Alcaldesa floored punters yesterday when she shed her maiden tag with a boilover win in the Listed HS Dyke Wanganui Guineas.
The outsider of the field turned the form book upside down with her late lunge for victory at the expense of the local hope Perfect Harmonee and the favourite Lucky Edie.
The result continued the excellent Guineas run of Alcaldesa's co-breeder, part-owner and trainer Tony Bambry.
"She's a half-sister to Lord Turbo, who won the race two years ago, and it's a race we've targeted," he said. "It's on our back doorstep."
Bambry also produced another filly in Acquisto, a maiden at the time, to finish third at long odds in the feature 12 months ago.
