The Stanley Cup playoffs continue on Wednesday with four major games. Two of those series could come to an end while the other two will face pivotal Game 4 matchups that could shift the series one way or another.

Montreal Canadiens vs. Ottawa Senators - Game 4 (Montreal Leads 3-0)

The magical run of the Ottawa Senators to get into the postseason seems to have come to an end. The team plays Game 4 in front of its home fans looking for a win that could launch an improbably comeback.

Only four NHL teams have managed the feat including the 2014 Los Angeles Kings, the 2010 Philadelphia Flyers, the 1975 New York Islanders and the 1942 Toronto Maple Leafs. Could Ottawa be No. 6?

The odds are against them, especially if they cannot figure out their goaltending situation.

Andrew Hammond, who had a sterling .941 save percentage in his 24 games for Ottawa has regressed somewhat to an average .914. Meanwhile, his replacement in Game 3, Craig Anderson, managed to only concede two goals in the 2-1 overtime defeat.

But the reality of the situation is that Ottawa needs to possess the puck. All indications pointed toward the Sens being the better puck possession side in the matchup, but Montreal has outshot the Senators in each of the three games; what's more, the Canadiens have managed 39 shots or more in every single game of this series. If Ottawa does not regain possession, this is over in four.

Prediction: Montreal sweeps.

NY Rangers vs. Pittsburgh Penguins - Game 4 (Rangers Lead 2-1)

The Rangers entered this series as the heavy favorites, but the series actually looks a lot closer than anticipated with three one-goal games. The common theme of the series has been the Penguins' sloppy starts to games. The team has been outshot 23-17 through the opening 20 minutes and 70-47 through the opening 40 minutes of play. The team had also been outshot in the third in Games 1 and 2, but was far superior in Game 3.

The Penguins were a better possession team in the regular season (they ranked 13th in shot attempts for while the Rangers ranked 17th), but the Rangers have clearly looked like the more successful team in holding the puck.

Goaltending is not an issue for Pittsburgh, but it needs offense from Evgeni Malkin, who has no points and just four shots in this series. Sidney Crosby has been solid, but he cannot do it alone and needs his partner to step up his game.

Prediction: Pittsburgh wins Game 4. Malkin stars.

St. Louis Blues vs. Minnesota Wild - Game 4 (Minnesota Leads 2-1)

We see it every year. The Blues are primed to be a top contender but they flop at the first hurdle in the playoffs. And now they are facing a tough predicament in Game 4.

First of all, the team has not quite figured out Devan Dubnyk, who has stopped .922 percent of the shots he's faced and has allowed under two goals per game; his 1.68 goals against average is third in the entire playoffs and second for goalies with at least one start.

Neither team is a top tier puck possessor but the Wild have been the superior team with the puck, outshooting the Blues in two of the three contests and limiting St. Louis to a measly 17 shots in Game 3. St. Louis had 27 shots in Game 2, which is well above the average the team managed throughout the regular season.

The problem is that if the regular season is any indication, St. Louis is likely to produce performances similar to those in Game one and three (the team averaged just 21.7 shots per game in the regular season) while Minnesota was the second best team in the league in suppressing them.

Prediction: More Dubnyk magic and Blues choking. Minnesota takes Game four.

Winnipeg Jets vs. Anaheim Ducks - Game 4 (Anaheim Leads 3-0)

Will we see two sweeps in one day? The Jets have played well against the Ducks, but have found themselves victims to late goals in each of the games. In Game 1, it was a goal with under seven minutes left that gave Anaheim the win. In Game 2, it was a crushing tally with 19 seconds remaining. And in Game 3, the Jets saw a goal with under three minutes left tie the game and force overtime.

Another common theme in these games? The Jets led by one goal in each game heading into the third but wound up blowing those leads on their way to losses.

And maybe it is time to look at the goaltending as Ondrej Pavelec has a putrid save percentage of .893 through three games. He hasn't been horrid, but he hardly looks like the kind of goalie that could steal a game to get his team back into the series.

Prediction: Winnipeg wins its first franchise playoff game (this is technically the same franchise as the Atlanta Thrashers which never won a playoff game) and pushes the series to a fifth game.
