Whoshe became only the second filly to win the Wanganui Guineas in the past 20 years with a decisive success on Saturday.
It was the third win in six starts for the daughter of Storm Creek-Lesley Coup, who cost Ohura owner Red MacDonald $5000 at a NZ Bloodstock weanling sale.
Whoshe is trained at Te Awamutu by Richard Otto and Mark Brooks, who also produced Myths And Legends to finish second in the Great Northern Steeplechase.
Whoshe has been nominated for the Two Thousand and One Thousand Guineas at Riccarton in November.
"She is a pretty tough filly and we will just see how she gets through her race on Saturday before deciding where she will go next," Otto said.
