Will a filly prevail in Saturday’s $1 million King’s Plate Stakes at Woodbine? It’s well within the realm of possibility. Contested at a distance of 1 1/4 miles on Woodbine’s all-weather Tapeta Footings surface, the King’s Plate is restricted to 3-year-old Thoroughbreds bred in Canada, and it’s Canada’s equivalent to the Kentucky Derby. But whereas only three fillies have won the Kentucky Derby, the King’s Plate has been won by fillies on 39 occasions, including six times since 2011.
