For better or worse, Tony Stewart vows to keep his competitive edge while racing against his wife

Stewart flashed the same kind of reaction time that made him a top contender in NHRA last year, just his third full-time season in drag racing. The three-time NASCAR champion and 1997 IndyCar champ won the NHRA’s regular-season title in the Top Fuel class while filling in for wife Leah Pruett at Tony Stewart Racing.
