Marty St. Louis scored the Lightning's only two goals on power plays Monday, beating Pittsburgh's Marc-Andre Fleury with a backhander from the right edge of the crease in the first and with a wrist shot from the same spot in the third.

A couple of weeks ago, St. Louis probably wouldn't have scored either goal because a couple of weeks ago, St. Louis probably wouldn't have been in a position to score either goal.

St. Louis' role on the power play has changed in recent weeks, largely as a result of the acquisition of D Eric Brewer, who came to the Lightning in a trade-deadline deal with the Blues.

With Brewer on board, Lightning coach Guy Boucher has taken advantage of the veteran backliner's ability to play the point and moved St. Louis from the point to a position where he can make better use of his skills.

"We never really wanted Marty on the point in the first place, but we put him there because we didn't think anyone else could do the job," Boucher said. "All along I really wanted Marty where he is now."

Where St. Louis is now is often hard for opponents to gauge. His new role allows him to be down low near the net the way he was for his two goals Monday, along the boards, in the slot or — if Brewer is off the ice — at the point.

"The new arrangement relieves Marty of having to be on the point and having to manage everything and — if we do get caught — having to be the guy defending, which, with his size, is never really a good thing," Boucher said.

"I mean, I really didn't want to put Brewer there either because he was getting so much ice time already, but he gives us reliability there if we get caught, and that's something that was a bit of a problem for us."

Tampa Bay lost 3-2 on Monday and trails the Penguins 2-1 in their best-of-seven series.
