Nowadays, Norwegian-born William Buick is, effectively, the principal jockey for Godolphin in Britain, following the demotion of James Doyle from his previous position as first-choice jockey to the longest-serving Godolphin trainer, Saeed Bin Suroor, in September, 2016. Buick was signed by Godolphin, alongside Doyle, in November, 2014, and rode the first Derby winner in the famous royal blue silks, Masar, trained by Charlie Appleby, in 2018.
Prior to his Godolphin appointment, Buick had previously been stable jockey to John Gosden, succeeding Jimmy Fortune in January, 2010. He famously won the Group One Dubai Sheema Classic in Meydan, United Arab Emirates on Dar Re Mi on just his fourth ride for his new employer.
Buick began his riding career in 2006, at which point he was apprenticed to Andrew Balding, based in Kingsclere, near Newbury, Berkshire. In his debut season, Buick rode just ten winners, but increased his seasonal tally to 67 in 2007 and, in 2008, was involved in a ding-dong battle with David Probert, also apprenticed to Balding, for the Apprentice Jockey Championship. After 95 winners, Buick lost his claim in May, 2008, thereby giving Probert the chance to catch him. Andrew Balding said at the time, ‘They are at different stages of their careers. They aren’t taking each other on.’ Nevertheless, the title was not decided until the final day of the season and eventually shared by Buick and Probert, with 50 winners apiece.
