In-form mare Princess Rhaenys scored a narrow victory in the Listed Tattersall's Gold Crown (2143m) at Eagle Farm on Saturday as the well-related daughter of Iffraaj scored a richly-deserved maiden stakes success.

A two time stakes-winner at the end of last year, the Tony Gollan trained I Am Invincible gelding Zarastro has been performing a little below par this preparation, but bounced back to his brilliant best to post a career highlight win in the $200,000 Group III Tatts WJ Healy Stakes (1200m) at Eagle Farm on Saturday.
