[6] In an unusual seasonal debut for a classic contender, Our Lassie was matched against older horses in the Lincoln Handicap over one mile on 27 March.
Although the filly had been "off her food" for a few days before the race, Joel decided to run her as she was set to carry only 84 pounds and had already been backed to win £100,000 from the bookmakers.
The race was a rough one, with Dazzling being brought down after a collision with Sun Rose at Tattenham Corner, at which point the 33/1 outsider Ladies Mile led from Hammerkop with Our Lassie in third.

[9] A week after her Epsom victory, Our Lassie started 13/8 favourite under a weight of 106 pound for the Manchester Cup over 1+1⁄2 miles but finished fourth of the eleven runners behind the colt Zinfandel.
