Points leaders Mark Martin and Morgan Shepherd will start from the front row in today's Miller 400 at Michigan International Speedway because of rain that kept the NASCAR Winston Cup cars from qualifying.

Yesterday's nearly day-long rain in Brooklyn, Mich., lifted only long enough for the cars to get in a total of 30 minutes of late practice on the two-mile, high-banked oval.

For the second time this season -- the first was in Atlanta in March -- NASCAR had to use its rainout formula to fill the field. The top 30 spots were taken by the current leaders in car-owner points, and the rest of the lineup established on the basis of postmarks on entry blanks.

Martin leads Shepherd by 63 points in the Winston Cup standings. Another 10 points back is defending series champion Rusty Wallace. He will start third alongside Geoff Bodine.

Also starting in the top 10 will be Dale Earnhardt, Kyle Petty, Ken Schrader, defending champion Bill Elliott, Darrell Waltrip and Davey Allison. . . .

Danny Sullivan will start the 100th Indy-car race of his career from the pole in today's Budweiser-G.I. Joe's 200 in Portland, Ore. Sullivan's track-record lap of 122.129 mph in Friday's first round of qualifying held up, earning him his 16th Indy-car pole.

Michael Andretti's top speed Friday of 121.643 held up for the No. 2 spot on the starting grid for the $700,000 race.
