Aide Memoire coped admirably with a sharp rise in class to strike the first stakes-winning blow of her fledgling career.
The four-year-old took on open company for the first time in the Listed James Bull Rangitikei Gold Cup and she passed the test with flying colours for the fifth win of her 11-start career.
"It was a big step up for her, but she only had the 53kg," Marton trainer Fraser Auret said.
Aide Memoire had won her previous start at Otaki where she carried five and a half kilos more to a runaway victory against Rating 75 company.
The Remind mare has only once failed to earn a cheque with that unplaced effort on a heavy Awapuni track last winter.
