DALLAS -- Ben Bishop made 27 saves for the Dallas Stars in a 4-2 win against the St. Louis Blues in Game 4 of the Western Conference Second Round at American Airlines Center on Wednesday.
The best-of-7 series is tied 2-2. Game 5 is at St. Louis on Friday.
"It's a big response by our guys and a big win for these fans," Bishop said. "Desperation's a good word, but I think we were just playing the way we were supposed to play. Guys came in tonight and did the job."

Tyler Seguin, Alexander Radulov and Mats Zuccarello each had two assists for Dallas.
"(We've) been here before in the last series down 2-1, win Game 4 (against the Nashville Predators in first round)," Stars captain Jamie Benn said. "We've had a couple good Game 4s. Now got to go into St. Louis for a big Game 5.
"I think we had a much better effort tonight as a group. I know [Bishop] was solid in the net. When you play hard and play the right way, you get a good result, and we got that tonight."

Vladimir Tarasenko and Robert Thomas scored, Ryan O'Reilly had two assists and Jordan Binnington made 27 saves for the Blues, who had been 4-0 on the road in the Stanley Cup Playoffs.
"They played better than us when you look at the whole game. We had some good things at times, but our consistency wasn't there," O'Reilly said. "We didn't find our offensive structure until later on and it was too late. That happens, (there are) adjustments we have to make. We're disappointed. That wasn't the kind of game we wanted, but it's a best out of three now and we're confident we'll turn it around."
Stars coach Jim Montgomery, who frequently changed lines during the regular season, broke up his top line of Seguin-Benn-Radulov for the game. Seguin played on a line with Jason Dickinson and Zuccarello, and Roope Hintz joined the line with Benn and Radulov.
"What I think it comes down to is guys personally elevating their game," Dickinson said. "If it took shaking up the lines to get guys to do that, then it's a great move by the coach."
Tarasenko gave St. Louis a 1-0 lead at 5:02 of the first period with a wrist shot from the top of the right circle that went under Bishop's arm on the power play. Vince Dunn, who replaced Alex Pietrangelo on the first power-play unit, had the primary assist.
Dickinson tied it 1-1 at 11:23. After Zuccarello's shot from the high slot went wide, Seguin got the puck off the end boards and shot it back on net, where Dickinson got the rebound and scored with a backhand while falling across the crease.

Jason Spezza gave Dallas a 2-1 lead at 19:08, getting a loose puck at the top of the right circle and scoring with a slap shot on the power play.
"That was a tough one to give up," Blues coach Craig Berube said.
John Klingberg took a cross-ice pass from Seguin before scoring blocker side to give the Stars a 3-1 lead at 9:26 of the second period, and Hintz extended the lead to 4-1 at 17:28 when he took a cross-ice pass from Benn on a rush.

Binnington was assessed two minor penalties at the end of the second period, one for roughing Benn and one for slashing Bishop, but Spezza doesn't think the Stars have gotten inside his head.
"Nah. He's on a hot streak, and he's a guy that's played great," he said. "He's proven to be a really good goaltender. It's going to be a full reset next game, and I expect he'll be that way, too."
Thomas cut it to 4-2 at 13:44 of the third period, scoring short side from the left circle on Bishop, who had lost his stick after making a save on Pietrangelo.
