Cosmic Sun chose the perfect venue to shed his maiden tag as he sprang a 66-1 shock in the King George V Stakes at Royal Ascot.

Richard Fahey's three-year-old had failed to get his head in front on any of his previous 10 starts, but was pushed up to challenge for the lead in the straight by Paul Hanagan.

The more strongly fancied Chiberta King came at him inside the final furlong, but Cosmic Sun found plenty for pressure to score by a length and a quarter.

Barwell Bridge was back in third, with the John Oxx-trained favourite Zarinski in fourth.

Hanagan, who was securing his first Royal Ascot winner, said: "We had our hopes up in the Queen Mary yesterday but Rose Blossom was disappointing and this shows how up and down the game can be.

"When he ran at Musselburgh last time, he ran out on the bend and didn't handle the track but he didn't put a foot wrong here."

Fahey added: "I couldn't say I fancied him at 66-1 - he was still a maiden until now - but he had run some good races."
