Last year's champion apprentice Josephine Gordon, who has made a seamless transition to the senior ranks this season, joined Hayley Turner as only the second female rider to partner 100 winners in a calendar year on the Flat in Britain when Thunderbolt Rocks struck at Wolverhampton.
Gordon, who at the start of the year relocated from Lambourn to Newmarket to join Hugo Palmer's powerful operation, had moved onto 99 winners when scoring on Boy In The Bar at Chelmsford last week and after a frustrating run since brought up the century on Saturday evening.
The 24-year-old, who had her first ride in the States last month when Unforgetable Filly was unplaced in Keeneland's Grade 1 Queen Elizabeth II Challenge Cup, rode 87 winners last year but has improved on that out of her claim this term, when highlights have included Group 3 victories on Koropick and Apphia.
Thunderbolt Rocks is trained by Hugo Palmer, and the winner was a landmark for him as well as he tweeted: "Thunderbolt Rocks becomes a landmark horse. 75 winners for 2017, our best yet, and more importantly 100 for Josephine Gordon. A huge effort all round."
Turner rode 100 winners in 2008 – also bringing up the landmark at Wolverhampton – while Silvestre de Sousa, Luke Morris, Jim Crowley, Ryan Moore, Joe Fanning, Adam Kirby, Danny Tudhope, Oisin Murphy, PJ McDonald and James Doyle are the male jockeys to have hit and surpassed that haul this year.
