NATURAL GEM (3) made a winning track debut in her penultimate start and then doubled the dose by scoring even more easily last time out. Rocky Cheung keeps the ride and will take 3kg of her back. She is again nicely placed and can complete the hat-trick. TREBLE MAKER (7) finished second fresh up at Pinjarra-Scarpside and then was too good here 8 days ago, scoring by over a length, despite racing keenly in the running. She drops 6.5kg in weight, which makes her among the hardest to beat again. SCIENCE DEGREE (4) showed her preference for her home track when scoring fresh up by nearly a length, when leading all the way. He will be looking to attempt similar front-running tactics from his good draw, and another win immediately is not beyond him. SURE THING (1) posted a hat-trick of wins at Esperance before finishing fourth at Ascot 6 weeks ago. He is nicely placed back at this level and is capable of a top 3 finish.
