What we can say with more confidence is that Just Zain comes from a yard in good form. Trainer Jonathan Portman, based in Upper Lambourn in Berkshire, has sent out 46 winners already this season — that is a serious number, and it tells you this is an operation that knows how to have a horse ready to run on the day. When a stable is firing like that, even a first-timer deserves respect.
Beyond that, the honest answer is that nobody really knows what Just Zain is capable of yet. That is, in its own way, half the fun.
