For David Hayes, the equation is simple if he is to keep his faint hopes of a late charge at the trainers’ championship alive.

“I need to be training more winners than John [Size] at the next few meetings to have a sneak of a chance,” said Hayes, who trails Size by eight wins with only nine meetings left this season.

“It’s highly unlikely but I haven’t given up, for all that I’m a realist. If he equals me or worse on Saturday, I’ll hoist the white flag.”

A two-time champion Hong Kong trainer, Hayes cut Size’s double-digit lead to as little as four wins last month before the latter struck back to regain breathing space.
