Pittsburgh Penguins at Columbus Blue Jackets – 7:00 p.m. ET

Penguins superstars Sidney Crosby and Evgeni Malkin, as well as Chris Kunitz, James Neal and Kris Letang, have yet to score a goal in the first three games.

''Obviously, Sid and Gino [Malkin] and Kuni and James Neal are going to get a lot of the attention, a lot of the tougher matchups,'' said forward Lee Stempniak, who had the tying goal in Game 3, part of a three-goal two minutes 13 seconds in the third period. ''It sort of comes down to the secondary scoring and the other players who can make a difference in the series.''

Crosby hasn't scored a goal in his last seven playoff games, Malkin in his last six.

One of the reasons Crosby has been limited to four assists is hard-nosed Columbus forward Brandon Dubinsky. He's been stellar in not only helping to put the clamps on Crosby, who had an NHL-best 104 points during the regular season, but also adding four assists of his own.

There's no question he has been the emotional leader for the upstart Blue Jackets, making their first playoff appearance in five years and only the second in the franchise's 13 seasons.

''Duby relishes the big moments,'' said teammate Mark Letestu. ''His game is built for the playoffs. You can see at any moment that he's head-first into it.''

St. Louis Blues at Chicago Blackhawks – 9:30 p.m. ET

The Blues face the Blackhawks in Game 4 of their opening round series at Chicago on Wednesday night.

The Blues lost 2-0 in Game 3, but still lead the series 2-1.

But the Blues' series against the defending Stanley Cup champions seems to be unfolding as it did last season when they took a 2-0 lead against Los Angeles and then dropped the next four games.

''Within our walls, I don't think anyone is even thinking about last year,'' defenceman Barret Jackman said. ''The media comes in and you get all the comparisons.

''But really it's about what we're doing now. We're playing good hockey. We're playing against a team that is very hungry and has a lot of good experience.''

The Blues were better than Blackhawks for most of Monday's game. St. Louis coach Ken Hitchcock was almost beaming after the game when said his team had delivered it best effort so far in the series.

''I said last night we played good, but not good enough,'' Hitchcock said on Tuesday. ''I thought we were 80 percent in and if we're going to beat them tomorrow or win, we're going to have to make stronger commitment in our game. Click here to watch the game live.
