Punters who had their money on Douglas Whyte on last Thursday's Jockey Challenge get the chance to claw back some of their losses and even show a profit today, with the Durban Demon being at more attractive odds and with a better book of rides. Whyte has a full book on the card and once again it's littered with winning chances, including a number provided by his 'Dream Team' partner John Size. Whyte's best chances look to be debutant Rare Treasure (race two), King Hesperus (race four), Watch What Happens (race seven), Ichiban (race eight) and Bejeweled (race nine). And his other five rides represent some useful each-way chances, too. He is quoted as $2.60 favourite to win the Challenge and that looks a much more realistic proposition than the odds-on given about him on Thursday when he found himself in wide alleys for the majority of the afternoon. Second favourite Marco Chui Kwan-lai ($6.00) may win the feature event, the Queen Mother Memorial Cup on Really Happy for his allocated trainer Tony Cruz, but he may struggle after that, while Brett Prebble ($6.50) also has a sound chance of taking the main race on Ever Bright, but the balance of his book look to be each-way hopes at best. A better value proposition might be Gerald Mosse, the Frenchman who looks to have genuine winning chances in Istide (race five, blinkers first time) and Mascot Fortune in the last, as well as second-tier hopes in Pacific Alliance (race three) and Top Top Light (race nine). The Jockey Club's fixed odds market last night had Mosse as fifth pick at $9.00.
