After 60 scoreless minutes, Brad Marchand needed just seconds to lift Boston to the win.
Marchand scored 10 seconds into overtime, Jonas Gustavsson made 42 saves and the Bruins beat the host Tampa Bay Lightning 1-0 on Tuesday night in a matchup of Atlantic Division leaders.
Patrice Bergeron sent a pass from the right wing through the slot that Marchand redirected past Ben Bishop for his 34th goal.
“It was big,” Marchand said. “We’re battling for position. We’re definitely happy with the outcome. It’s showing we’re learning how to win these games.
