Mike Cammalleri scored three times in the second period and the Montreal Canadiens celebrated their 100th anniversary with a 5-1 win over the Boston Bruins on Friday night.

Cammalleri scored twice to put Montreal up 3-0 before completing his fourth career hat trick with the Canadiens' fifth goal late in the middle period, drawing a roar from the sold-out crowd of 21,273 that featured some of the team's former greats, including Jean Beliveau, Guy Lafleur and Patrick Roy.

Jaroslav Spacek and Glen Metropolit also scored for Montreal, which ended a four-game losing streak after a nostalgic pregame ceremony that included the surprise jersey retirements of two of the storied team's oldest living legends, Emile Bouchard and Elmer Lach.

Carey Price, who wore a special anniversary-themed mask, made 37 saves. His shutout bid was spoiled at 4:45 of the third period when Vladimir Sobotka scored on a redirection with the Canadiens up 5-0.

The Canadiens, who have won a record 24 Stanley Cups, were founded on Dec. 4, 1909.

Tim Thomas made 18 saves in two periods, allowing five goals while his name was chanted derisively by the Bell Centre crowd. Tuukka Rask replaced Thomas to begin the third and stopped five shots.

Spacek opened the scoring 8:30 in and Boston, which hadn't lost through regulation in seven games (6-0-1), was unable to tie it during a 5-on-3 advantage for a full 2 minutes after Spacek and Maxim Lapierre were both penalized for roughing 5:34 into the second.

The crowd, already charged up from the pregame ceremony, responded to the clutch penalty kill with a sustained cheer which only grew louder moments later when Cammalleri beat Thomas from the slot to put the Canadiens up 2-0.

Cammalleri added his second straight goal on an unassisted effort at 13:33 and Glen Metropolit increased the lead to 4-0 when he redirected Hal Gill's pass into the net at the right edge of the crease for his sixth goal at 16:07.

Cammalleri, who recorded his first Montreal hat trick in a 5-4 overtime win over the New York Rangers on Nov. 24, took Scott Gomez's pass and drove a one-timer past Thomas for his team-leading 15th goal.

A couple of dozen hats rained down onto the ice from the crowd _ along with a Bruins jersey _ and Cammalleri pumped his fist as he sat on the bench while TV images showed Canadiens greats applauding from their seats in luxury boxes.
