Rosehill is gearing up for one of the biggest days of the Sydney Autumn Racing Carnival – Golden Slipper Stakes Day led by five Group 1 races including Winx running in the George Ryder Stakes.

The meeting’s marquee race is the $3.5 million Group 1 Longines Golden Slipper (1200m) and the official 2017 Golden Slipper field is set for release on Tuesday morning.

Pre-field Golden Slipper Stakes odds at Ladbrokes.com.au have the fillies at the top of the markets with the undefeated Toby Edmonds-trained Queensland raider Houtzen ($3.80) nudging out She Will Reign ($4.60) for favouritism.

Prepared on the Gold Coast, I Am Invincible filly Houtzen has won all four of her career starts to date including the $2 million Magic Millions 2YO Classic (1200m) in January.

She bypassed a run in the wet in Sydney last time out and instead made history carrying 63kg to victory over 1000m at Eagle Farm in a blistering four length effort ahead of her Golden Slipper test.

One-time favourite She Will Reign is still being kept safe in futures Golden Slipper betting despite the Gary Portelli-trained Manhattan Rain filly going down as the beaten odds-on favourite last time out.

After winning her opening three career starts including the Group 2 Silver Slipper Stakes (1100m) at Rosehill on February 18, She Will Reign was run down late by Frolic on a Heavy (9) Randwick track in the Group 2 Reisling Stakes (1200m).

Given a gun ride down the far outside of the track, Michael Freedman’s Husson filly Frolic relished the mud course for her Reisling Stakes upset and currently pays $11 to bring that form into the Golden Slipper 2017.

The other best fancied at $8 is the Lindsay Park-trained Ladbrokes Blue Diamond Stakes winner Catchy ($8).

Not since Flying Spur (1995) has a Golden Slipper winner come off a non-Sydney lead-up, but the bookies are taking no chances with Fastnet Rock filly Catchy who is yet to taste defeat in Melbourne.

Co-trainer David Hayes prepared the filly Miss Finland (2006) for her Golden Slipper success and along with Catchy also has a big hope for the 2017 edition this weekend in Tulip ($11).

Tulip ran fourth to her stablemate in the Group 1 Ladbrokes Blue Diamond Stakes (1200m) on February 25 and franked that form in Sydney over the weekend.

Running at Rosehill in the final Golden Slipper lead-up the progressive daughter of 2012 Golden Slipper winner Pierro won the Group 3 Magic Night Stakes (1200m) by nearly two lengths.

In the past four years two fillies have beaten home the boys in the Golden Slipper results with Overreach (2013) and Mossfun (2014).

The last to come off a Magic Night Stakes run however was Calaway Gal (2^nd) in 2002.

The best fancied of the boys in Golden Slipper markets this season meanwhile is the Peter & Paul Snowden-trained Blue Diamond runner-up Pariah, the stable after successive wins after the success of Capitalist (2016) 12 months ago.
