"Due to the equestrian environment he has been in, he has kept his condition really well and his appetite has been second to none," Jusufovic said.
"He has thrived in that environment.
"This prep has been an opportunity to get his body right and build him up.
"It's been a really good prep and the only hiccup really has not been able to have a start in five weeks, otherwise it has been faultless."
The time between runs is a little concerning for Jusufovic, but he believes Pinstriped is the best horse in Saturday's race.
"I believe I've kept him up to the mark," Jusufovic said.
"The horse is sound and fit, and I suppose the concern is the length of times between runs, but it looks a good race, I feel."

Saturday's race is part of the VRC/CRV Winter Championship Series that has a final at Flemington on July 3, but Jusufovic is not looking any further than Saturday's outing.
"I'm taking it run by run," Jusufovic said.
"So, we'll see how he goes, and we'll make a decision after he runs on Saturday."
