It is said that a week is a long time in politics - but a day is a longer time in racing.  Take last Saturday at Rosehill for instance.

Before the first race, Sepoy was a hot favourite and the filly Satin Shoes was considered another top chance for the $3million Golden Slipper Stakes which will be run on April 2.

But the colt and filly had their colours lowered and while they probably had valid excuses on the wet track, their defeats opened up speculation on the upcoming Slipper.

This Saturday, the Pago Pago and Magic Night Stakes offer the final chance for horses to qualify for a Slipper start.

Probably the most significant prospect is the Patinack Farm-owned Pane In the Glass. Currently 24th in the order of entry, she clearly needs a win in the Magic Night to ensure a berth in the world's richest two-year-old contest.

On the other hand, You're Canny, a top chance for the Pago Pago Stakes isn't entered for the Slipper and trainer Gratz Vella is more intent on setting his youngster for the Sires Produce. You're Canny, of course, emerged as a promising type with his defeat of the slick filly Karuta Queen in the Black Opal Stakes.

From a Slipper point of view, I am not prepared to discard Karuta Queen. She clearly wasn't herself when defeated in the Black Opal and her previous form was so authoritative that the double figure odds remain appealing.

THE ONLY bone of contention regarding Friday night's William Reid Stakes is the winning margin for Black Caviar.

While we all know there are no absolute certainties in racing, surely Black Caviar cannot be beaten. General consensus is more a matter of whether she will be beaten ever - and whether she'll ever get to the Ajax odds of 40-1on.

Ten straight wins is an enormous effort and she really looks capable of anything. A boom galloper is good for racing and Australia is blessed to have Black Caviar and More Joyous - two equine "sheilas" with stunning appeal and potential.

Many may be baying for a match race between the two. But I reckon the longer they are kept apart, the better because it will be sad, even an injustice, to see either beaten.

NEW ZEALANDERS have an enormous opinion of Jimmy Choux, a top contender for the Rosehill Guineas. In fact, Jimmy Choux and another New Zealand-bred Absolutelyawesome share favouritism for the feature race for three-year-olds.

Jimmy Choux's high rating is understandable coming off four in a row in his home country, capped by a stylish effort in the New Zealand Derby a fortnight ago.  Meanwhile, Absolutelyawesome was a game fourth in the Randwick Guineas at Warwick Farm on the same day.

While you have to respect the Kiwi, I think the Victorian visitor, Domesky, is capable to repelling the invasion from across the Tasman. Trained by Michael Kent, Domesky is not long out of Maiden class but he stamped his claims on a bright future with a win in the Alister Clark Stakes at Moonee Valley last Friday night.
