MELBOURNE Racing Club chief executive Brodie Arnhold wants to celebrate the spring carnival with a feature group 1 finale on each major race day, announcing on Tuesday the club would run Saturday's star-studded group 1 Memsie Stakes as the last of an eight-race program.

MICHAEL SHARKIE reports in THE AGE that although the news caught trainer Mark Kavanagh on the hop, with fears the Caulfield track may be too firm for the reappearance of his unbeaten mare Atlantic Jewel, news of a Memsie Stakes closer was well received by the industry.

It could lead to a widespread revamp of the structure of group 1 race days. ''We're looking to do it all spring carnival, a feature group 1 to end each day,'' Arnhold said. ''There's some really compelling data in terms of turnover in that timeslot to say that it is worth giving it a go. Look at greyhounds and the terrific growth in market share they have had in that timeslot. We need to have a presence there.

''We need to do this three or four times during spring so we can compare like for like against previous years.''

Moonee Valley pioneered the concept of a late group 1 when electing to shift the Cox Plate to a twilight timeslot in 2009 and then running the William Reid Stakes, featuring Black Caviar's Victorian farewell, as the final race of the night in March.

Arnhold believes the concept should be embraced by all clubs. ''We'll learn a lot more over the spring but with 10 group 1 winners likely to run on Saturday we will get a great idea of how it could work,'' he said.

Free-to-air broadcast data from Channel Seven also showed a significant ratings spike later in the afternoon, although Arnhold said the industry free-to-air broadcast partner did not pressure the club to make the move.

''They [Channel Seven] are keen to do it, especially for the Caulfield Cup meeting, and they've produced some incredible ratings data which obviously then opens up marketing and advertising opportunities to a wider audience,'' he said.

Arnhold stressed the plan had was not purely economically driven, with lengthy consultation with Caulfield track manager Jason Kerr.
