WATKINS GLEN, N.Y. — The NASCAR Sprint Cup race at Watkins Glen International has been postponed because of rain and rescheduled for tomorrow.

A thunderstorm hit the track about 2 p.m. Sunday when drivers were about to start their engines. The course takes at least two hours to dry. Rain was still falling at 4 p.m, making it too late to complete the 90-lap event before sunset.

The track stretches nearly 2½ miles around 11 turns and has several elevation changes.

NASCAR rescheduled the race for noon Monday. Last week's race at Pocono also was moved to Monday because of rain.
