Mark Walker‘s champion mare Imperatriz cemented her legendary status by claiming a historic victory in the 2024 William Reid Stakes at Moonee Valley.

This win marks her 10th Group 1 victory and a successful defence of her 2023 title.

The New Zealand star bounced back from a runner-up finish in the Newmarket Handicap under a hefty weight.

Returning to her beloved Moonee Valley track, where she remains undefeated, Imperatriz entered the 1200m William Reid as the clear favourite at an odds-on quote of $1.70.

Ridden expertly by Opie Bosson, Imperatriz settled comfortably midfield before launching a powerful move in the straight.

Despite a late surge by 70/1 roughie Johnny Rocker, Imperatriz’s class shone through as she crossed the finish line first.

“It’s a relief,” Walker admitted after the race, highlighting Imperatriz’s perfect Moonee Valley record (5-for-5).

This victory makes Imperatriz the seventh horse to win the William Reid Stakes twice and the fifth to achieve the Black Caviar Lightning – William Reid double in a single year.

“I’m glad she showed her true ability,” Bosson said, confident in Imperatriz’s future prospects.

With this dominant win, Imperatriz joins Apache Cat (2008-09) as the only back-to-back William Reid champions.

Black Caviar is the other latest two-time winner having saluted on non-consecutive years (2011, 2013).

Bosson also celebrated his 98th Group 1 victory, likely adding more to his tally with Imperatriz by his side.
