JOLIET, Ill. — Rain has been the big winner so far this year on the DIRTcar Summer Nationals Hell Tour, and Mother Nature dealt another wet hand to the dirt late model tour on Saturday.

Wet weather forced the postponement of Saturday night’s scheduled event at The Dirt Oval at Route 66 Raceway. The event has been rescheduled for Monday, July 1.

With the exception of Brian Shirley’s win at Kankakee County Speedway on Thursday, three of the first four tour events have been hampered by rain – Peoria Speedway last Wednesday (now set for June 26), Sycamore Speedway on Friday (a rescheduled date for the 40-lap feature to be announced soon) and now Route 66.

By virtue of his victory at Kankakee, Shirley – a two-time Summer Nationals champion – leads the early points standings over Frank Heckenast Jr., Rusty Schlenk, 2010 Nationals titlist Jason Feger and Ryan Unzicker.

Fayette County Speedway in Brownstown, Ill., is next up on the Hell Tour slate with a $5,000-to-win main event scheduled for Sunday, June 16.
