“He's come back (from the winter) a tremendous horse and I'm impressed at his work.

The six-year-old's best was far too much for his opposition on Saturday, crossing 1-1/4 ahead of favourite Siege of Quebec and another 3-1/2 lengths to Rod Quinton-trained Boss Lane.
He'll face a bigger test in his next assignment – either in Melbourne or back at Randwick in a fortnight for the Group Two Tramway Stakes.
But trainer Kris Lees isn't sure if his campaign will include a run for the spoils at The Everest on October 13.
“He's a little underrated,” Lees said.
“He's played at the highest level for a long while and it's good to see get a win. If the Everest happens, it happens.
“There are races either side or he could get to an Epsom.”
Le Romain's last win came in the Group One Canterbury Stakes in March last year.
Before dropping back to Group Three grade for the first time in 18 months on Saturday, he'd raced placed six times at Group One and Group Two level.
