The win of Toffee at Happy Valley on Wednesday night, combined with the outstanding run of Lucky Stravinsky at Sha Tin last Sunday, should be more than enough to convince the doubters that last season's griffin form will stand up. The junior generation gets another test it should pass at Sha Tin this afternoon when Champion King makes his new season debut in race five under the guidance of Douglas Whyte. The early-market punters had no trouble working it out, either, as Champion King was a firm $35 favourite on last night's 6pm tote call. Champion King raced just three times as a griffin, with apprentice Alex Lai Hoi-wing having the mount on the first two occasions and Whyte taking over for a narrow but solid victory over 1,400m on May 1. Trainer Peter Ho Leung has given Champion King an unorthodox preparation, with a barrier trial over 1,700m at Happy Valley last Saturday as his major piece of work. However, the Danehill grandson looked very fit at the track this week and Ho, who trained the first winner of the new season, Pro Joy, last Sunday, should be vindicated. An unusually big bet has skewed the early tote call in the eighth event, where Regency Horse was listed as a $13 chance. The smart galloper will be at a much more realistic price today when the pool balances out but the big early bet is a good tip in itself. Similarly, Flaming Lamborgini is a short-priced $21 favourite for the feature event - race seven - but should get to a more realistic quote by race time. The fact Whyte has abandoned Aboriginal after their defeat last week has failed to deter punters in the fourth event. The Barathea five-year-old, who races in the colours made famous by champion Indigenous, led the market in a wide-open race at $52. David Oughton's Devon Flair, which Whyte chose ahead of Aboriginal, will make appeal at $84.
