Dennis Yip Chor-hong gave an insight into the untapped potential of grey sprinter Down Town late last season when he recalled watching the videos of the horse's races in Perth prior to buying him. 'He wasn't winning by much, and I couldn't say he was that impressive,' Yip (pictured) said. 'But the thing I liked was that in every race, he put his head out and tried very hard. I knew he was a racehorse.' On Sunday at Sha Tin, a very fast pace set by Classa For Ever helped us see a new side of Down Town as be bolted away to score a commanding win, his second on the trot. With Classa For Ever running the middle section (800 metres to 400m) in a blistering 21.6 seconds, the race was set up for something to finish on from further back. But Down Town was the only horse fit for the challenge. He not only took the field up to the tearaway leader but bounded past him in a couple of strides and quickly put the issue beyond doubt. This well-bred son of Scenic is from a daughter of Group One-winning sprinter Kenvain - the source of his grey colour. Down Town had eight attempts in West Australia for three wins and five minor placings - never failing to land a first three finish. He's now had six outings since joining the Yip team and his form chart is simply an upward graph, with the grey registering improvement every time. Down Town ran the 1,200m against Class Two horses in the outstanding time of 1:08.5 - a tenth of a second quicker than Town Of Fionn took to win the Chief Executive's Cup (Class One) three races earlier. Later in the afternoon, King Encosta showed substantial improvement in making it two wins from four Hong Kong starts. This son of leading stallion Encosta de Lago created a positive impression when winning in Sydney at his first attempt and since joining Tony Cruz has continued to forge ahead. Although this event was only a Class Three handicap, Cruz believes King Encosta will make it all the way to Class One and the rating increase he will get for this one will tip him over the 80-point threshold and into Class Two. The significant aspect of the win was the physical improvement King Encosta had made during the summer break. His condition was magnificent on Sunday and mounting-yard judges knew he was a winner in waiting. The other horse to come on positively during the break was Happy Giggle, an impressive winner for jockey Brett Prebble and sophomore trainer Michael Chang Chun-wai. Happy Giggle had finished second on two occasions last season behind Danny Shum Chap-shing's unbeaten sprinter, Lucky Baby, and his impressive first-up victory was a fitting endorsement for that speedy galloper.
