The Bruins it is presumed will get better when all their new parts get comfortable in their Black ‘n’ Gold skin. And with the Detroit Red Wings coming to town Saturday night they’d better improve quickly.

But in their season opener at the Garden tonight they were good enough to produce a crowd-pleasing 3-1 win over the Tampa Bay Lightning.

Chris Kelly scored on a penalty shot while Milan Lucic and Patrice Bergeron each added goals Shawn Thornton and Jarome Iginla dropped the gloves and Tuukka Rask was solid in the victory.

The B’s took a 2-1 lead into the third period where they faced their second lengthy 5-on-3 of the game. With both Thornton and Zdeno Chara in the box the B’s hung on until Ryan Malone was called for interference on Johnny Boychuk with 26 seconds left in the Tampa two-man advantage.

And on the 4-on-3 situation the B’s scored their second shorthanded goal of the game. After a nice Adam McQuaid defensive play Patrice Bergeron broke out on a -on-1 with Torey Krug. Bergeron elected to keep the the puck drifted into the slot and fired a shot that broke though Anders Lindback

The Bruins entered their 90th season on a rather tepid run of season openers. In their last 13 debuts they owned a 3-8-2 record.

And they didn’t play all that well in the first period unless they were on the penalty kill. That’s where they took a 1-0 lead.

With Reilly Smith in the box for hooking the B’s created a couple of shorthanded chances. First Loui Eriksson had a good shot on Anders Lindback and then Brad Marchand created an opportunity for Bergeron that Lindback stopped.

But the best chance came from Chris Kelly. In the neutral zone he picked off a Mark Barberio drop pass intended for Valtteri Filppula and took off on a breakaway. Barberio hooked him from behind and Kelly was awarded a penalty shot.

Kelly struggled offensively all last season with one of the burning images of the Stanley Cup final against Chicago being him missing an open net in Game 4. But on the penalty shot he came straight down the middle made a great shimmy move to freeze Lindback and tucked it home for a 1-0 lead at 11:39.

That’s the way it would stay for the period though the Lightning outshot the B’s 15-6 and had a great chance to tie it with a lengthy 5-on-3 at the end of the period.
