PLANETARIUM (1.05) really could have his rivals seeing stars if, as expected, he delivers a knockout punch in Newmarket's Zetland Stakes.

Trainer Mark Johnston nearly always targets the extreme twoyear- old test having won it before with the likes of Double Trigger and, 12 months ago, 9/4 favourite Empire Day.

Not many youngsters are sufficiently robust to endure such a rigorous examination of stamina, but Planetarium proved he was up to the job at Pontefract last month.

Contesting a race of identical mile-and-a-quarter-distance, the rugged son of Fantastic Light made every yard to gallop the opposition into a senseless stupor.

Johnston's other runner, Double Attack, might be worth a saver, although not before you've seen her make it to the start at a steady canter.

The erratic filly has been causing her Middleham handler a fair few headaches, notably when unshipping the jockey and bolting prior to her most recent outing.

If Double Attack does stop throwing the toys out of the pram and get down to business, there's always the outside possibility she could spring a mini-surprise.

Over at North Yorkshire's other major training centre of Malton, Noel Wilson's horses are in pretty good late-season nick.

Noel sends a couple of juveniles up to Ayr, Pavershooz (12.55) and Red Skipper (1.25), both of whom warrant each-way support.

Pavershooz made an encouraging debut at York, staying on in eye-catching fashion to occupy fifth spot in a much warmer heat than today's John Smith's Maiden Stakes.

In the case of Red Skipper, he has the advantage of being dropped in trip, plus given a break by the handicapper, which might help him win the six-furlong Nursery.
