After the Blues scored two goals in the first 32 seconds of the second period for a 3-1 lead, Tyler Seguin won the faceoff. He passed to Benn for a goal just six seconds later.

Benn had two goals and an assist, and Seguin a goal and two assists.
The Stars' Antoine Roussel added a second-period goal.
Dallas' Patrick Eaves appeared to score at 6:15 of the first period. However, a referee ruled that Jason Spezza interfered with Elliott, and disallowed it.
St. Louis took a 1-0 lead at 17:49 of the first, when Berglund deflected Michalek's shot from the right point into the upper left corner.
