The Ontario Sires Stakes rolled into Grand River Raceway on Monday evening, and the tandem of driver Bob McClure and trainer Dave Menary dominated the event.

Three-year-old pacing fillies were in the spotlight at the Elora, Ont. oval as they did battle in six Grassroots divisions.

The Bob & Dave Show started with upsetter Westsluckycam posting a nose decision over This Day Forward in her assignment. The daughter of Camluck-Terror Of The West got away ninth and remained at the back of the bus through the opening half. She picked up cover in the backstretch and rolled three-wide at the three-quarter pole. Race favourite This Day Forward sliced out fractions of :27.3, :56.4 and 1:26.4, but she couldn’t fend off the late-driving Westsluckycam in the final stride. Third-place finisher Life Groove came up just a head short in what turned out to be a wild finish.

The daughter of Badlands Hanover-Free Admission was treated to a ground-saving journey for the majority of the mile, but she shook loose late and stormed home in :29 to win by a half-length margin over Selling The Dream. Specialcelebration rounded out the Triactor ticket.
