Greenham Stakes
On his three-year-old debut, Mon Fils ran in the Greenham Stakes at Newbury, in which he finished third to Boldboy (who as a gelding, was not eligible for the classics) and the Dewhurst Stakes winner Lunchtime. On 5 May, Mon Fils was one of eighteen colts to contest the 175th running of the 2000 Guineas over Newmarket's Rowley Mile course. On rain-softened ground he started a 50/1 outsider and was ridden by the forty-six-year-old veteran Frankie Durr. Mon Fils led from the start and although briefly overtaken by Noble Decree, he rallied inside the final furlong to regain the lead and win by a head.
