Martinsville, Va. — Rain forced the postponement of the NASCAR Cup Series race at Martinsville Speedway after just 42 laps Saturday night, setting up a doubleheader Sunday.

The day will start at noon with the completion of an Xfinity Series race that was suspended after 91 laps Friday night. That race has 159 laps to complete, and the Cup completion will begin at 4 p.m. in conditions that weather forecasts suggest will be sunny and in the mid-70s.

Denny Hamlin passed pole-sitter Joey Logano just four laps into the race and led the rest of the way until light drizzle intensified and the drivers were told to come down pit road for a red flag delay. Conditions on the track were good, but pit road was very wet.

Climbing from his car, Martin Truex Jr. joked that visibility wasn't much of a problem.

“You could see a lot more than we could at Bristol two weeks ago,” Truex said, referring to the dust that was so challenging when the series ran on dirt at Bristol Motor Speedway.

Weather forecasts all day called for rain around race time, and monsoon-like conditions arrived around the 7:30 p.m. scheduled start time. Jet dryers circled the track for more than an hour, then made two passes on pit road trying to limit the puddling.

The race got underway at 9:25 p.m.
