The presence of Vancouver will not deter trainer Gerald Ryan taking on the Golden Slipper winner with King's Troop in the San Domenico Stakes.

The well-bred colt won at Warwick Farm last Wednesday at his second start to earn the chance at stakes company.

That may happen in Melbourne with Ryan to enter him in the Vain Stakes at Caulfield on Saturday as well as the San Domenico at Rosehill.

Both Group Three races for the new season's three-year-olds are over 1100 metres.

"Vancouver might frighten a few away and we could get a small field which could be an advantage," Ryan said.

"I'll put him in the Vain and discuss it with (owner) John Messara but I'm favouring the San Domenico because it's on his home track.

"He is still maturing and this will probably be his last start before he goes for a spell.

"I think he will be much better in the autumn and he won't go deep into the spring.

"The only other race for him coming up is a benchmark 67 and he is now a 69."

King's Troop is closely related to Snitzel who Ryan trained to win the 2006 Oakleigh Plate.

Haptic, Headwater, Redzel and Japonisme who run in the San Domenico are vastly more experienced than King's Troop who made his debut on July 18.

Godolphin's Haptic won his first two starts including the Listed Lonhro Plate before finishing 12th in the Golden Slipper.

Headwater, trained by Hawkes Racing, won the Silver Slipper and finished fifth in the main event while the Peter and Paul Snowden-trained Redzel finished third in the Group Three Kindergarten Stakes at his only stakes class appearance.

The Chris Waller-trained Japonisme has won his past three starts including the two-year-old handicap at Rosehill in which King's Troop finished second.

Vancouver is unbeaten in four starts and will run in a barrier trial on Monday ahead of his return.
