Dale Earnhardt passed Alan Kulwicki on the last lap to win the Summer 500 NASCAR race at Pocono International Raceway in Long Pond, Pa., yesterday.

The lead changed several times on the last lap, and the two appeared to collide before Earnhardt moved inside of Kulwicki and won by two car lengths. Buddy Baker was third, but wasn't a factor at the finish of the 200-lap race.

It appeared Earnhardt would outrun the field after an oil leak eliminated Rusty Wallace with about 30 laps left.

Kulwicki closed on Earnhardt when the ninth caution flag came out with only nine laps left.

It was Earnhardt's ninth victory of the season, but the first of his career at the 2 1/2-mile tri-oval. He leads the Winston Cup standings.

Tim Richmond, who had won three straight at Pocono, had set a track record in winning the pole. But he dropped out after about 300 miles because of engine problems . . .

Emerson Fittipaldi survived a last-lap collision with second-place Danny Sullivan to win the Molson-Indy in Toronto.

Sullivan got past Bobby Rahal to take second 11 laps from the end, but Fittipaldi, driving a Chevrolet-powered March, led Sullivan by 3.23 seconds going into the last lap. Fittipaldi then came upon the slower-moving cars of Michael Andretti and Scott Goodyear. Fittipaldi and Sullivan got past them, then Sullivan tried to go ahead on the inside heading into a turn.

Fittipaldi pinched Sullivan toward the concrete barrier on the inside of the turn and Sullivan spun, stopping momentarily. Fittibaldi spun sideways but straightened himself out, accelerated and beat Sullivan to the finish line by 8.35 seconds . . .

Elliott Forbes-Robinson of Denver, N.C., took the lead on the last lap and won the Pepsi Grand Prix Trans-Am feature in Brainerd, Minn. Paul Newman lost an early lead to place fifth . . .

William Vermeer, 33, of Groveport, Ohio, was killed during the Indy Grand Prix at Indianapolis Raceway Park when his Formula Continental hit a guardrail.
