SOUTH African star Douglas Whyte helped himself to a 700-1 treble at Sha Tin last night to cement second place in the jockeys' championship and, even at this late stage, have Basil Marcus glancing over his shoulder. Whyte, who rarely leaves either Hong Kong track empty-handed, scored a dramatic, last-stride victory in the final event on Super Fit (7-1) to complete the treble initiated by veteran Call Me Horse (10-1) in the Class Six, third event over 1,200 metres. The middle-leg winner was Helene Treasure (10-1) in the fifth event. It left him nine winners behind compatriot Marcus, who was indisposed for his final three rides, but it is virtually impossible for Whyte to collar the multiple champion with just four meetings remaining. The final event saw Super Fit come storming home to touch off Millennium Reigns (7-1) in yet another exciting finish. The Class Two, 1,400-metre contest saw a huge plunge for On Diamond Hill, whose odds fell from 23-1 to 6.2-1. He was given a faultless ride by Stanley K. M. Chin, but could finish only third. Favourite Double Expresso (7-1) was cannoned into by Take Charge, but no fault could be laid at the door of South African Piere Strydom, who rode the David Hayes-trained galloper. Call Me Horse was having his final race, and Whyte got him up in the last bound to touch off Make My Day by a neck, with the same margin back to third-placed Jonka (35-1) in the low-grade affair. It was a frantic finish to the first leg of the Triple Trio, with topweight Horse-Laugh (8-1) and Make My Day (7-1) both looking great winning hopes 200 metres out. Helene Treasure (10-1) responded admirably to Whyte in the Class Three, 1,400-metre fifth event, where there was eventually a head margin to Gainsborough's Boy (10-1), with odds-on favourite Citadel (8-5) a similar margin back in third place. Helene Treasure was a surprising transfer from the stable of Patrick Biancone to Ricky P. F. Yiu, who had taken plenty of time before starting him for his first run under his handling.
