Bruins, Thomas blank Penguins, Crosby

Matt Hunwick backhanded a rebound under the crossbar, then had to wait 77 seconds for a whistle so officials could consult a video replay and give Boston the goal. Mark Recchi had the 900th assist of his career on Daniel Paille's first goal with the Bruins, and Patrice Bergeron added a shorthanded empty-netter as Boston won back-to-back games for the first time this season.

"It's just one of those things where [Crosby's] in a rut right now," Recchi, a former teammate, said. "It won't be very long he'll be in it, I know that. He's a great player and when they break out, they can go the opposite way, and everything they touch turns to goals."

Pittsburgh has not scored in 149 minutes, 9 seconds, and has lost three straight games.
