Yarraman Park bred and sold 5yo Winning Rupert mare Seonee claimed her biggest prize to date when taking out the Group II SAJC Queen of the South Stakes (1600m) at Morphettville on Saturday.

Ridden by Billy Egan for Patrick Payne, Seonee had to chase down the leader Legacies and then was strong to the line working clear to win by a length and a half.

Seonee advances her record to nine wins, three seconds, and two thirds from 22 starts with earnings of $592,055.

She was an $80,000 Magic Millions purchase for Prime Thoroughbreds from the Yarraman draft so has proven an outstanding investment for her owners.

“We’re absolutely thrilled. We’ve got a heap of owners here,” Prime Throughbred’s Joe O’Neill said.

“She’s just a lovely mare. We didn’t pay much for her, and she’s been fantastic. Paddy Payne, what a training performance, and Billy Egan, what a ride.

“She’s a lot stronger now than what she was. Who knows, next year the Coolmore Classic or races like that. She’s a much better mare when we can get a wet track, but we just haven’t had them.

“Full credit to Yarraman Park that bred her. We buy a lot of horses off Yarraman and have a lot of success.”

Seonee was bred and offered for sale by Yarraman and is the best of three winners from Not A Single Doubt mare Mowgli, a half-sister to the champion Hong Kong sprinter Beat The Clock.

Mowgli produced a filly by Hellbent last spring and is back in foal to him again.
