Although Biloxi is about to turn five, his trainer Rick Worthington believes the best is yet to come from the talented sprinter.

The winner of five of his 10 starts, Biloxi will run at Randwick on Saturday looking for his third win from four starts this preparation.

Worthington has entered him for two races but says he is most likely to run over 1000 metres in the benchmark 80 rather than the open 1200m sprint.

A half-brother to dual Group Three winner Mahisara, Biloxi began his campaign with an 1100m win at Warwick Farm on Anzac Day.

After a fourth over 1200m at Canterbury, Biloxi went back to 1000m at Hawkesbury on June 3 and scored a stylish win.

"I'm leaning to the 1000 metre race but I will take a good look at the fields first," Worthington said.

"He is clearly a horse with ability but even though he is going to be five in August, he is still mentally immature and can get wound up before his races.

"I want to get some continuity with him and get him racing well. I think he can step up to the better races later on."

A well-known horse breaker and pre-trainer, Worthington is in the process of rebuilding his Warwick Farm stable after enduring more than two years of treatment for aggressive melanoma.

Worthington says his health has improved and he is keen to train more horses.

"I've got plenty of room for more horses and I still have a lot to offer," he said.

"I'm coming out of an ordinary period but I want to be competitive and I'm sure there are people who can see value in me as a trainer.

"I still have a farm where I pre-train and I love that. Horses are my life."

Kerrin McEvoy, who rode Biloxi to win at Hawkesbury, will be aboard again if he runs in the 1000m event with Sam Clipperton to ride if he contests the longer race.

There were 17 entries for the open sprint headed by Mic Mac on 59.5kg, half a kilo more than Unanimously and Zaratone while Biloxi is on the 54kg minimum weight.
