There is plenty of value on offer for adventurous punters in the Jockey Challenge, but favourite Douglas Whyte still looks the likely winner. Eight jockeys have 10 rides or more, giving them all some hope, but Whyte's 10-ride book - including the shortest-priced favourite of the meeting - seems strong enough to deliver him the win. Whyte was marked $2.65 by bookmakers last night, and a string of three excellent rides late in the day will prove pivotal to his chances. In race seven, Whyte gets a chance at redemption on Holyangelholy, a John Size-trained three-year-old who was a tragedy beaten last time out when the champion jockey was trapped for a run in the straight. Drawn three on Holyangelholy this time, Whyte won't be taking any chances and should peel from a one-off position and stride away to help the promising galloper gain a well-deserved victory. In race eight - the Hong Kong Reunification Cup - Whyte partners Me Tsui Yu-sak's potential top-liner Wah May Star, who has drawn nicely in five. Classic Jewellery can clinch the Challenge for Whyte, with the Size-trained runner ready to show his undoubted potential in a Class Three. Whyte's top three rides are backed by a decent bunch of horses, including griffin Sichuan Express, who started 1.5 favourite on debut, when he was dismantled by star two-year-old Amber Sky. The grey should bounce back, and at least earn valuable place points in small field of inexperienced horses. Others with Jockey Challenge claims are Tim Clark, who has a full compliment of 11 rides and was as much as $7 last night, and Zac Purton ($11), despite him having just eight rides.
