The New York Rangers and Montreal Canadiens clinched the final two playoff berths in the Eastern Conference Thursday, but the final two spots in the West are still up for grabs as the regular season wraps up this weekend.

Three teams, all with 88 team points, compete for those two West berths. When the Nashville Predators secured a must-win over the Detroit Red Wings in a Thursday night shootout, they joined the Anaheim Ducks and St. Louis Blues as the only teams still legitimately in the West race.

The Predators, who had lost three of their last four games prior to their trip to Detroit, overcame a two-goal deficit in the final seven minutes of regulation to tie the score at 3-3. Jason Arnott ignited the comeback with his 31st goal of the season, and with the Preds on a power play and their goalie on the bench, J.P. Dumont knotted the score on a goal-mouth scramble with exactly a minute remaining. Arnott’s tally in the fourth round of the shootout saved Nashville’s season.

Odds still work against the Predators, as they close out the regular season in Minnesota Friday night while both the Ducks and Blues have two games remaining.

“This is the biggest game of the year,” Arnott said after netting the game-winner against Chris Osgood. “Tomorrow night will be the biggest game of the year.”

It’s hard to argue with Nashville’s leading goal scorer. The Predators face a Minnesota team that is still officially in the playoff hunt with 85 points and must win its final two contests to stay alive. The Wild are 22-11-7 at home.

Meanwhile, both the Ducks and Blues host division rivals Friday night. The Ducks face Dallas, against whom they are 2-2-1 this season but have lost twice on their home ice. The Blues square off with Columbus, and they are 4-1-0 against the West’s sixth seed. Anaheim finishes in Phoenix Saturday, and St. Louis travels to Colorado to play the team with the West’s worst record on Sunday afternoon.

The Predators needs plenty of help to advance. If they were to pull it off and the Blues were to earn the other postseason berth, all five teams in the Central Division would be playoff-bound. If the Ducks were vanquished, the San Jose Sharks, owners of the Western Conference’s best record, would be the only Pacific Division club vying for the Stanley Cup.
