Leading stallion Sebring, winner of the 2008 Golden Slipper, has died aged 13 of a heart attack at Widden Stud.

The Magic Millions Guineas is back on the agenda for Sebring Sun who has been cleared of injury after a disappointing effort at Randwick.

Sebring Sun gets the chance to prove he can be a Group One force when he runs in the Up And Coming Stakes at Randwick.

Trainer Gary Portelli is confident Sebring Sun will prove himself worthy of a Golden Slipper campaign when he returns at Randwick.
