TOP CLAIMING rider Jerry Chau is capable of reaching another milestone in his short but highly- successful career when he arrives at Happy Valley on Wednesday. 21-year-old Chau has raced to 43 winners in only his second season as an apprentice, and needs just another two wins to see his claiming allowance drop from seven to five pounds. With his card marked in seven of the nine races, and five rides for his mentor Douglas Whyte, his chances will be high of achieving that feat.
