Preferito will be out to add to a winning run at Ballarat Cup meetings for champion trainer Gai Waterhouse when the colt steps out in the Magic Millions Clockwise Classic.

Last year Carriages was Waterhouse's only runner at the meeting and the filly won the corresponding $200,000 race for juveniles.

A year earlier The Offer powered to victory in the feature Ballarat Cup.

Choisir colt Preferito ($3.20) will be the first of three runners on Saturday's program for Waterhouse and is second favourite to make a winning debut and give his trainer back-to-back wins in the sales-restricted race.

The 1000m race is run in the clockwise direction - opposite to usual Victorian races - and Preferito was sent south to continue preparations for the lucrative event after his third in a Sydney barrier trial three weeks ago.

"He's well-educated on his Sydney leg which is important and Gai has been down to Melbourne and watched him gallop last Saturday morning and was happy with him," Waterhouse's stable representative Mark Newnham said.

Hawkes Racing's Bring Me The Bling won a jump-out in the clockwise direction at Ballarat last week and is the $2.90 favourite.

Preferito is on trial for the $2 million Magic Millions Classic in January at the Gold Coast.

Unlike Carriages last year, Preferito heads into the race on debut.

"Carriages had had a run under her belt in Sydney first so he (Preferito) is giving away a little bit of experience, but he has shown similar ability," Newnham said.

The Waterhouse-trained Show A Star is $5.50 favourite for Saturday's $50,000 IGA Liquor McKellar Mile (1600m) while four-year-old Our Catch has been sent south to be given his chance first-up in the $100,000 Magic Millions 3&4YO Classic (1100m) off a Sydney barrier trial win last month.
