Gai Waterhouse is in no rush to lock in a Doncaster start for today’s impressive Rosehill winner Niagara.

The lightly raced Niagara chalked up his second victory with an all the way win in the Group 2 $175,000 Hyland Race Colours Ajax Stakes (1500m).

Waterhouse has a high opinion of Niagara and was pleased to see him produce such a commanding win against the older horses but was non committal on a start in the Group 1 $2m Doncaster Mile (1600m) at Randwick on April 21.

“I’ve always had a great opinion of this colt. He was a most magnificent yearling with a great physic,” Waterhouse said.

“He was beaten a nostril in the Sandown Guineas when he wasn’t furnished. He is a particularly furnished colt now and whatever he runs in will hard to beat.”

“Will he run in the Doncaster? Let’s go and have a sleep on it and see how he pulls up in the morning.”

Tommy Berry crossed over from a wide alley and took Niagara straight to the front where he had an easy run and cleared out at the 300m, giving nothing else a chance, to win by three and a half lengths from Star Of Octagonal and Alma’s Fury.

In a wide betting race Niagara started the $6 favourite and gave Berry an easy win in the end.

“He put the race away after the first hundred. He was quick out of the gates, I quickly wrapped him up and put the brakes on and he relaxed well,” Berry said.

“I think he is just starting to switch on and the penny’s starting to drop. Today as soon as I pushed the button he went.”

Berry is keen to ride Niagara in the Doncaster if Waterhouse decides to go that way.
