Shamrock Rose, seizing the lead shortly after the start, shrugged off a sustained challenge from Avie’s Mineshaft and rolled to a 4 1/2 length win in Saturday’s $100,000 La Lorgnette Stakes at Woodbine Racetrack.

The La Lorgnette, a 1 1/16 mile race for three-year-old fillies, attracted a field of 10 and Shamrock Rose was the 5-2 favourite as one of three Mark Casse-trained entrants along with Miss Mo Mentum and Hanalei Moon.

Shamrock Rose cut out all the fractions in the La Lorgnette, getting the quarter in :24.98, the half in :49.66, three-quarters in 1:14.10, and the mile in 1:38.07 before stopping the clock in 1:44.37.
