Ross Wolfenden’s Keystone Rhythm notched her seventh win of the year Tuesday in Harrington Raceway’s featured $20,000 Mares Open in 1:54.2 over a sloppy racetrack.

The eight-year-old Camotion mare was sent for the lead from post six by Wolfenden, and together they led the field past the quarter pole in :27.2. The mare then marched to the half-mile in :57.1 and three-quarters in 1:26.1 before sprinting clear of her rivals by three lengths in the stretch. Lorrie Please sat second throughout and held on for the place position while Rock N Load was third.

Trained by Wolfenden, Keystone Rhythm boosted her career bankroll to nearly $300,000. It was one of five driving winners for Wolfenden.

Tony Morgan also had five wins, following a seven win night on Monday.
