The St. Louis Blues rolled to a 6-1 win against the Dallas Stars on Tuesday to take a 2-1 lead in this Western Conference Semifinals series. I like the Blues in tonight's contest as well which would see them travel to Dallas for Game 5 with a chance to close out the series.

Here are my keys to the game:

1. Special Teams - St. Louis is 4-for-14 on the power play over three games against Dallas here in the playoffs while successfully killing off each of the Stars 11 opportunities. The Stars have mustered only a total of four power play goals through their nine games in this season's playoffs.

2. Previous Meetings - The Blues have won eight of the past 10 meetings between the two teams and four straight home at Scottrade Center. The Blues' captain David Backes has three goals and an assist so far in the playoff series.

3. X-Factor - The Stars will once again be without Tyler Seguin, and the Stars have struggled to solve Brian Elliott without Segs with just six goals through the first three games.

Selection: This is a play on the St. Louis Blues (8*)
