Glass Harmonium could get another crack at Group company in the Ladbrokes Great Voltigeur Stakes following his Listed success at Royal Ascot.The Sir Michael Stoute-trained colt, beaten in the Craven and Dante Stakes this spring, won the Hampton Court Stakes and is now among 37 entries for the Group Two at York on August 18."We were absolutely thrilled with his performance at Royal Ascot and he has come out of the race well," said Peter Reynolds, racing manager to owners Ballymacoll Stud. "He is a nice horse but we don't exactly know where's he's going yet. The Great Voltigeur is a nice race and will come under serious consideration. We've had success in it in the past with Hard Top, who won it well. "So we have always liked the race and it would be extremely nice to have a horse good enough to win it this year, but it's all in the melting pot at the moment. "Glass Harmonium hasn't been over the mile-and-a-half trip - the furthest he has been is a mile and a quarter, in both the Dante and the Hampton Court."Ballydoyle handler Aidan O'Brien is responsible for 16 possibles in the list, while John Oxx has put in Irish Derby third Mourayan.Among the other entries are Henry Cecil's King Edward VII Stakes victor Father Time, Queen's Vase scorer Holberg and Godolphin's Italian Derby winner Mastery.
