Absent from racing action post-Blue Diamond, Streisand’s case for Saturday’s Golden Slipper has grown stronger through later developments, trainer Clinton McDonald affirms.

Chayan’s emphatic win in the Group 2 Reisling Stakes at Randwick on March 7 particularly gratified the Cranbourne handler, endorsing the Blue Diamond form.

Runner-up to Streisand in the Group 2 Blue Diamond Prelude, Chayan then ran behind her and select rivals in the Group 1 Blue Diamond on February 21, heightening McDonald’s anticipation for the $5 million Rosehill Group 1.

McDonald holds that his filly by Magnus merits status as her generation’s premier filly and looks forward to her validation in the weekend’s 1200-metre test.

“We’ve met her twice and beaten her twice,” McDonald said of Chayan.

“I feel my filly is the best filly in the land at the moment and she’s probably the best two-year-old, because she’s been the most consistent from the spring to the autumn.

“She’s had five starts for two seconds, two wins and an unlucky fifth on the track where you couldn’t make ground. She’s been consistently good the whole way through.”

Coming off a Group 3 Blue Diamond Preview fifth, Streisand captured the Blue Diamond and Blue Diamond Prelude, after close losses in spring’s Listed Maribyrnong Trial and $500,000 Inglis Banner.

In the Golden Slipper field this year, only Streisand and Shiki have five starts apiece, which McDonald regards as beneficial amid the four-week gap.

Courtza, handled by McDonald’s father Ross for the 1989 Diamond/Slipper double, is one of three Slipper winners in 40 years succeeding from a four-week-plus break.

Sepoy (2011) is the only post-Courtza horse – a colt – to win both Blue Diamond and Golden Slipper among five total two-year-olds.

Manikato, prepared by maternal grandfather Bon Hoysted, also notched the double in 1978.

“I followed a bit of the same path as dad did with Courtza and we’re going straight to the Slipper (from the Blue Diamond), but we feel that she’s got the race smarts and the race sense to be able to do that,” he said.

Streisand has gate 11 for the Slipper, possibly 9 barring emergencies three and four, her gate 10 Diamond victory bolstering McDonald’s draw faith.

“It was a slow tempo, but she still sat wide and sprinted off it, so I think she’s in it right up to her ears,” he said.

“She can race on speed, she can race back, she goes on wet and dry. She’s got no chinks in her armour.”

Ben Melham, her Blue Diamond jockey, rides Streisand again in pursuit of a second Golden Slipper following She Will Reign’s 2017 win.
