Irish raider Lily's Angel wrestled the betfred.com Chartwell Fillies' Stakes from French hope Kendam in a cosmopolitan gathering for the Group Three at Lingfield.
Lily's Angel (4-1) is a credit to the Ger Lyons' stable, stepping up from a Kempton Listed win to scramble past Kendam by a short head.
"She was really struggling in the ground and it took her a long time to get going but she finished well," said jockey Gary Carroll.
Lyons' brother and assistant Shane said: "Her pure class has got her through. She absolutely hated the ground and she was wheelspinning, but in fairness to Gary, he got her balanced and took his time.
"She's in the Ballycorus at Leopardstown but she wants better ground and the Windsor Forest (now Duke of Cambridge Stakes) is in our minds."
Another Irish challenger enjoying a fruitful passage across the Irish Sea was the Tommy Stack-trained Scream Blue Murder, who got up close home under Wayne Lordan to land the Listed EBF Weatherbys Hamilton Insurance Kilvington Fillies' Stakes at Nottingham.
