Nicole Castrale, a tournament invitee, and Jessica Korda, a former No. I in the amateur game who is playing in what is only her second event as a professional, gave an afternoon clinic to youngsters involved in HSBC's Youth Golf Programme in Singapore. To no-one's great surprise, the children, aged eight and over, were straining at the leash to see two such superstars in action.
They looked on in awe as the professionals demonstrated an assortment of shots, while the professionals appeared no less taken with what they then saw from the youngsters. At the end of the hour-long session, they sent them on their way with bags of encouragement and a handful of tips.
"It was a huge experience," said one of the participants on her way back to the clubhouse. "I only wish it could have lasted for longer."
Earlier in the day, Christabel Goh, the Singaporean professional who has qualified to play in the HSBC Women's Champions, had talked animatedly of difference which HSBC were making on the junior front on the island. In her day, her father had to seek permission for her to go out on the course. Now, as she says, juniors are playing all the time.
The Castrale - Korda clinic was not the only such session on the go...
Earlier, Paula Creamer, the so-called Pink Panther, took to a pink-ribbon bedecked practice ground with a handful of ladies whom she schooled in the art of chipping and putting. The lesson over, she presided over a competition involving three of her charges taking on three others in a little contest.
Creamer, who won last year's US Open only four months after coming back from surgery on her left thumb, has often said that it was only when she missed her first cut on the LPGA Tour - in 2005 - that she got to grips with the importance of the short game.
Her coach, David Whelan, had told her to take six balls just off the edge of the practice putting green and to try and get each of them up and down at her first attempt. Though Creamer did not anticipate that she could do it at the first time of asking, she insisted that it would take three attempts at most.
In the event, it took her 57 attempts and a total of three hours.
Three years later, there were times when she could complete the exercise in ten minutes, but plenty of others when it could stretch across an entire morning.
Stella Taylor, who was at today's Creamer session, explained why she and others had got together to form a Singapore Ladies' Pink Golfers Club.
"The Pink Golfers," she said, "is a group of ladies looking to develop our golf. Our motto is to play well, to look good and to live well. We believe that Paula Creamer embodies all these things and is simultaneously a real inspiration.
"What we learned from her today is that confidence is all-important and that you have to practise all the time if you want to improve."
Creamer, for her part, thanked TaylorMade for their involvement and said how much it meant "to come to a country which values women's golf."
