After missing the playoffs last year, the Blues opened this season at SportsInteraction at 50/1 to win the Stanley Cup. Now they're the 4/1 favorite.

It's the same story at the LVH SuperBook, where the Blues opened at 30/1 and are now the 7/2 favorite.

St. Louis had not won a playoff series in a decade before ousting San Jose on Saturday night.

At SportsInteraction on Monday, St. Louis was followed closely by Philadelphia and Nashville (+450 each), Los Angeles (+550), Boston (+650) and the Rangers (+950). Phoenix and Ottawa were +1400 apiece, with Washington and Chicago priced at +1900 each.

Florida (+2200) and New Jersey (+2500) were the biggest long shots.

There's a different hierarcy at MGM Mirage's sportsbooks in Vegas. MGM Mirage had the Flyers at +250, the Blues at +300 and the Kings at +400.

"That's obviously a bit low for the Kings, but before the season started we took a lot of money on the Kings and we've been trying to dig ourselves out of a hole with them all year," sportsbook manager Jeff Stoneback said. "As it is right now, we're just a small winner with the Kings [winning the Cup]."

Stoneback said Cup futures are drawing good, balanced action.

"It's spread all over," he said. "Nobody has jumped out on one team."

The second-seeded Blues, who face the eighth-seeded Kings in the second round, were +200 to win the West at SportsInteraction, followed by Nashville (+220) and L.A. (+250). Nashville knocked off Detroit and awaits the winner of Phoenix-Chicago.

The Flyers, who upset the high-powered Penguins in the first round, were favored in the East at +250. The Bruins were close behind at +325, followed by the Rangers at +450.

Boston forced Game 7 with Washington by winning 4-3 in overtime Sunday. The Rangers trail Ottawa 3-2 heading into Monday night's Game 6 in Ottawa.

St. Louis-L.A., the only second-round matchup set thus far, won't feature a lot of offense. The Blues allowed an NHL-low 155 goals in the regular season, and the Kings were second with 170 allowed. St. Louis goalie Brian Elliott led the league with a 1.56 goals-against average. L.A.'s Jonathan Quick finished second with a 1.95 GAA.

The teams played four times in the regular season, and twice the games ended 1-0. St. Louis will be a slight favorite in the series despite losing three of four to L.A. in the regular season.

The Kings just stifled the top-seeded Canucks in Vancouver in Game 5, rallying for a 2-1 OT win to take the series.
