boston led 2-1 on goals by Tyler Seguin and Bergeron.
Rask had been beaten by Kulemin on a breakaway in the second period, but stopped him this time, knocking the puck away with his blocker and preserving the win for Boston.
Toronto held Boston to just six shots in the third period, but Boston got a goal out of one of them when Bergeron scored at 10:36.
