Alexander Radulov scored at 16:05 of overtime to give the Dallas Stars a 5-4 win against the Calgary Flames in Game 4 of the Western Conference First Round at Rogers Place in Edmonton on Sunday.
Radulov's goal tied the best-of-7 series for Dallas, the No. 3 seed in the West.
Game 5 is in Edmonton, the West hub city, on Tuesday (5:30 p.m. ET; NBCSN, SN, CBC).
"It was a good forecheck from the start and then all the guys on the ice, we realized they had one guy without a stick and we tried to use it to our advantage," Radulov said. "The guys up top did a good job. They were putting pucks on net and we were trying to recover it, those pucks. Get to the slot area and eventually we got that goal. It's good to bounce back."

Joe Pavelski scored his first Stanley Cup Playoff hat trick, getting the tying goal with 12 seconds left in the third period for Dallas. John Klingberg had three assists, including his shot Radulov tipped on the game-winner, and Anton Khudobin made 36 saves for his first Stanley Cup Playoffs win.
"We're in the moment," Pavelski said. "It's a big game. We're trying to win. There's some different things that happened, us giving up a shorthanded goal again and things like that. It doesn't really matter. You stay in the moment. You understand you're going to get another chance to tie this game up and find a way to win.
"That's what this group did today. It was an attitude that we were going to find a way to win. It took a while to get that game tied, but there was never a sense that we weren't going to win once we got to overtime. A couple big plays there and we're on the right side tonight."

Cam Talbot made 57 saves, and Sam Bennett had two goals and an assist for the Flames, the No. 6 seed. Talbot's saves are the second-most in a game by a Flames goalie (Rejean Lemelin, 61 saves, April 11, 1981 in a 5-4 two-OT win against the Chicago Blackhawks, Preliminary Round).
"It was a back-and-forth game in overtime," Calgary captain Mark Giordano said. "We had some looks. Unfortunately, we had a broken stick and it gave them possession and they capitalized. It was a good game. We've got to take what we have to out of it and move on. It's 2-2. Best-of-3 now. It's a tight series. It's been really tight all series. It'll continue to be that way, I'm sure."
Pavelski tied the game 4-4 on a rebound at 19:48 of the third period.
The 36-year-old is the oldest player to score a hat trick in the playoffs since Brett Hull, who was 37 when he did so for the Detroit Red Wings against the Vancouver Canucks in Game 6 of the Western Conference Quarterfinals on April 27, 2002.
It was the fourth playoff hat trick in Stars/Minnesota North Stars history (Dino Ciccarelli twice, Steve Payne, Bob Brooke), and the first since the team relocated to Dallas in 1993-94.
Pavelski's third goal came after Jason Dickinson looked to have scored at 17:31, but the Flames successfully challenged for goalie interference by Corey Perry on Talbot.
"I understand there's still time left to go do it again," Pavelski said. "There's really not another attitude you can take to it. It's a tough break. I think one of the things that I've learned in my career is adversity is going to hit at some point in the playoffs. It always does. If you're in the right mindset to handle it and give yourself an opportunity to produce something after it."
Pavelski scored on the power play at 18:11 of the first period to put Dallas up 1-0. He was playing his 138th Stanley Cup Playoff game.
Gaudreau tied it 1-1 with a power-play goal at 1:54 of the second period, and Pavelski gave the Stars a 2-1 lead at 3:14 with a shot by Talbot's blocker off the rush.
"[Pavelski] is another veteran voice, a leader," Dickinson said. "Guys can lean on him. He's been around for a while. He knows the ins and outs. These are the games he lives for. He elevates for these kinds of moments. You hear him on the bench. He wants to be out there. He wants to make the big play and have a big impact."

Bennett scored 43 seconds later with a slap shot on the power play to make it 2-2.
Bennett made it 3-2 when he scored on a rebound off Milan Lucic's shot at 14:50, and Denis Gurianov one-timed a pass from Miro Heiskanen by Talbot on the power play to tie it 3-3 with 37 seconds remaining in the second.
Rieder scored shorthanded to put Calgary up 4-3 at 3:11 of the third period when he redirected a centering pass from Derek Ryan by Khudobin's blocker. Rieder is the only player in Flames history to score three shorthanded goals in a single postseason.
"It's just a short memory," Bennett said. "We have to take what we can and move on. It's 2-2. It's two good teams going at it. This is playoffs, and it's exciting hockey. We're not going to dwell on it. Obviously, we would've liked to win that and go up 3-1, but 2-2, we're in a perfectly good situation here."
