Among the winners at Sandown, Aidan O'Brien also took the training honours at a subdued Leopardstown on Saturday.
King's County showed plenty of courage to make his debut in the EBF Maiden a winning one, battling well when headed by the more experienced, and heavily supported in the betting market, Marsh Harrier to win by a neck under a determined effort by apprentice Paul Scallan.
Seamus Heffernan rounded off a successful week in which he finished second on Glyndebourne in the Irish Derby and riding four winners at Bellewstown when landing the Mount Eagle Maiden on O'Brien's Chimes At Midnight.
Kermiyana added to her success in a Gowran Park maiden when making it two wins out if two in the Listed Natural Gas Energy Rated Homes Brownstown Stakes.
She headed her front-running stable companion Kerataka over a furlong from home and went clear to win in good style from outsiders Sand Partridge and Topsy Morning.
John Oxx said of his winner,'She has been in season all week and she is still in season, but it did not seem to have any adverse effect. She deserves a chance at Group level, and may go for the Desmond Stakes at the Curragh now'.
Grinkov, trained by Pat Hughes, will take his chance in the Ulster Derby at Down Royal next Thursday following his last gasp success under Fran Berry in the Ask For Gas Handicap.
Jim Bolger's Citizen Edward looks set for a significant rise in the ratings after he completed a hat-trick of wins in the Woodley Handicap. He is another entered for the Ulster Derby but is unlikely to run.
