Imperatriz defied critics after a lackluster trial at Cranbourne, showcasing her dominance with a first-up victory at Flemington, extending her winning streak to six.

Despite concerns post-trial, trainer Mark Walker remained confident, with Imperatriz proving her mettle during a recent gallop at Moonee Valley. Walker, focusing on her return and potential, acknowledged the mare's resilience and hinted at further improvement. As plans unfold, Walker and assistant-trainer Ben Gleeson will solidify autumn strategies for Imperatriz.

Opie Bosson, her regular rider, admitted to pre-race pressure but praised Imperatriz's resilience and determination, crediting her ability to find an extra gear when needed. Despite unexpected challenges during the race, Bosson's trust in Imperatriz never wavered, emphasizing her exceptional talent and their formidable partnership. Bosson's acknowledgment of Imperatriz's superiority reflects her dominance in the sprinting realm.
