It will be a light night for Douglas Whyte but champion jockey Basil Marcus is quite all right. That is the position of Hong Kong's top two riders, who were the root cause of the recent rule change involving retained jockeys which operates for the first time at tomorrow night's Happy Valley meeting. On a seven-race card no retained jockey can take more than two outside rides, with the result being that Whyte has four mounts while Marcus will be seen in action in six of the seven races. Whyte and compatriot Felix Coetzee, attached to a stable with under 40 horses, were expected to be prime sufferers and yesterday's declarations reflect that view. Whyte's retaining trainer Ivan Allan starts just two horses, with the young South African rider taking his permitted two outside rides from regular supplier, trainer Wong Tang-ping. 'It was always going to be like this so I can't say that I did not expect it,' said Whyte. 'Ivan has just the two running so I end up with four rides. Had it been under the old rules, I would have had a full book. But I just have to get on with it.' Marcus rides four for champion trainer David Hayes, leaving him to partner two outside rides for John Moore. Interestingly, he rides Universal Star for Moore in the fourth event, even though Hayes has two runners. Marcus, leading the battle for this year's title and riding splendidly, said: 'I don't think the new rule is going to affect me as much as I first thought it might. David has plenty of runners, so I will have rides. Six out of seven races at Happy Valley is fine.'
