Soon after high school he moved into road racing, winning the Super Vee title in 1981 and the Can-Am title in 1982. He was a key member of many notable teams throughout his career and made a name for himself while driving for Galles Racing, Doug Shierson Racing, Team Penske, and others.

In 2007 he was inducted into the Indianapolis Motor Speedway Hall of Fame and, shortly after in 2009, was inducted into the Motorsports Hall of Fame of America.
