The trainers’ championship battle took another decisive swing as Danny Shum Chap-shing collected a double at Sha Tin on Sunday to move two clear of Caspar Fownes at the top of the table.

On a day where Romantic Warrior was, to many, a slam dunk in the Group One Champions & Chater Cup (2,400m), Shum also watched Packing King maintain his unbeaten record for the stable in section two of the Class Four Standard Chartered Corporate & Investment Banking Handicap (1,200m).

The Darci Brahma galloper has thrived since joining Shum from Pierre Ng Pang-chi, making a winning stable debut in April, and he is showing no signs of slowing down with another strong performance one month later.

Sitting on the shoulder of long-time leader Silver Spurs throughout the journey, Zac Purton made his move at the 300m pole and gained the winning break on the field, ultimately winning with more in hand than the one-and-a-half length margin suggests.

He is one to follow for the rest of the campaign and could become crucial to Shum as the championship really begins to take shape with 14 meetings to go.
