NEWCOMER Glenn Boss kept his name to the fore with a well-timed, last-gasp win on bottomweight Twin Dragons (9-1) in the distance event on yesterday's Sha Tin card. Twin Dragons, who had made up ground in a Happy Valley run last time, did not look that well-placed at the home turn in the Class Two, 2,000-metre event, where Fat Choy Together (3-1) jumped favourite. But Boss angled him out from behind a bunch, put Twin Dragons into a widening gap and then wound him up for his final rally, which saw the five-year-old touch off the impeccably ridden Sensible Choice (7-1) by a neck. French ace Eric Legrix looked home on Sensible Choice and had done everything right. But the 19-pound weight swing in favour of the winner was clearly crucial. Sensible Choice looked to have a winning break on the 14-runner field when Legrix had him two lengths clear at the 150-metre mark. But Twin Dragons, under no weight and a strong ride, inched closer as it became obvious there was nothing else in the field going to get near Sensible Choice. In a flying finish Twin Dragons got up, with weakening favourite Fat Choy Together holding on for third ahead of Sky Walker (15-1). Fat Choy Together was on the pace set by Winner's Special, and Anton Marcus kicked for home at the top of the straight. Fat Choy Together responded gamely but they were in front on sufferance until Sensible Choice swooped. Musical Insight was the flop of the race. Although ground conditions were no worse than barely yielding, the Irish import gave no sort of a sight under Danny Lee after what had seemed an excellent effort at his previous start. Claimer Richard K. M. So broke a losing streak of more than 100 rides when bottomweight Be A Friend (36-1) made virtually all in the 1,800-metre eighth event. The Lawrie Fownes-trained galloper benefited hugely by having only 111 pounds on his back, and he was able to hold off the late challenges of topweight Most Delighted (5-1) and 90-1 chance Win Label. Most Delighted looked set to collar Be A Friend about 100 metres out, but again the weight swing was decisive. The Marcus-ridden Most Delighted had to concede 20 pounds to the winner.
