The Ottawa Senators will bring a new level of confidence when they face off against the Pittsburgh Penguins in Game 4 Wednesday night, while the New York Rangers find themselves on the brink of playoff extinction. All this and more in Tuesday night’s Stanley Cup stories.

1. The Pittsburgh Penguins have one of the most explosive offences in hockey. The Ottawa Senators realize this but aren’t scared off by their high-octane opponents, particularly when Craig Anderson is manning the net. A huge comeback win to narrow the Eastern Conference semifinal series to 2-1 will do that to a team.  And with the teams set for Game 4 Wednesday (CBC, CBCSports, 7 p.m. ET), players like Senators’ hard-working defenceman Andre Benoit become even more vital to a team like the Senators, writes CBCSports.ca senior hockey writer Tim Wharnsby.

2. Despite Henrik Lundqvist’s best efforts to resemble a vintage Patrick Roy, he couldn’t overcome a listless New Rangers offence as the Boston Bruins took a commanding 3-0 series lead following a 2-1 win at Madison Square Garden. The Rangers led 1-0 after two periods, but goals by Johnny Boychuk (3:10) and Daniel Paille (16:29) in the third period has New York on the brink of elimination. The Bruins’ winning formula has been obvious: their depth is destroying the Rangers.

3. The San Jose Sharks won’t go away. They drove that point home again in Game 4, holding off the defending Stanley Cup champion Los Angeles Kings 2-1 to even their Western Conference semifinal series at 2-2. The Sharks have to be thrilled with the play of often-maligned centre Joe Thornton, who assisted on Brent Burns’s opening goal in the first period, bringing his playoff total to nine. San Jose will now try to break a string of wins by the home teams on Thursday (10:30 p.m. ET).
