Danny Sulliva's first mistake gave Al Unser Jr. the lead and his second mistake gave Unser Jr. a victory.

Unser Jr. captured his second win of the year Sunday, as one bad choice and one driver penalty cost pole-sitter Danny Sullivan a chance at victory in the $700,000 Molson Indy CART event.

Unser Jr. and Sullivan were clearly the best cars on the day, pulling away in tandem from the start.

When the yellow flag appeared on lap 16, Sullivan chose the wrong way around a slower car and lost the lead on the dash back to the finish line. Just two seconds behind Unser Jr. with 30 laps to go, Sullivan committed an infraction exiting the pits. The resulting penalty gave Unser Jr. his 12-second margin of victory.

"I'm not saying I could have beat Al, but it would have been a close race right to the end," Sullivan said.

While leaving the pits, Sullivan crossed a line separating the pit exit from the raceway, resulting in a stop and go penalty. On a stop and go penalty, cars are required to pit again and come to a complete stop.

"I didn't think I went over," Sullivan said. "They say they saw it. They just took away a great day of racing.

"It's a pretty good rule. You don't want people shooting out of the pits right out into the race. But it's amazing how they see all your stuff and miss so much," he added.

Sullivan was one of many drivers to be penalized for that infraction. Bobby Rahal, Emerson Fittipaldi, Raul Boesel and Teo Fabi also were caught.

Sullivan was upset by the way he lost the lead on lap 16. A crash by Kevin Cogan brought out the yellow flag, and Unser Jr. beat Sullivan back to the finish line.

"A.J. (Foyt) blocked me," Sullivan said. "I thought he was on little Al's payroll."

AT Elkhart Lake, Wis., a timely yellow light helped Geoff Brabham rebound from an early setback as he won the Miller High Life 500-kilometer Camel GTP feature race Sunday at Road America.

At Englishtown, N.J., top fuel racer Joe Amato took over the Winston Series point lead and Don Prudhomme won his second Funny Car event in a row Sunday in the National Hot Rod Association Summernationals at Old English Township Raceway Park.
