The Yorkshire Oaks at York runs on Friday August 21 — a Group 1 over a mile and a half for fillies and mares that is the natural next target for Diamond Necklace, the unbeaten Nassau Stakes winner from Glorious Goodwood last Thursday.
Diamond Necklace — Six From Six
Diamond Necklace won the Nassau Stakes at Goodwood at 4/5 as Horse Racing Oracle AI's NAP of the day — £10 returned £18.00. Six wins from six starts. The form book ranked her last of five in the Nassau field before she won. The AI's consensus disagreed. The record now reads six from six, unbeaten, at Group 1 level.
The Yorkshire Oaks is a mile and a half — three furlongs further than the Nassau Stakes over ten furlongs. The step up in trip is the first significant change in conditions for her. Aidan O'Brien's fillies have regularly won the Yorkshire Oaks over the past decade, and Diamond Necklace's breeding — as a daughter of an O'Brien-trained sire — suggests the stamina for the extra distance is there.
The Wider Field
The Yorkshire Oaks regularly attracts older mares with established form at the trip — horses who have run in the Nassau, the Epsom Oaks, or the Irish Oaks earlier in the season. Any filly who ran well in the Epsom or Irish Oaks and is now at her seasonal peak carries a competitive claim, particularly if she has proven York-specific form.
How to Bet the Yorkshire Oaks
Diamond Necklace will likely start as market leader given her perfect record and the quality of the Nassau Stakes win. Win-only at the expected price is the correct approach for those who follow the form. Each-way only makes sense for rivals at 5/1 or bigger with a specific form edge — a filly whose Oaks or Irish Oaks form has been underrated by the British market or whose York form specifically gives her a track advantage.
