It was a third 2000 Guineas win in four years for Appleby, after victories for Coroebus (2022) and Notable Speech (2024).
Buick chose Ruling Court, an impressive six-length winner in Dubai in March, over last year’s champion juvenile Shadow Of Light.
“It was a hard choice for William, but he saw it right. He thought this horse would see out the mile trip and he outstayed them,” said Appleby.
Ruling Court is about 5-1 second favourite for next month’s Derby at Epsom, behind The Lion In Winter – who won the Acomb Stakes at York last August when the Guineas winner was third.
