Weiss’ score pushed the Red Wings ahead 2-1 midway into the second period. Johan Franzen fired a pass from the left corner to Weiss alone in front and he beat Rask with a wrister inside the left post.
Detroit then made it 3-1 on Cleary’s goal 2:20 later when he slipped a shot by Rask inside the right post after collecting Alfredsson’s from the side of the net.
The Red Wings jumped ahead 1-0 when Zetterberg took a feed from Pavel Datsyuk midway into the first period. Datsyuk gathered the puck near center ice after Patrice Bergeron mishandled it, broke in down the middle, shifted around Boston defenseman Zdeno Chara and sent a backhand pass by two other Bruins perfectly to Zetterberg, who redirected it past Rask from the bottom of the left faceoff circle.
Johnny Boychuk’s shot from the right point ricocheted off Eriksson’s knee and by Gustavsson to tie the game at 14:12 of the first.
