Slippery day has mudlarks set to reign at Rosehill Gardens MUDLARK: A wet track will suit Red Tracer at Rosehill Gardens. RED Tracer and Frozen Rope, two of the most accomplished wet track gallopers in training, have track conditions made to order at Rosehill Gardens today. The rain that has swamped Sydney in the last 24 hours will ensure a heavy track surface for Silver Slipper Day. "We have had more than 50mls of rain but there is no surface water on the track," Australian Turf Club racecourse manager Lindsay Murphy said last night. The track is now a heavy (9) but the forecast is for rain to ease overnight and there will be isolated showers (today). It is a genuine heavy track but there is a good grass cover and it is certainly safe for racing. No horse racing at Rosehill today has a better record on heavy surfaces than Red Tracer, a hot favourite for the Group 3 $125,000 Millie Fox Stakes (1300m). She has had four starts on heavy tracks for four wins - and all at stakes level. Red Tracer won the Millie Fox last year on a heavy (9) and has also won the Toy Show Quality, James H.B. Carr Stakes and Dane Ripper Quality in similar track conditions. For good measure, she has also won her only start on a slow surface. The classy Chris Waller-trained Frozen Rope also showed she has returned to racing in top form when closing late for a half-neck second behind Steps In Time in the Breeders Classic two weeks ago. Frozen Rope has been racing in career-best form over summer, winning three of his five starts on firmer tracks. But he has won three of his four starts on heavy surfaces by big margins and he is poised for his first feature race win in the Listed $100,000 Parramatta Cup (2000m).
