It's a Dundeel will have an important gear change in Saturday's Randwick Guineas and will wear blinkers for the first time.
Cambridge trainer Murray Baker decided the race was the ideal one to test the blinkers in an attempt to get It's A Dundeel to settle a little closer to the pack.
The Spring Champion Stakes winner is residing with Baker's son Bjorn at Warwick Farm where this year's Guineas (1600m) will be run because of construction work at Randwick.
Bjorn Baker has experienced group one wins in partnership with his New Zealand-based father and although he is now out on his own at Warwick Farm, he can claim some of the credit if It's A Dundeel wins the Guineas.
"We know he can finish off his races as well as anything but, hopefully, the blinkers will help him be a bit closer," Baker said.
"Murray has always done this with horses like Lion Tamer and Harris Tweed.
It's the first time for Dundeel and, hopefully, it makes him more tractable.
"He gets too far out of his ground and he can't do that at Warwick Farm.
"It's not the best track for him but it's like his home track now and he's had quite a few course proper gallops to get used to it."
It's A Dundeel started favourite in the Victoria Derby but finished seventh, beaten almost five lengths, after again getting a long way back.
