EXPERIENCED American rider Randy Romero exuded confidence yesterday as he talked of the major step that has made him the newest face in Hong Kong's glittering racing lineup. With the countdown to the new season well under way, Romero looks forward to flying the flag for the United States over the next nine months. He was met at Kai Tak on Saturday by his retaining trainer Gary Ng Ting-keung who has had a nervous moment or two since first attempting to line up a stable rider some months ago. Ng was left in the lurch when English rider Willie Ryan suddenly refused to make the move to Hong Kong. Romero arrived in Hong Kong within hours of riding an American winner at Saratoga. A leading rider in Florida, he said: ''It is easy to say but I am really looking forward to Hong Kong. ''It is a major change for me but I am confident that it will go very well. ''It is going to be interesting because there are sure to be many different riding styles here. ''I have a very good idea of what it will be like but I have never ridden here before. ''I am sure it will work out very well. I have been around in racing for a long time and ridden against the best.'' The 35-year-old Romero does have excellent credentials and is well regarded among European riders who have been up against him in major American races, including the Breeders' Cup series. His wife and son will join him in Hong Kong shortly. Romero is expected to undergo his medical examination tomorrow but wants to take a preliminary look at trackwork this morning.
