Kingoftherockies faces a stern test when he goes for his seventh straight win this year at Northlands Park in Saturday’s $50,000 Sun Sprint Championship. The 6 1/2-furlong dash for 3-year-olds and up headlines a nine-race card that begins at 1 p.m. Mountain.
Included in the seven-horse field are last year’s local champion sprinter, Ready Racer, and Dougs Buddy, who is 5 for 6 in sprints in his 15-race career.
