Apprentice jockey Pietro Moran rode Mansetti to a wire-to-wire win in the $1-million King's Plate on Saturday in Toronto.
Moran, 20, earned trainer Kevin Attard his third Plate victory as Mansetti, an 18-1 pick, covered the 1 1/4-mile race in two minutes 3.38 seconds.
Tom's Magic was second, 2 1/2 lengths back, while Notorious Gangster finished third in the 13-horse field.
Moran earned the Plate victory in just his second start in the race. His father, David, also rode in the race aboard William T.
The second jewel of the OLG Canadian Triple Crown is the $400,000 Prince of Wales Stakes, which goes Sept. 9 at Fort Erie Racetrack.
Earlier, She Feels Pretty took the lead on the final turn then held off a hard-charging Diamond Rain to win the $750,000 E.P. Taylor turf event by a head.
