VETERAN sprinter Nelson's Pet (5-1) ended his career on a high note when he responded brilliantly to John Marshall to career away with the second event at Sha Tin last night. Nelson's Pet was giving the Australian ace the first leg of another winning double and trainer David Hill his 37th winner of the season. ''He's as game as they come when you consider that he's a nine-year-old. But he has been racing consistently well for a 10-pound claimer,'' said Hill. Nelson's Pet won handily from the desperately ridden Smile For Me (10-1) who got up for second from favourite Fast Forward (3-1). Marshall's second success came on Charity Spirit (7-1) in the Class Four seventh event over 1,600 metres - and it was another easy win. Charity Spirit was racing generously on the outside of Daiquiri (7-2 favourite) in the early and middle stages and simply swept to the front when the straightened. ''He went really well and I was never troubled at any stage. I knew I had the one on the inside covered and he went to the front and kept going so well that I couldn't see anything coming from behind to beat me,'' said Marshall. Super Delight (18-1) finished second with Daiquiri fading for third.
