It was the turn of Douglas Whyte to leave Happy Valley last night with a wide smile as a winning treble took him back to the top of the jockeys' championship in the title battle that is dominating local racing. Whyte took a back seat last Saturday when arch rival and defending champion Basil Marcus rode four and his young rival landed just one - and a one-day suspension which is now subject to appeal. But it was Whyte who was hot at the city track, beginning with an opening race success on Smart Dragon (2-1 favourite). This was quickly cancelled out by Marcus who produced Multi Colours (3-1 favourite) with an impeccably-timed run to win the Classes Four and Five, 2,200-metre second event. Marcus came close in the third where Whyte was down the track on favourite Right On (7-2) but then the pendulum swung back in the challenger's favour when he took the final two races on the card. Regular ride Barish (5-2 favourite) looked almost a standout in the Class Five, 1,000-metre sixth event and Whyte made no mistakes. The Ivan Allan-trained sprinter was held up just off the pace and then came through well under Whyte to prove too strong for Speed Cat (10-1) in the run to the line. Respected local trainer Wong Tang-ping had supplied Whyte with his opening race success and he was on hand to lead in Roaring Star (5-2 favourite), impressive winner of the final event. There was plenty of pace on in the Class One longer sprint, supplied by Classic Jester (25-1) and Optic General (10-1). Whyte, in predatory fashion stalked them from fifth place, and fired up the winner on straightening. The winning margin was a half length but final supremacy was not established until the last 20 metres when Roaring Star, a quality galloper, began to go away from them. Classic Jester did well to hold on for second from Optic General who had looked a major chance at the turn under regular rider Jimmy K.H. Ting. A clearly pleased Whyte said: 'It sums up racing, doesn't it? I thought I could have a good day on Saturday and Basil gets four winners. I was happy with my book of rides tonight and it has worked out really well. 'I was hoping for this sort of a night and it has turned out that way. But there's a long way to go.' Whyte now leads Marcus by one winner, having now chalked up 71 for the season. There was a very welcome success for another well-established South African jockey when Felix Coetzee, on his 60th ride since his last win, finished powerfully on Diamond And Gold (5-1 favourite) to land the wide open fourth event. It was Coetzee's strength which prevailed, getting up in the final few strides to touch off Take Charge (7-1) who looked like giving Marcus another vital win. Female claimer Willie W.Y. Kan had taken the previous event on bottomweight Grand Prize (14-1) and underlined the fact that horses do run along for her. She won by a neck from Mission Sealed (6-1) with Always Cheerful (10-1) finishing a further short head away third.
