Son Pak Fu became the first galloper to register four consecutive Happy Valley victories this season when he gapped his Class Three Incheon Handicap (1,200m) rivals by three lengths on Wednesday night.

Both Sunday’s Group One Chairman’s Sprint Prize (1,200m) favourite Lucky Sweynesse and February’s Classic Cup (1,800m) champion Super Sunny Sing have strung together four successes at Sha Tin this term, but Benno Yung Tin-pang’s Son Fak Pu is the first to accomplish the feat at Happy Valley.

Sent off the $2 market elect on his first outing in Class Three following back-to-back-to-back Class Four wins over Happy Valley’s 1,200m course, Son Pak Fu settled fifth under his regular rider, Jerry Chau Chun-lok, from barrier four.

Mindful of the midweek meeting’s off-rail pattern, Chau was looking to get off the fence as the field rounded the home turn. A suitable gap presented itself, Chau angled Son Pak Fu towards the centre of the track and the four-year-old Fighting Sun gelding did the rest, breezing past Telecom Spirit and winning by a space eased down.

The manner of Son Pak Fu’s fourth Happy Valley victory shocked Yung, who attributed his young sprinter’s form turnaround to a combination of greater maturity and a subtle gear change.

“He keeps improving. He’s better than I thought. I’m surprised he won so easy,” said Yung, for whom Son Fak Pu was his 25th winner this season.

“When he came to Hong Kong, he was quite green and had a lot to learn. Last season, he hanged badly. Since he’s gained more experience and I changed his gear to one-eyed blinkers, he’s improved a lot.”

Elsewhere on the card, Caspar Fownes, David Hayes, Derek Leung Ka-chun and Karis Teetan posted doubles.

No trainer has saddled as many Happy Valley winners this term as Fownes after he celebrated a race-to-race double with Invincible Missile and Ace Talent.

A Class Four winner for Chris So Wai-yin on his December 2018 debut, Invincible Missile made it two successes from two starts in the grade when he won the Class Four Gwangju Handicap (1,650m).

“Gate two was a bit of an advantage,” Fownes said of Hugh Bowman-steered seven-year-old miler Invincible Missile. “He’s been racing quite well. He just needed a bit of rating relief. He got into the right class.”

Unplaced on each of his first nine appearances, Ace Talent went from zero to hero to win the Class Four Daegu Handicap (1,000m) under Alexis Badel.

“He drew gate 12 the other night. He jumped really well, but it just didn’t work out. From gate five, Alexis has given him a good ride, and he’s just fallen in. It’s job done,” Fownes said of Ace Talent.

Class Four Daejeon Handicap (1,200m) second section victor Snowalot and Class Three Busan Handicap (1,000m) winner Harmony N Blessed supplied Hayes with his Happy Valley double, with the latter completing Leung’s multiple following his success aboard To Infinity in the Class Five Ulsan Handicap (1,650m).

The last event of the night, the Class Two Seoul Handicap (1,200m), went to one of the rising stars of Hong Kong’s sprint division, Howdeepisyourlove, who did what so few runners could and made ground on the inside to score by a neck from Rock Ya Heart.

Howdeepisyourlove was the second leg of Teetan’s double. The Mauritian jockey won the Daejeon Handicap’s first section on Telecom Speed.

Tony Cruz quinellaed the feature race on the programme, the Class Three Korea Racing Authority Trophy (1,800m), with La City Blanche defeating his stablemate, Majestic Victory, by a neck.
