Kevin Prendergast's charge just collared English raider Silca Chiave on the line to land the 300,000 contest.

The Shelbourne Hotel Goffs Fillies Five Hundred is next on the agenda for the winner. Supple was delighted to team up with his former boss for the Group 1 victory.

Johnny Murtagh was at the head of affairs throughout on the gelding and he stayed on strongly in the closing stages to hold off the challenge of Fields Of Joy by a neck.
'That will be him out of handicaps now,' said Halford. 'He could go for a Listed race but I've always had it at the back of my head to run him over hurdles. The 4-y-o hurdle at Listowel is a possibility.'

'That's always what he promised. He has always shown plenty at home,' said winning trainer David Wachman.
'He's big and weak and will make a nice horse next season. He'll probably have one more run - we'll throw him in at the deep end somewhere and see what happens.'

Blessyourpinksox continued the flying form of Peter Casey's yard when claiming the Listed Dance Design Stakes. Substitute Ted Durcan produced her with a strong run over a furlong out, before holding the late challenge of Ardbrae Lady by a neck.
'She did it well and he rode to instructions. The fast early pace suited her - they went a bit mad. She could go for the Group 2 Blanford Stakes here (Sept. 19th) - she likes this track,' said assistant trainer Francis Casey.
Kevin Prendergast completed a double on the card when newcomer Haatef ran out an impressive winner of the concluding K & M Timber EBF Maiden.
