Rookie defenseman Gary Suter scored the game-winning goal early and Calgary, dominating throughout, added two third-period goals to surprise the Oilers, 4-1, last night in Edmonton in the opener of their best-of-seven Smythe Division final series.
Game 2 is set for Sunday night, also in Edmonton.
Leading, 2-1, after two periods, the Flames got goals from Joe Mullen 40 seconds into the third and from Hakan Loob at 9:09 to put the game away.
The Flames would not yield the blue line or the slot area to the high-powered Oilers -- a tactic that kept Edmonton off balance.
Rookie goalie Mike Vernon, who has not lost to the Oilers in three games this season -- tying and winning in his two regular-season appearances -- was sharp in stopping 31 shots, way below par for the Oilers.
The only goal he allowed was to Glenn Anderson with 12 seconds left in the second period, in which Calgary outshot Edmonton, 11-6.
Wayne Gretzky sent his left winger a pass from behind the Calgary net and Anderson tipped it in behind Vernon.
*Blues 6, Maple Leafs 1: In St. Louis, Gino Cavallini and Ron Flockhart scored seven seconds apart early in the second period to lead the Blues over Toronto in the opener of their best-of-seven Norris Division final series.
Charlie Bourgeois scored twice in the closing 14 1/2 minutes to help St. Louis take a 1-0 lead in the series. Game 2 will be Sunday night on Blues ice.
Jim Barr and Greg Paslawski also scored to help St. Louis extend its mastery at home over Toronto to 13 games since February 1983.
Cavallini scored from close range at the two-minute mark of the second period after Maple Leafs goalie Ken Wregget tipped the puck off Mark Reeds' stick, and Flockhart scored unassisted seven seconds later to give St. Louis a 3-0 advantage.
Toronto answered with Wendell Clark's goal at 8:04 of the second period. But the Blues, with Bourgeois scoring twice in less than nine minutes, pulled away in the closing period.
