TAMPA, Fla. -- Tim Thomas made 31 saves for his first playoff shutout this season and second overall, rookie Tyler Seguin scored his fourth goal in the last three games and the Boston Bruins beat the Tampa Bay Lightning 2-0 in Game 3 of the Eastern Conference finals Thursday night.

Thomas, the favorite to win the Vezina Trophy as the top regular-season goalie, gave up nine goals in the first two games of the series that the Bruins lead 2-1.

Seguin made it 2-0 from in-close at 8:12 of the third as the puck trickled between the legs of Lightning goalie Dwayne Roloson and into the net. After sitting out the Bruins' first two playoff rounds, the 19-year-old Seguin was inserted into the lineup to replace an injured Patrice Bergeron in Game 1 and has seven points overall. David Krejci also scored for the Bruins.

Game 4 is Saturday in Tampa.
