Troy Corstens has been involved with many big race wins but is chasing a first Group One victory in his own right as a trainer in the Queensland Derby.

Pinstripe Lane will be Corstens' first Group One runner when he steps out in Saturday's 2400m Classic at Eagle Farm and the trainer says he would not swap the colt for any other horse in the race.

Corstens, the son of veteran trainer Leon Corstens, has been general manager for Malua Racing at Flemington in recent years in a partnership with John Sadler who handled the training duties.

But Corstens has also kept his hand in by training his own team in recent months and is now the sole owner and trainer at Malua.

Sadler has returned to Caulfield where he will prepare a smaller group of horses within the framework of Aquanita Racing which shoulders the administrative duties for its trainers.

"As long as Pinstripe Lane runs well I'll be really happy. If I could win it, it would be out of this world," Corstens said.

After a strong win at Rosehill and a second in the Grand Prix Stakes at Doomben at his past two starts, Corstens is convinced Pinstripe Lane has had the right preparation to be a force in Saturday's feature.

"We've really set him for this," Corstens said.

"It's been the long term plan and it all looks like it's coming together. He is fit and well and spot-on. I don't think I can have him any better."

Pinstripe Lane shares the second line of betting with Elusive Runner at $4.80 behind Grand Prix Stakes winner Vilanova ($3.70).

Pinstripe Lane was promoted from third to second in the Grand Prix after stewards lodged a protest on behalf of connections.

They determined Pinstripe Lane was inconvenienced at the 200m by Rudy who beat Pinstripe Lane to the line by a nose.

Corstens expects Eagle Farm to suit Pinstripe Lane better than Doomben.

"He copped a little bit of interference and bit of bad luck (in the Grand Prix) but I still liked the way he hit the line. I thought it augured very well for getting him over to the bigger track at Eagle Farm," Corstens said.

"I wouldn't swap him for anything in the race at the moment. Whether he's good enough to win remains to be seen but I'm confident he's going to run a huge race."

Pinstripe Lane, who will be ridden by Damien Oliver in the Derby, will gallop on the course proper at Eagle Farm on Tuesday morning.
