You're so good at stud - Happily the latest winner for ace mare

Could You'resothrilling, the daughter of Storm Cat who won the Cherry Hinton Stakes in 2007, come up with black-type performers with all of her first five foals?

The remarkable achievement looks on the cards after her two-year-old filly Happily claimed a comfortable victory on her second start in a 7f Curragh fillies' maiden on Friday.

Happily holds an entry in the Moyglare Stud Stakes but Donnacha O'Brien, who partnered her to victory for his father Aidan, said we might not see the filly hit peak form this year.

“She's a lovely filly,” he said. “She was very green the first day but learned plenty from the run.

“We probably won't see the best of her until she is three, but she is one to look forward to.”

You'resothrilling produced Classic winners from her two first foals, as Irish 1,000 Guineas heroine Marvellous was followed by champion two-year-old colt and dual Guineas winner Gleneagles.

Then came Group 3 CL Weld Park Stakes scorer Coolmore and Listed Leopardstown 2,000 Guineas Trial runner-up and Group 3 Killavullan Stakes third Taj Mahal.

All of the dam's offspring are by Galileo and were bred by Coolmore partners. The mare has no yearling but was covered by Coolmore's perennial champion sire again last year.

Gleneagles now stands alongside his sire at the operation.

You'resothrilling, who also finished second in the Albany Stakes at Royal Ascot, is taking after her own dam Mariah's Storm by producing a slew of black-type horses at paddocks.

A 26-year-old daughter of Rahy, Mariah's Storm is also responsible for 'iron horse' and six-time top-flight winner Giant's Causeway, Cork and Orrery Stakes third and leading New York sire Freud and further stakes performers Butterflies, Hanky Panky, Roar Of The Tiger, Tiger Dance and Tumblebrutus.

Mariah's Storm also produced the dams of Tattersalls Gold Cup and Jebel Hatta winner Decorated Knight and Irish Derby runner-up Storm The Stars.
