Danny Shum Chap-shing warmed up for a big weekend in two countries when producing former Australian galloper Sports Legend to score a dominant win at Happy Valley on Wednesday night.

The veteran handler will chase a feature double on Sunday, with Helene Feeling and Chill Chibi set for the HK$26 million BMW Hong Kong Derby (2,000m) at Sha Tin and Victor The Winner contesting the Group One Takamatsunomiya Kinen (1,200m) at Chukyo in Japan.

Shum was in Japan to oversee Victor The Winner’s crucial track gallop on Tuesday morning before returning home for the Happy Valley meeting.

“It’s a busy week,” Shum said. “[Japan] was OK, not too bad but quite cold over there and windy. The track is good, very firm, but they forecast a bit of rain on Sunday.”

Sports Legend relished a drop in class to claim his first Hong Kong victory in the Class Four Craigengower Cricket Club Challenge Cup (1,200m) for Angus Chung Yik-lai.

Stalking the leader Super Axiom in running, the well-backed $4.5 second favourite cruised to the front at the top of the straight and surged clear to win by four and a quarter lengths.

Sports Legend was unplaced in his first five starts in the city – all at Class Three level – but showed promise in Australia with two victories from seven starts.

“He was good. He got the draw [three], he was dropping into Class Four and he got to claim five [pounds] with Angus – he got everything,” Shum said.

“I was hoping he could win like that because the owner [Boniface Ho Ka-kui] gave me a mission to win the HK$1.5 million bonus in Class Three, so I hoped he could win well to make me confident he could win in Class Three.”

Chung capped his night with victory on Tony Cruz’s Colourful Emperor in the Class Three Tin Lok Handicap (1,200m), backing up his double from Sha Tin last Saturday.

Earlier on Wednesday night, Colourful Prince recorded the same winning margin as Sports Legend in his effortless Class Four Canal Handicap (1,000m) triumph.

Sent forward by Luke Ferraris from barrier 11 to lead, the Douglas Whyte-trained gelding ran his rivals ragged in a slick 56.68 seconds.

It was the son of Per Incanto’s first turf win, with his two previous victories on the all-weather track at Sha Tin.

“Totally surprised,” Whyte said of Colourful Prince’s massive winning margin.

“He’s done a good job. The draw looked awkward, but once he got to the fence and the lead, he got comfortable and he ran a good race.

“The problem with him is when he gets too competitive with another horse [in front], he overuses himself and then he has nothing left at the end.

“But he got a soft time of it today, he ran them off their feet, he got them uncomfortable and that was the winning margin.

“He’s going to go up significantly [in rating] now because of the margin.”

Benno Yung Tin-pang struck early on an even night of racing, claiming a double in the first four races with impressive winners Dragon Pride and High Percentage.

David Hayes also prepared a brace courtesy of Red Majesty in the first section of the Class Four Percival Handicap (1,650m) and Samarkand in the Class Three Russell Handicap (1,650m).

The Australian handler was narrowly denied a treble in consecutive races, with Strongest Boy beaten a nose by Courier Magic in the second section of the Percival Handicap.

Courier Magic made it back-to-back wins for Jamie Richards and Ben Thompson, having delivered the Australian jockey his maiden Hong Kong success two weeks earlier.
