Marc-Andre Fleury made 17 saves for Pittsburgh's first shutout of the season and the Penguins won 3-0 as the Bruins got little spark from their retaliation against Matt Cooke less than 2 minutes into the game Thursday night. Shawn Thornton squared off with Cooke 5 seconds after the Penguin came on for his first shift. The anticipation of a fight had built since March 7, when Bruins center Marc Savard was sidelined indefinitely after Cooke?s hit caused a Grade 2 concussion in Pittsburgh.
