It was mission accomplished for Tony McEvoy at Rosehill on Wednesday as import Le Roi confirmed his standing as a stayer on the rise in the Group Three Summer Cup.

McEvoy said autumn targets were undecided for the promising galloper but it's next year's spring Cups that are in the South Australian trainer's sights.

Le Roi's three-quarter length win in the 2400m contest capped a preparation which has netted four straight wins.

It has also seen Le Roi overtake fellow imports from the McEvoy team as the trainer's leading prospect for next year's spring carnival.

Le Roi was one of four horses bought from Europe last year to join the McEvoy team.

"He's probably come from fourth in the run," McEvoy said.

"I reckon he's first now."

McEvoy targeted the Summer Cup as Le Roi's first test at 2400m and the victory will set a platform for the stayer to run in richer races.

"It ticks a few boxes this race," McEvoy said.

"But he'll have a very light autumn-winter. His main goal will be next spring."

Instead of spelling Le Roi, McEvoy says the horse will stay in work without racing.

"I've got a beautiful property up on the river Murray where I can lead them off the pony and swim them in the river," McEvoy said.

"He'll just have a freshen up there for six weeks but he'll work every day and I'll decide on what to do."

Le Roi, sent out a $2.40 favourite, settled third in the seven-horse field and came through along the inside.

Runner-up Brightest performed well on a quick back-up after racing on Saturday while Praecido came in another 1-1/2 lengths away third.

Jockey Glyn Schofield made it a feature summer double on Le Roi after winning the Group Two Villiers on All Legal last Saturday.

He believes the stayer has a bright future.

"For a horse that stays well and has only had a handful of starts, it was a very good win," Schofield said.

"I think Tony knows what he's got and he's in for an exciting time with this fella."
