Hot property: Coolmore's big buys chase elusive Slipper

The Longines Golden Slipper is worth $3.5 million. Coolmore bought Pierro for $40 million after he won the race. The Stud farms will try to buy the Slippers' winners after the races. Some of the winning colts already have some of Coolmores' big studs in their ownership.

Home Affairs and O'President were bought by Coolmore Stud for $520,000 each at the Inglis Easter Yearling Sale last year. Coolier Stud wants to develop the yearling colts into potential Golden Slipper contenders rather than buy them after they have won the world's richest juvenile race.

Home Affairs was an $875,000 Easter Yearling purchase by Coolmore. The Golden Slipper is one of the biggest races in the world. Home Affairs had opened at $13 earlier this week but he has drifted to $18 in latest betting. Coolier's two colts are going in opposite directions in betting now.

Skyline Stakes winner O'President has been one of the best-backed Slipper runners this week. Magnier expects both colts to run well. The heavy track conditions probably favour O’President. Chris Waller is happy with both his colt.

Marc Van Gestel is optimistic the Golden Slipper meeting will go ahead at Rosehill Gardens on Saturday. The weather bureau's forecast for heavy rain is causing concern. There has been 90ms of rain on the Rose Hill track in the last seven days. Up to 200ml of rainfall is forecast in Sydney on Friday night and Saturday morning. ATC's sophisticated Rose hill weather station gives racing officials renewed hope. The Rosehill track can absorb further rain through the race meeting. It has had 20mls of water during the day before.
