Melbourne ace Steven King last night bowed out of Hong Kong on a victorious note when bringing home potential top-notcher Electronic Unicorn a classy winner of the Yan Oi Tong Cup at Sha Tin. Despite having to steady and lose a length at the top of the straight in this Classes One and Two 1,800-metre contest, King was able to come cruising through on the progressive son of Housebuster to post a dominant 2.5-length success on the four-year-old. The outsider Excel Kid held the improving Trader Joe for second, with Telecom Chief showing he's on the way back by running fourth. 'It's just the best way to go,' said King, who will resume his freelance career in Australia with Group One rides this weekend. 'Leaving at this time was the right decision to make for my family. I've had a great five years here and this one (Electronic Unicorn) could be a smart horse. 'I've always thought he was a good horse from when I sat on him as a griffin. He hasn't stopped improving yet. 'It's particularly pleasing to win as the owners could have opted for someone else. 'They've got a talented horse here and need someone who can commit to him. But they stuck by me and we've done the job.' King was given a rousing send-off by the crowd as he and Electronic Unicorn paraded before the grandstands. King had high hopes of a back-to-back double for himself and his retaining trainer, Ricky Yiu Poon-fie, with Kiwi Star in the final event. But they found the David Hill-trained Peak Power three-quarters of a length too good, despite pulling 3.25 lengths clear of the third Koh-I-Nor. According to Hill, Peak Power is a three-parts brother to his legendary River Verdon. 'He's already looking for farther than this mile and I was worried the race might come a bit quickly for him after his unlucky effort last time. 'I entered him to get on the reserve list with a view to an 1,800-metre event coming up. 'But he got in and he's won, so it doesn't matter. He could be a handy staying type, but like all mine has needed a bit of time.' Irishman Jimmy Quinn celebrated gaining an extension to his Club Jockey licence until the end of the season when taking the opening race on the Andy Leung Ting-wah-trained Silver Collector and then powering home John Moore's Top Class a head in front of Express Lot in the fifth. Quinn has now ridden seven winners in a prolific stint since his headline split with retaining trainer Brian Kan Ping-chee. 'I've been working hard, but it's more than worth it the way the results have been coming. But I'm not taking anything for granted,' said Quinn. 'I'm just grateful to the Club for giving me the opportunity.' Smiling Stephen Baster made it three wins in three meetings when scrambling home by a short head on Iron Tycoon in the second event. Trainer Alex Wong Siu-tan had poured the work into the four-year-old and for once this son of Our Poetic Prince managed to get, and keep, his head in front. Wong went on to complete a double when the dirt-loving Bold N'Power held off the late flourish of another dirt specialist, Flowers Treasure, in the third. Bold N'Power was breaking a luckless losing streak for Club jockey David Harrison, who has the top ride on Derby runner-up Housemaster in Sunday's Gold Cup. Concert Star looked a youngster going places when galloping them into submission in the fourth under Felix Coetzee. Trainer Tony Cruz has kept him to Happy Valley and the dirt as this impressive son of Dehere didn't have the best of legs earlier in his career. There was a bumper $62 million Triple Trio dividend declared to a $10 stake last night. Two $5 tickets and three winners with a $2 stake shared in the pool. The $36.9 million jackpot carried forward led to total sales of $115.7 million.
