"Both are in great condition coming out of the race," he said.
There were worrying moments post race for Baker when Lizzie L'Amour, expected to finish in front of Bonneval, dropped out from the 500m and was pulled up by Damien Oliver.
She was found to have suffered a bout of cardiac arrhythmia, where the heart rhythm suddenly and dramatically changes and blood flow is affected.
There is no lasting effect from the condition and Lizzie L'Amour will continue her Melbourne campaign.
"She'd been working terrifically well and we expected a big run from her," said Baker. "We expected her to beat Bonneval home."
Three factors need to be taken into account when assessing the Bonneval run.
Lizzie L'Amour was out of contention, as was joint favourite Star Exhibit who reared as the start was made and threw rider Mark Zhara out the back of the starting stalls.
The other joint favourite He's Our Rokkii turned in a shocker when he could have been expected to kick on strongly, after Dwayne Dunn set a cruisy tempo in front on him.
Balancing that is that Bonneval and Lizzie L'Amour were the only runners still sporting a winter coat in the parade, coming out of a wet and cold New Zealand winter.
The 1600m is well short of Bonneval's optimum distances. She is a dour stayer as she showed in drawing away from the opposition in the 2400m Australian Oaks in Sydney in the autumn.
