Kawartha Downs regular Tommy Riley notched his first Ontario Sires Stakes win with the three-year-old trotting filly Millers Song tonight at Grand River Raceway in the $15,600 first Grassroots leg.

Louis Philippe Roy, the leading driver in Canada in terms of money won this year (and second in wins) was up behind Millers Song. Leaving from post seven he had her on top by the :30 opening quarter, continued to lead through middles splits of :59.4 and 1:30. They held off several challenges and managed to win by a head in 1:59.3 over Late Shift and Bustingattheseams who was a neck back in third.

Tommy’s wife Amanda owns Millers Song who was unraced last year at two and started her career at Kawartha Downs this year. She won her first two starts at KD before heading to Mohawk for her first stakes try in mid June. She led that mile as well and tired in the lane to finish third timed in 1:56.3.

She won again at KD, where she’s driven by Nick Boyd, on Canada Day. She now has four wins in seven tries. She is the lucky 13th foal of her dam and a sister to Designable ($570,000), Runway ($275,000), etc.

The Rileys, who generously share their pony Kokanee with Kawartha Downs’ race fans regularly, are back at their home track on Saturday night as they’ll start Royal Engagement in the second race from post one with Boyd up.

Post time is 7 pm.
