In-form three year old Mackintosh will head trainer Chris Waller’s four runners in the Group 1 $600,000 Channel Seven Queensland Derby (2400m) at Eagle Farm on Saturday.

Mackintosh heads the betting for the Queensland Derby at $4 at Ladbrokes.com.au after winning three from three since being transferred to Waller’s stable.

Waller’s other Queensland Derby runners will be last start winners Encosta Line ($8) and Rodrico ($17) as well as Multifacets ($26).

Mackintosh made it three wins for Waller from three starts when he raced on the pace to record a solid win over Eagle Way and Howard Be Thy Name in the Group 3 $150,000 Mullins Lawyers Grand Prix Stakes (2200m) at Doomben last Saturday.

Mackintosh’s other two wins for the Waller stable were in a 1500m BenchMark 77 Handicap at Hawkesbuty on April 30 and in the Group 3 $125,000 Mitty’s Rough Habit Plate (2000m) at Doomben on May 14.

A decision to run Mackintosh in the Queensland Derby was initially put on hold after his win in the Grand Prix, but Waller confirmed in the middle of last week that the three year old would take his place in the blue riband for the colts and gelding.

“We have also made the decision that Mackintosh will definitely run in the Queensland Derby,” Waller said.

“We are very happy with the way that he has come through his winning run in the Grand Prix over the 2200m-distance and having seen him come through the race and having a good look at his profile, we have no doubt that he will run the 2400m.”

Grand Prix Stakes placegetters Eagle Way and Howard Be Thy Name are also among the first acceptances for the Queensland Derby.

While Eagle Way will be stepping up to the 2400m for the first time, the Darren Weir trained Howard Be Thy Name will have no trouble running out the distance after winning the Group 1 $500,000 South Australian Derby run over 2500m at Morphettville on May 14.

Blake Shinn has been aboard Mackintosh for his two wins during the Brisbane Winter Carnival in the Rough Habit Plate and in the Grand Prix Stakes and will ride the gelding in the Queensland Derby.

Hugh Bowman has returned to Australia after riding in Japan for a month and will take the mount on last start Rosehill winner Encosta Line who was scratched from the Grand Prix Stakes because of a blood irregularity but Waller said that the three year old had not missed any work and will line up in top condition in the Queensland Derby.

“Hugh Bowman will ride Encosta Line in the Queensland Derby, Blake Shinn will ride Mackintosh, Joao Moreira will ride Rodrico and our other Derby runner is likely to be Multifacets.”
