TONY Cruz swept to the top of the jockeys' championship with a Happy Valley equitrack treble last night, riding the winners of the final three races on the six-event card. The dynamic Cruz took full advantage of the absence of champion jockey and previous leader Basil Marcus who is in Tokyo representing Hong Kong in a Super Jockeys' Series event. The South African also misses Saturday's turf meeting at the same venue and could find himself clearly in arrears when he reports back for local duty at the Valley next Wednesday. Cruz struck with topweight Saafi, the 5-2 favourite in the fourth event, and then followed up with Team Valour (5-2 favourite) and Family Of Wah Yuen (5-2 favourite), the runaway winner of the final event. And visiting international riders Walter Swinburn and Alan Munro had the perfect starts to their three-month winter stints. Both rode winners, Munro striking in the opening event for trainer Geoff Lane with bottomweight Winning Colors and Swinburn following up in the second race when equitrack-loving Diamond Treasure (9-2) rediscovered his best form for a solid win over his favoured 1,400-metre trip. And the main event on the card, the Chinese General Chamber of Commerce Cup, went to Nervous Witness and jockey John Marshall, following up on their excellent win a fortnight previously in the presence of the Princess Royal. Cruz was at his polished but forceful best on Saafi and Team Valour while Family Of Wah Yuen was a credit to trainer Eddie K. C. Lo who had him turned out in impeccable condition. Saafi, a maiden going into the 1,600-metre fourth event, won tidily from Lung Huang Shan (4-1), who just held off a fast-finishing and eye-catching Paradise (20-1) who won't be long in winning. The question mark over Team Valour was whether he could handle equitrack - always a doubt when a young horse hits the synthetic surface for the first time. But Team Valour went well in the run for Cruz and he was able to sweep confidently to the lead as they straightened. Topweight Kwacha (9-2), kept wide by claimer Francis K. S. Lam, ran home stoutly enough but was never going to get to an impressive winner. Swinburn and Munro were bidding for doubles in the final event with the former partnering Holy Smoke (4-1) and the latter on Fun And Smile (3-1), who was the medium of a major plunge. Fun And Smile did not look happy on the surface and Holy Smoke could not get into the fast-paced race. Nervous Witness also continued the good run of the John Moore stable and lifted Marshall to just two winners adrift of Cruz and Marcus. It was the gelding's first equitrack run but he adapted well and was always looking dangerous behind 2-1 favourite Evasive Tactic, an equitrack freak. Marshall pounced on straightening and Nervous Witness was much too good in the run home.
