Stewart ashamed of confrontation with track owner

DAYTONA BEACH, Fla. (AP) - Tony Stewart says he's embarrassed
about his confrontation with a track owner in Australia.
      The two-time NASCAR champion was questioned by police at Sydney
Speedway last week. He says the dispute was over track conditions
that Stewart believed endangered drivers.
      Stewart did not identify the other person in the dispute, but
several Australian racing websites reported he fought with speedway
co-owner Brett Morris.
      Stewart is at Daytona International Speedway for three days of
testing leading to next month's season-opening race.
