Music Box (8-1) showed a great attitude under Ryan Moore to land the Japan Racing Association Sceptre Stakes at Doncaster racecourse.
Aidan O’Brien’s filly came into the race in good form having won a Listed contest at Galway before following that up with two placed efforts in Group 3 contests.
She finally bagged her Group win at the fifth attempt as she ran on strongly down the far side and was always holding her rivals as they approached the finish.
Eternally (6-1) ran on well to finish second, a length behind the winner, with Tomyris (11-2) in third. Talaayeb, the 7-2 favourite, was fourth.
Kevin Buckley, Coolmore representative, said: “Ryan was happy, they went a decent pace and she ran on well off the back of it.
“Her form has been good since Galway with two Group 3 places since then, so it was nice to get that one in the bag.
“We’ll get her home and see how she comes out of it before deciding on anything else.
“Let’s not forget that was her 16th start since March this year! She’s been a busy girl but she’s tough and a good looking filly.”
