Calgary, Alberta ? The Tampa Bay Lightning didn’t ask goalie Nikolai Khabibulin for much in the biggest game in their history, only perfection. He delivered it, too, by all but saving their season.

Khabibulin again was at his best when the Lightning are in trouble, staying undefeated following a loss in carrying Tampa Bay to a series-tying 1-0 victory over the Calgary Flames in Game 4 of the Stanley Cup finals Monday night.

Brad Richards scored during a two-man advantage in the opening three minutes, his fourth game-winning goal following a Lightning loss. Khabibulin made the goal stand up by making 29 saves in his fifth playoff shutout this spring.

“I have to stay focused no matter what. It was nice that we got the first goal,” Khabibulin said. “We didn’t get any more, but that was enough to win.”

Barely enough, as the Flames pressured all night with 10 more shots than in any other game in the series.

“That’s good goaltending,” Calgary star Jarome Iginla said. “We had some chances, but, unfortunately, we didn’t make the best of them.”

Richards’ 10th goal of the postseason was his seventh game-winner, breaking the record he previously shared with Joe Sakic (1996) and Joe Nieuwendyk (1999). The Lightning are 30-0-2 overall and 8-0 in the playoffs when Richards scores.

The Lightning would have been in desperate straits down 3-1, as only the Toronto Maple Leafs in 1942 overcame that disadvantage in the final. It didn’t help that Tampa Bay was without two key regulars, Ruslan Fedotenko and Pavel Kubina, who were injured in Calgary’s 3-0 victory Saturday.

“We found a way to get it done, and that’s the most important thing,” coach John Tortorella said. “Ugly as hell, but we found a way.”
