In just four weeks time Gai Waterhouse will march into the $3.5m AAMI Golden Slipper boasting her strongest ever team of two-year-olds – 11 years after she claimed the trifecta in the world's richest juvenile race.

On that occasion she had five runners as classy trio Ha Ha, Excellerator and Red Hannigan filled the placings. Most experts said no trainer could ever repeat the unprecedented feat of saddling up the first three Slipper runners past the post.

Yet with 11 different two-year-old winners to her name already this season, Waterhouse is on track to rescale the dizzying heights she reached in 2001.

And it's not just the punters, who have backed four Waterhouse runners into the top five of betting with Tab Sportsbet, trumpeting the Tulloch Lodge charge.

Leading ratings analysts Timeform are also suggesting the queen of Australian racing could have up to eight starters in the race, most of which would jump as genuine winning chances.

Only one horse at this stage is considered capable of throwing a spanner into Waterhouse's supremely oiled machine – Blue Diamond winner and $4.40 Golden Slipper favourite Samaready.

Timeform rated her run to win the Blue Diamond at 123, just a point less then Sepoy's effort to win the same race last year before he went on to win the Slipper.

The next four horses on the Timeform ratings are all prepared by Waterhouse.

Silver Slipper winner Pierro leads the charge, and the Lonhro colt is expected to improve on the 118 he produced when winning upon resumption last weekend, incidentally becoming the first horse to officially qualify for the Golden Slipper.

Stablemate De Shamekh is surprisingly fifth of the Tulloch Lodge crew rated at 109 after his dominant win at Rosehill in January.

Pure Hustle, Kuchinskaya and Rampaging are next in line, while Later Gator could rocket up the list if she performs in Sunday's $250,000 Black Opal Stakes at Canberra.

Stable jockey Tommy Berry said he wouldn't be surprised to see half a dozen Waterhouse runners in the Slipper.

“It can definitely happen,” Berry said.

“She's run out of her stable jockeys but I'm sure there's plenty of people that want to ride them.

“She's probably got the best group of two-years-olds she's ever had and it's because she's done a great job at the sales.

“I think next year's going to be even better because the horses that she's been buying have been unreal.”

Part of Waterhouse's grand plan for her 2012 Slipper assault has been to keep her crack team of juveniles apart until the race itself.

That's why Pierro stepped out individually last Saturday, and will likely contest the Todman Slipper Trial (1200m) in two weeks before reaching his grand final.

This weekend Pure Hustle gets his chance in the Schweppes Stakes (1100m) at Warwick Farm and Later Gator heads to Canberra.

Raceway, who won the Canonbury Stakes (1100m) last start, goes around next weekend in the Skyline Stakes (1200m) before his tilt at the Slipper.

Kuchinskaya will likely run in either next week's Sweet Embrace Stakes (1200m) or the Reisling Slipper Trial (1200m) in a fortnight while Driefontein and No Looking Back are on track to head straight into the Slipper.

Berry takes the ride on both Waterhouse runners this weekend, and said Pure Hustle and Later Gator weren't too far off the impressive Tulloch Lodge juvenile quartet.

“They're not far behind the top four as in Driefontein and No Looking Back, and the two colts [Raceway and Pierro], but they're probably a couple of lengths off them at this stage,” Berry said.

“Pure Hustle is a pretty smart horse, I've always thought he's had ability.

“Last prep he tended to go quite keen as you probably saw when he won. Now he's relaxing quite well and showing a lot more fight to the line.

“I think he'll get through the wet track no problem. It's not a bad field but whatever beats him will be winning the race I think.

“Later Gator is going to have every favour with barrier two and a wet track so she's going to have no excuses.

“It's going to be a really good field [the Black Opal], but if Later Gator's going to be competitive in the Golden Slipper well she's going to have to almost win or be winning on Sunday.”

GAI'S TWO-YEAR-OLDS

PIERRO

Golden Slipper odds: $6.50

Won the Silver Slipper in very impressive fashion last weekend, botching the start before flashing home to finish over the top of them in the wet. That was five months after Gai Waterhouse boldly declared the colt as the Golden Slipper winner after he claimed the Breeders Plate.

RACEWAY

Golden Slipper odds: $7.50

Destroyed an open two-year-old field on debut in January, then was very gutsy as an odds-on favourite in the Canonbury Stakes. Plenty of upside is still expected.

DRIEFONTEIN

Golden Slipper odds: $13

Won the Magic Millions Classic on a protest from stablemate No Looking Back before going into the Widden Stakes as the well-backed favourite which she won, despite rearing in the barriers. Genuine Slipper winning chance.

NO LOOKING BACK

Golden Slipper odds: $9

First past the post in the Magic Millions Classic but lost the race on a protest. Then represented the Waterhouse yard in last month's Blue Diamond and was second to Slipper favourite Samaready. Yet to run a bad race and the Slipper shouldn't be any different.

DE SHAMEKH

Golden Slipper odds: NOT IN TAB SPORTSBET MARKET

Beaten by Diamond Earth in the Inglis Nursery on debut, then produced a devastating burst for home last time in to win in open two-year-old grade by 3.5 lengths. That run explains his lofty Timeform rating, but a few of his stablemates will likely leapfrog him heading into the Slipper.

PURE HUSTLE

Golden Slipper odds: $26

Was spelled instantly after winning easily on debut in October. Stepping out at Warwick Farm on Saturday after winning a trial by five lengths and his Slipper price could well be slashed in half by Monday morning.

KUCHINSKAYA

Golden Slipper odds: $26

Took three runs to get going but it was worth the wait as she smashed them by three lengths in an open two-year-old handicap at Rosehill last February. Will need to scrap some more prizemoney ahead of the Slipper, but will get her chance to do so later this month.

RAMPAGING

Golden Slipper odds: $101

Won a two-year-old midweek maiden at Canterbury last month quite comfortably but doesn't look up to Slipper grade.

LATER GATOR

Golden Slipper odds: $26

Has only had the one start which she won in pretty emphatic fashion on a wet track at Canterbury a month ago. Gets the chance to outline her Slipper credentials in Sunday's Black Opal Stakes at Canberra where she shapes as one of the main chances.

TUTUDUMONDE

Golden Slipper odds: NOT IN TAB SPORTSBET MARKET

Won a maiden at Hawkesbury last month in her only race start, but the Slipper looks well beyond her.

VALERIO

Golden Slipper odds: NOT IN TAB SPORTSBET MARKET

Stepped out in a midweek maiden at Canterbury last start on debut, winning by a nose. Hard to see her coming into Slipper calculation.
