After years as a star in Midwestern dirt Late Model racing, Phillips switched to asphalt tracks in 1989 when two tracks near him: I-44 Speedway, Lebanon MO and Speedway USA, Bolivar MO were paved. That year, driving an asphalt Late Model that he owned, Phillips won 23 of the 27 NASCAR-sanctioned races that he entered, and won the track championship at Bolivar Speedway in Missouri. In 1990, Phillips added
James Ince (later a winning
Winston Cup crew chief) to his team, and won 32 races in 40 starts in 1991 at race tracks in Kansas and Missouri. The team's success continued in 1992 at the same race tracks, winning 38 times in 40 starts despite a trailer fire en route to the only double-feature event on their schedule. The team had more than 70 wins for the season including some late season dirt races. In 1995, Phillips once again won 32 out of 40 races, winning the national championship over
Greg Biffle by a tiebreaker. In his final national championship season, 1996, Phillips earned 14 wins in 20 starts. Phillips was diagnosed with lung cancer in 2000, but continued to race until the first race of the 2001 season. With his energy fading, he retired rather than race without confidence in being ready to win. ==Honors==
