WEST ALLIS, Wis. ? Scott Dixon came to the Milwaukee Mile this week with the IndyCar Series points lead and more than a little trepidation about facing one of American open-wheel racing’s oldest oval tracks.

The 2003 series champion, who has not had much success here, has moved to the top of the standings after five races by virtue of consistency. But Dixon has yet to win a race this season, finishing second three times, including last Sunday’s Indianapolis 500, and fourth twice.

Heading into today’s ABC Supply/A.J. Foyt 225 at the suburban Milwaukee track, Dixon holds a one-point lead over Target Chip Ganassi Racing teammate Dan Wheldon, winner of two races already this season, and is three points ahead of Indy winner Dario Franchitti.

Helio Castroneves and former series champions Tony Kanaan and Sam Hornish Jr., are lurking within 33 points of Dixon with 12 races remaining in 2007.

“I think you want consistency,” Dixon said. “But, at this stage in the season, you want to go out for race wins. Those three second-place finishes, that’s not nearly good enough for me.

“I think some of them we could have turned into wins. We definitely need to do that. We’ll be as aggressive as we need to be.”
