Saffie Osborne secured a landmark victory aboard Highwayman in the 250th running of the Betfred St Leger at Doncaster on Saturday. The rising jockey, called up by trainer Joseph O’Brien earlier this week, partnered the 11/1 outsider to a commanding two-length win in the oldest British Classic race.

Highwayman, a three-year-old colt, initially pulled hard in the early stages before settling in midfield under Osborne’s control. The field set a strong early pace led by Aidan O’Brien’s Christmas Day, the 7/4 favorite, and Action. Making steady progress two furlongs out, Highwayman seized the lead decisively, overtaking Action and holding off persistent challenges from rivals in the closing stages.

The colt’s better-backed stablemate, Enceladus, mounted a late surge but was unable to catch Highwayman, who maintained composure to secure a memorable triumph. Amelia Earhart, priced at 22/1, finished strongly to claim third place, while the favorite Christmas Day faded to ninth.

Osborne expressed her astonishment after the victory, saying she never expected to ride in the race, let alone win it. She credited Joseph O’Brien and his team for their confidence and acknowledged the support of her agent and family. “I didn’t have this on the bingo card for this week,” she said. “It means the absolute world and I’m in shock.”

Elsewhere at Doncaster, Charlie Appleby’s Desert Castle impressed in the Group 2 Betfred Champagne Stakes. The Godolphin trainee, sent into stakes company for only his second career start, overcame a slow start to overtake front-runners Sergei Diaghilev and Gentle Hurricane. Under jockey Billy Loughnane, Desert Castle powered clear in the final furlong to win by three lengths, with Breacher finishing third.

Loughnane described the colt as straightforward and relaxed, noting he showed a strong finishing kick and still appeared raw with untapped potential. “He’s a horse for the future,” Loughnane commented.

In other feature races, Geoff Oldroyd-trained Air Force One captured the Portland Handicap with jockey Clifford Lee aboard. The 11/2 shot tracked the leaders throughout and edged past Twilight Calls in the final furlong to win by half a length, while Al Shabab Storm finished a neck behind in third.

Tom Marquand and trainer William Haggas combined to win the Park Stakes with More Thunder, the 4/5 favorite, who took advantage of the drop back to Group 2 class to secure the victory.

The day's results highlighted emerging talent across jockeys and equine prospects in British flat racing.
