Trainer Bryan Guy has high expectations with unbeaten colt Castagnola but doubts the three-year-old can repeat his last-start demolition job when he attempts a hat-trick of wins at Eagle Farm.

Castagnola, who is part-owned by wealthy businessman Ron Wanless, scored one of the biggest victories seen in Brisbane for some time when he strolled to a 10-length win over 1200 metres in three-year-old company at Eagle Farm on January 3.

The son of Untouchable previously made his debut at the Sunshine Coast when proving too classy with a 2-1/2 length win over the same distance in maiden class on December 14.

Castagnola was ridden on both occasions by Ric McMahon who retains the ride in Saturday's Anchor In Handicap (1200m).

Castagnola, who is named after a municipality in Switzerland, scored easing down last start on a track rated a slow six but faces a tougher job on Saturday from barrier 16.

However, Guy doesn't believes Castagnola, a $220,000 buy at the Magic Millions Premier sales, is purely a wet-track wonder.

"It was a wet track last start but I don't think he's just a wet-tracker as he won quite well on a good track at Caloundra at his first start," Guy said.

"I think he's got a future but I doubt he'll be winning by 10 lengths again from barrier 16.

"He's got a lot of potential but this race looks a lot stronger."

Guy plans to give Castagnola a short break after Saturday's race to prepare for the Brisbane winter carnival.

"I'm really only keeping him going now to give him more race experience," Guy said.

"He's still a little green and the way he travelled last time he wanted to hang out on the corner.

"He'll improve after this preparation and a race like the Queensland Guineas in the winter might be a nice race for him."

The Group Two Queensland Guineas (1600m) will be run at Eagle Farm on June 6.

Guy had hoped to run Castagnola in last week's $1 million Magic Millions Trophy (1400m) at the Gold Coast.

"We accepted but got balloted out because he didn't have enough prizemoney," he said.

"I thought he was worth a chance in the Trophy race but we lost a bit of time with him earlier on when he went shin-sore."

Guy believes Castagnola will appreciate further ground next preparation and rates the Trevor Bailey-trained topweight Little Mel as his main danger on the weekend.

"It's a hard race but there looks to be a lot of speed in the race and Little Mel is probably our biggest worry," he said.

"I think he'll (Castagnola) get further later on. He's the type of horse who drops the bit and settles well and you can put him anywhere in a race."
