Rosmartini can continue to vindicate the faith of trainer Simon Miller when she tackles the Westspeed 3YO Handicap (1400m) at Belmont on Wednesday.

Miller predicts a bright future for the daughter of Proart and expects her to figure prominently in three-year-old features for fillies at the upcoming Ascot carnival.

Miller made the boast after Rosmartini scored a runaway maiden win at Belmont in June when she led and put 4 3/4 lengths over her nearest rival.

That sparked a run of three straight wins for Rosmartini with a fifth placing to boom gelding Man Booker when on debut the only blemish on her record.

Rosmartini will carry 56kg with the claim of Aaron Mitchell, who retains the ride after guiding her to victory over Forever Diamonds (1200m) at Belmont 14 days ago.

Forever Diamonds, a member of the powerful Grant Williams team, franked the form with a dominant maiden win at Northam on Monday.

Miller believes Rosmartini, bred at Korilya Stud and raced by managing part-owner, John Wilberforce, with a Fremantle Dockers syndicate, will be hard to beat.

“The form around her is good, it doesn’t look an overly strong race and she gets in nice at the weights,” said Miller on TABradio.

“This is a nice stepping stone for her and I would like to think she can get the job done.

“If she gets through tomorrow (Wednesday) then I will step her up again.

“After this run she will progress to Saturday grade”

Rosmartini, against a field of nine starters, will jump from barrier three.
