Fresh from a stunning victory with Romantic Warrior in Japan, Danny Shum Chap-shing continued his superb Happy Valley season with a double at the city circuit on Wednesday night.

Still basking in the glory of champion galloper Romantic Warrior’s Group One Yasuda Kinen (1,600m) win at Tokyo, Shum surged to the lead in the Happy Valley trainers’ standings this term after Packing Power and Helene Warrior cruised to impressive wins.

The 63-year-old handler boosted his tally to 30 winners at the city circuit – more than double his Sha Tin turf haul of 14.

Caspar Fownes, who prides himself on his success at the Valley, moved to 29 winners after Daring Pursuit claimed Wednesday night’s Class Four Cricket Club Valley Stakes (1,650m).

Packing Power backed up his strong trial form to produce a smart debut in the first section of the Class Four Mount Nicholson Handicap (1,200m) under Zac Purton.

“He’s still very green and he can improve a bit more,” Shum said after Packing Power comfortably accounted for Circuit Seven by a length and a half.

“He’s not a superstar, but he’s got some talent. Hopefully he will improve next season. He might have a break now, but I’ll just talk to the owners.”

Helene Warrior recorded his first Hong Kong triumph in style, relishing a rain-affected track to cruise home in the Class Three Shouson Hill Handicap (1,650m).

Ridden by Lyle Hewitson, the Starspangledbanner colt settled third on the rail and booted clear after taking the lead at the top of the straight to beat Zoom Boom by two lengths.

“He loved a bit of soft ground and a strong pace was good for him because he could hit the line strong,” Shum said of Helene Warrior, a two-time British winner on soft tracks when known as Red Zone Hero.

“He’s got a good pedigree as well.”

Purton joined Shum with a double and delivered David Hall a brace of his own after also guiding Northern Beast to victory in the first section of the Class Four Wong Nai Chung Gap Handicap (1,650m).

Northern Beast was the second leg of Hall’s double after Karis Teetan booted home his improving stayer, Sharpen Bright, in the Class Four Tai Tam Gap Handicap (2,200m).

Cody Mo Wai-kit prepared his first ever double in the final two races. Happy Fat Cat defied his $49 quote in the second section of the Class Three Violet Hill Handicap (1,200m) under Ellis Wong Chi-wang, before California Touch led all the way under Matthew Chadwick in the first section of the Violet Hill Handicap.

Elsewhere, Australian jockey Ben Thompson booted home his sixth Hong Kong winner when he guided Ernest Feeling to an upset win in the second section of the Mount Nicholson Handicap.

Sent out a $31 chance, the Jamie Richards-trained gelding stormed home to beat Golden Champion by a length and a quarter.

“We had a pretty cosy run but the big thing was handling the conditions – wet track and had no issues on it,” said Thompson, who also returned to the winner’s enclosure on Lost Child at Sha Tin last Sunday.

“Jamie Richards has been a great supporter of mine since I landed here and it’s nice to reward him and get another winner.”

Meanwhile, quality sprinter Sight Success has been retired from racing after nine wins and HK$25.7 million in prize money.

The John Size-trained gelding recorded a career-best win when he upset star sprinter Lucky Sweynesse in the Group Two Premier Bowl (1,200m) last year, while he also ran top four in several Group Ones.
