Dale Earnhardt continued his dominance at Darlington Raceway yesterday, earning his second consecutive victory in the Southern 500.

Earnhardt, winner of six of the last 10 races at the South Carolina track, took the lead for good on Lap 314 following pit stops under green by the leaders. After the pit stops, the three-time Winston Cup points champion had a 4.1-second lead and was never seriously threatened over the final 54 laps en route to his seventh victory of the year. He averaged 123.141 mph in earning a 4.08-second victory over Ernie Irvan.

Earnhardt earned $205,350, including a $100,000 bonus that goes to a driver who wins two of the circuit's four major races; he also won the Winston 500. Earnhardt has won more money than any driver in motorsports history, nearly $11.2 million.

Alan Kulwicki finished third, followed by Bill Elliott and Harry Gant. . . .

Al Unser Jr. took a record-setting fourth straight victory by claiming the inaugural Molson Indy-Vancouver, which was marred by an accident that injured six course workers.

The series point leader dominated the second half of the 97-lap, 165.29-mile event, beating Danny Sullivan by 10 seconds.

One track worker was hospitalized with what race officials called "significant head injuries" and two others were treated for less serious injuries after they were struck by Willy T. Ribbs's car. Three others were treated at the track and released.

The workers were push-starting the car driven by Canadian Ross Bentley at a slow corner on the new track near downtown Vancouver on Lap 17. Bentley's engine restarted and, as he pulled away, several of the workers darted toward the wall and directly onto the path of Ribbs's car.

Unser's victory, the 15th of his career and sixth in 12 races this season, made the 28-year-old the first driver in CART's 12-year history to win more than three in a row. He led 58 laps and averaged 77.350 mph.

Mario Andretti was third, followed by Rick Mears and John Andretti.
