Jamie Walter's Proven Thoroughbreds has secured naming rights to the Group Two Guy Walter Stakes named in honour of his late brother.

A multiple Group One winning trainer, Guy Walter died suddenly in May 2014.

The following year the Australian Turf Club renamed the Wiggle Stakes to recognise Walter's contribution to NSW racing.

Walter was also the primary trainer for Proven Thoroughbreds which now spreads its horses among several leading trainers including Joe Pride and John Thompson in Sydney, Steve O'Dea in Queensland and John Bateman at Goulburn, all of whom had a personal connection to Guy.

"We've always wanted to sponsor a race and the Australian Turf Club has kindly helped facilitate this fitting synergy," Jamie Walter said.

"The whole family was very touched when the ATC named a race after Guy who not only had a tremendous influence on racing in Australia but was also pivotal in the evolution of Proven Thoroughbreds.

"So I am naturally delighted to sponsor such a race and preserve the legacy of Guy and Proven Thoroughbreds as a single entity."

The 1400m race for fillies and mares will be run at Randwick on March 3.
