Chanse Vigen, with another steady night, forged into the aggregate lead Saturday at the GMC Rangeland Derby at the Calgary Stampede grounds.

Chasing Vigen, a 33-year-old driver from Grande Prairie, Alta., are defending champion Kirk Sutherland, Chance Bensmiller, Troy Dorchester, Kurt Bensmiller.

Picking up $6,000 in day money on a steamy night was Gary Gorst, who, working out the seventh heat, clocked in at 1:12.58.

Rounding out Saturday’s fastest times – Kurt Bensmiller (1:12.75), Vern Nolin (1:12.75), Rick Fraser (1:13.32), and Vigen (1:13.34).

Opening-night leader Mark Sutherland – who had upstaged his soon-to-be retired father, the legendary Kelly Sutherland, on Friday – dropped to 17th overall.

His dad, meanwhile, sits 23rd after two days of the $1.15 million event.

Racing continues Sunday at 7:45 p.m.

The Stampede concludes July 17 with the Dash for Cash, the championship heat worth $100,000 to the victor.

NOTES: In the sixth heat, Todd Baptiste’s rig ran into trouble heading into the final turn when his left wheeler ended up on the ground. Eventually, the horse got to his feet and was led back to the barns to be assessed by the on-site veterinary crew.
