The first half of a Douglas Whyte double showed the 13-time champion's name still carries plenty of cache as Benno Yung Tin-pang held promising sprinter Super Talent back a week, forgoing a possible feature race win, for the South African to ride.

Super Talent could have lined up as one of the leading hopes in last weekend's Griffin Trophy, but instead won easily as odds-on favourite four days later in a Class Four with Whyte aboard, giving the jockey a double after he won on Charity Joy earlier in the day.

Yung explained that skipping the Griffin Trophy wasn't simply about keeping his three-year-old at 1,200m and avoiding tough opposition, but making sure he had a top rider on board after a series of near misses.

"I just couldn't find a jockey for him last weekend, we wanted one of the top guys," Yung said. "We wanted Douglas but he already had a ride [runner-up Sky Hero] so we waited."

From gate three against a weak field, Whyte made sure Super Talent broke his maiden and believes more is in store for the HK$3 million 2013 international sale purchase.

"He is doing it on raw ability at the moment," the jockey said. "I think he is going to want a mile in time and I think he has done pretty well to perform as he has at six furlongs, which I believe is way too short for him. An inch of rain on the track wouldn't hurt him either. I think there is a lot of upside to him towards the end of the season when he gets some easier conditions under foot."

The first part of Whyte's brace drew plenty of "oohs and ahhs" - and mostly disappointed ones - from the 67,984-strong crowd when Danny Shum Chap-shing's short course specialist Charity Joy brought undone what would have been the betting move of the season with a straight track win.

In a topsy-turvy final few minutes of betting, Charity Joy's odds shifted dramatically as he was usurped as favourite in the Class Two handicap and Sight Believer was slammed from as much as 5/1 to start an even-money favourite.

Charity Joy was able to overpower his more fancied rival late to win for the fourth time in 20 local starts, with the four-year-old looking like a more seasoned competitor every time he steps out.

"He has improved mentally - you can put him in a race, he will find his feet and run for you," Whyte said. "He used to be very feminine, but now he has some strength and depth to him and is a stronger individual."

All of Charity Joy's wins have been over 1,000m and Shum said the maturation process meant he may be able to stretch the son of Not a Single Doubt over further more confidently.

"I think he relaxes much more easily now and of course he has got stronger, which helps," Shum said.

"He came here having won an 880m race, and was racing very early as a two-year-old, so he still had a lot of development to come."
