Kevin Blake backs three contenders for Royal Ascot day four, aiming to extend two earlier winners. His top choice for the Commonwealth Cup at 11/1 is Aidan O’Brien’s CHARLES DARWIN, a No Nay Never son who impressed in the Norfolk Stakes before a setback. Blake says the market undervalues the colt despite a recent Navan win today.

In the Sandringham Stakes, Blake backs Donnacha O’Brien’s GLYFADA, a Camelot daughter who has won two of three starts and flourished when dropped to a mile at Killarney. He trusts her fast stride and ability to handle a pace. For the King Edward VII Stakes, Blake picks Aidan O’Brien’s CAUSEWAY, a striding Wootton Bassett son who has risen from a handicap win to a Group 3 victory.

Blake’s selections reflect a blend of form and market insight that could swing betting volumes on Ascot’s most lucrative day. A successful Charles Darwin run would boost his credibility after two earlier winners, while strong performances from Glyfada and Causeway would underline his knack for spotting emerging talent. The three picks offer punters clear targets as the festival reaches its climax.
