Joel Otto scored at 7:32 of the final period last night, lifting Calgary to a 3-2 triumph over the stunned Edmonton Oilers and giving the Flames a 2-1 lead in their best-of-seven Smythe Division final series.

Calgary outshot Edmonton, the defending Stanley Cup champions, by 38 to 19 -- 16 to four in the second and 14 to five in the third period -- before 16,762 cheering spectators at Calgary's Olympic Saddledome. Only some fantastic goaltending by Grant Fuhr kept the Flames from a much bigger win.

The Flames lost a 2-1 lead in the third period when Glenn Anderson's backhand shot beat rookie goalie Mike Vernon. Anderson took a pass from Wayne Gretzky and waited for Vernon to commit himself by dropping to the ice.

In the first, Paul Reinhart scored for Calgary, then Wayne Gretzky countered for Edmonton, both on power plays. Calgary went ahead midway through the second on Colin Patterson's goal.

Maple Leafs 5, Blues 2: Wendel Clark, Rick Vaive and Russ Courtnall scored within one minute 42 seconds late in the third period to give Toronto the victory over St. Louis and a 2-1 advantage in their Norris Division final series.

Clark, at top speed, took a rink-wide pass from Courtnall, circled the St. Louis net and reached from behind the goal line to tuck the puck behind goaltender Rick Wamsley at 13:49 of the third period for his fifth goal of the playoffs.

From 20 feet, Vaive whipped his second goal of the game through Wamsley's legs at 15:18 and Courtnall connected on a feed from Clark 13 seconds later before the sellout crowd of 16,382.

The Maple Leafs had tied 40 seconds into the third period on center Tom Fergus' power-play goal.
