The Tony Cruz-trained I’m A Witness gets a rare chance to dominate in the Police Cup (1,200m) at Happy Valley on Wednesday night which makes him clearly the horse to beat.

Perhaps his record could look a little better than two wins from 21 starts but I’m A Witness (Joao Moreira) has nevertheless been a model of consistency, when the draw or luck in running has allowed, and that is borne out by his statistics – he has finished second, third or fourth placings on another 13 occasions.

He hasn’t been doing a bad job anyway, with a win and close second over 1,200m at the Valley the yield for I’m A Witness at his last two starts, but gets circumstances here to help him improve on his record.

Moreira takes over from Silvestre de Sousa and looks to have an opportunity that his fellow Brazilian has not had, and that is to take control from the start of this Class Three trophy.

The event looks to have little in the way of regular speed. Many of the runners prefer to sit back off the speed and some others with some pace are poorly drawn and may prefer to sit back or will work hard to get forward.

Moreira gets horses out of the gates fast and that should see I’m A Witness able to cross the two horses under him who do have some speed, A Beautiful and All My Gain, and find the rail. Once there, he will hold all the keys to the speed and Moreira can set it to suit himself in front or, in a pinch, take the box seat.

Beauty Generation’s sharp trial keeps the Derby dream alive

His danger could be All My Gains (Derek Leung Ka-chun) dropping back in trip from a good draw. The grey had to do way too much early work from a wider draw last start at Sha Tin over 1,400m, has the speed to be in touch and is always competitive in these sorts of races with no weight.
