John Moore deflected all the praise to Brett Prebble, with whom he shared a double, for his strong-arm ride on his first winner and lamented a Mercedes-Benz Derby that came too soon for his other.
Moore said Prebble's use of the whip was key to Supreme Knight's victory, with the under-done four-year-old needing some extra motivation down the stretch.
'That was all about Brett and it was about the persuader,' he said. 'He got a gun run in behind, but it was just a matter of when, in that last little bit, whether he was going to bottom out or not, but Brett got everything out of him.
'The horse has not reached his peak yet, there's further improvement to come, especially fitness-wise, then he'll go to the mile, which I think is more ideal.'
Prebble described the effort to carry top-weight as 'tough' and said the slight gelding could be better off when he jumps into Class Two next start.
'I thought he was going to win more easily than he did in the end. But he had to give away weight to second and third and it was a tough effort under circumstances. He might be a horse who will be better for a rise in class and a lighter weight because he isn't a robust sort and he's a bit of a nerve nut.'
Packing Whiz was a rare Italian purchase by Moore, the Premio Parioli-Italian Two Thousand Guineas one of four wins from eight starts as a two and three-year-old.
