When Jeff Gordon won at Sears Point last week, he joined Mark Martin in having won at 16 of the 20 tracks now in use on the Winston Cup circuit. Martin could move back ahead by winning this weekend at Daytona. Here are the tracks where Gordon and Martin have not yet won: Gordon: Las Vegas, Texas, Phoenix and Michigan. Martin: Daytona, Indianapolis, New Hampshire and Pocono.(That’s Racin’ – Random Thoughts, David Poole)(7-2-98)
