A third of the Australian's yard is made up of unraced horses starting their careers in the middle of Class Four. Horses like Brave Kid, whose trials in both New Zealand and here have never suggested he will end up anything short of a Class Two horse. With the benefit of racing experience, that can even translate to something better.

That means another couple of wins to come, at least, and the Size yard is full of potential two- or three-time winners.

His other lightly raced victor on the weekend, Spinnaker, may not have quite the same scope but it still wouldn't be difficult to see him pick up at least another race in the near future. He stays and horses which race on-pace and can stay usually punch above their weight in this racing environment.

Last Wednesday at Happy Valley, Size produced newcomers Kowloon Pride and National Treasure, who were beaten, but both gave every sign they will win their share of races, too.

Championships are won or lost in Class Three and Class Four as a general rule and a yard full of these young, fresh prospects still makes Size very dangerous as he sets about a mid-season surge in the next few months.

With Brett Prebble having the wind of David Hall, Caspar Fownes and Dennis Yip Chor-hong under his wings, he has been with three of the form stables of the early term. Darren Beadman is entrenched with John Moore, Matthew Chadwick with Tony Cruz and many other yards already appear to have chosen preferences among the jockeys.

That is making it tough for those not aligned in any particular yard and means that Whyte's prospects will rely heavily on Size's unknowns. His B-52s, as John Moore likes to call them.

You can't eat potential and it doesn't win a championship but it is sitting there ready to explode in Size's team and if he surges, so will Whyte, and it will be game on for a classic match-up for the jockeys' title once more.

The bad news for Prebble is that Whyte has already got out of his system the once-a-season slow period he traditionally endures each term.
