Crunch time is looming in Australia for the Group One performer Summer Passage.

The Matamata-trained three-year-old's performance in the Gr.3 Caulfield Guineas Prelude (1400m) tomorrow will decide his immediate future across the Tasman.

"It's a crash-hot field and we'll know exactly where we are after the race," said Lance O'Sullivan, who prepares the Snitzel colt with Andrew Scott.

"He'll be telling us whether we press on to the Caulfield Guineas or maybe the Coolmore."


Last season's Gr.1 Sistema Stakes (1200m) winner and Gr.1 Sires' Produce Stakes (1400m) runner-up at Randwick finished a last-start eighth when he resumed in the Gr.2 Danehill Stakes (1200m) at Flemington.

"The run was a lot better than it looked," O'Sullivan said. "He was a bit lost down the straight and Mark Zahra had to take a hold of him when Limestone fell."

Summer Passage, who will again be ridden by Zahra, has taken benefit from the outing.

"He's doing really well and we're pleased with him," O'Sullivan said. "He's gone ahead and put on a bit of weight."

Meanwhile, on the domestic front the stable was further encouraged by the debut performance at Avondale on Wednesday of the highly-rated three-year-old Aero De Paris.

The son of Tavistock overcame the heavy ground to finish a close second after making the running.

Aero De Paris is owned by the Hong Kong-based Daniel Yeung, who also raced the New Zealand-bred Aerovelocity, an international Group One-winning sprinter for O'Sullivan's brother Paul.

Matamata conditioner Glenn Old holds a strong hand going into the Powerworx Greys at Pukekura Raceway today with Our King Sway, but there does remain a question mark about the topweight's fitness leading into the 1400m race.

The Taranaki Cup winner hasn't favoured the wet conditions over winter and has been plagued by feet issues in the lead-up to his campaign.

"I'd say we're only 80 per cent ready. But it's a small field so you'd think he'd be in the money anyway."

Meanwhile, he has every bit of confidence that stablemate Renminbi will clear maiden company today when he lines up in the Denis Wheeler Earthmoving Maiden over 1300m earlier in the day.
