There were three mares offered in foal to Yarraman Park’s champion sire I Am Invincible at the Magic Millions National Broodmare Sale on Wednesday and they ended the day as three of the four most expensive mares sold.

She won the Group I ATC The Galaxy (1100m) last year and lightning fast Toronado (IRE) mare Mariamia was back in the spotlight when selling for $1.8million.

Bred by Adam Sangster, Mariamia came from humble beginnings making just $18,000 for Swettenham Stud at the Inglis Premier Yearling Sale Book 2 in 2018 before earning her stripes on the track during her early years in Victoria with Shane Stockdale when she showed the promise of better to come.

Newhaven Park bought the mare through Inglis Digital in March of 2022 for $335,000 and sent her to Joe Pride which proved a master stroke.

Mariamia made rapid progress for her new trainer working through the grades to win the Group II ATC Expressway Stakes beating Group I winner Golden Mile and then scored her career defining win in the Galaxy.

Retired to stud at the end of last season, Newhaven Park sent her to I Am Invincible and offered Mariamia in foal to the champion sire at the Gold Coast with Zhijun Zhao the purchaser at $1.8million, so she will join the stampede of top class mares headed to Yulong in Victoria.

“We bought her to go to Xtravagant and we put her in work to race. She proved to be a lot better than that and she improved into the autumn and won a Group One,” said John Kelly.

“Then we brought her up here, after sending her to I Am Invincible in early September and she sold terrific.

“It is a wonderful price. It has probably exceeded our expectations. When you get up to that level, how do you know what horses are worth? It is a matter of who wants to win.”

Consigned by Yarraman Park, Biscayne Bay was snapped up by Yulong via their Panthalassa Syndicate for $1.2million and was in foal to I Am invincible having missed to the champion sire in her first year at stud in 2022.

Placed in the Group I VRC Oaks, Biscayne Bay comes with a big pedigree as a half-sister to Group II winner Tenley from the family of Golden Slipper winning sire Vancouver with her third dam the Group I winning blue hen Skating.

“We thought she was really well bought,” Yulong’s Troy Stephens noted. “She’s a gorgeous mare, a Sebring mare, a stakes winner.

“She ran third in an Oaks and she’s carrying a beautiful pregnancy.”

The third mare offered in foal to I Am Invincible was Zoustar’s Group II ATC Reisling Stakes-winner Glistening, who made $950,000 for Morningside when purchased by Kia Ora Stud.

There are two more mares to be offered on Thursday in foal to I Am Invincible, who has just ticked over $30million in seasonal earnings.
