Trainer Simon Miller was in Melbourne celebrating his 40th birthday, but at Belmont he received the perfect gift when Rosmartini claimed the second leg of a feature race double that has her earmarked for major races at the upcoming Ascot summer carnival.

Producing an almost identical performance to her Belmont Oaks (2100m) triumph 10-days ago, Rosmartini, expertly rated by record-breaking jockey, Jason Whiting, led throughout to win the Belmont Classic (2200m) in gritty fashion.

The Proart filly was challenged by Senso over the final 100m, but fought on determinedly to defeat the Paul Jordan-trained gelding by a half length with another length to third placegetter, Jetoomy.

$2.10 favourite and Dayana Plate victor, Juicing Carrots, ran fourth after having every opportunity of chasing down Rosmartini in the straight.

Stable representative, Kyle Nowland said Rosmartini, who improved her record to five wins from 12 starts and boosted prizemoney to just under $200,000, was delivering on her potential.

“She always showed us that once she got over this distance and with a little bit of maturity she was always going to perform well,” Knowland said.

“She really looked the winner a long way from home and went on with the job.

“I think she will go for a spell and look at some of the staying races over the carnival.

“She has earned that right to have a go at some of the better races.

“She might be a Perth Cup horse.”

Rosmartini gave Whiting his fourth Belmont Classic, going past Paul Harvey as the most successful jockey in the Listed feature.

The experienced hoop won previously with Miss Tipsy Topsy (2011), Empire Dancer (2005) and Dexian (2002).

Whiting said Rosmartini had given him an arm chair ride throughout.

“When she found the front she felt comfortable in what she was doing,” Whiting said.

“I thought someone would kick up and pressure her.

“She always felt like she had something to give.

“On straightening I thought something would have to be good to go past her.”
