The Hong Kong Derby picture was not made a great deal clearer following the running of Mercedes-Benz Hong Kong Classic Mile on Sunday other than Sunny Sing emerging as a genuine contender. The John Moore-trained gelding again showed terrific finishing speed to gun down Hail The Storm and a crack at the $14 million Group One classic on March 26 is now under consideration. Although considered a query to run out the 2,000 metres of the Derby, the signs are certainly positive that it could well be a possibility for the son of former top British juvenile Sri Pekan. Sunny Sing's strength is his ability to quicken at the end of a race and a pointer to him getting over ground was made at his previous start over 1,400m when downing the speedy Bobo Win. On that occasion, Sunny Sing made his run early and wide but never faltered over the final 400m and was very strong at the finish. Again on Sunday, the best part of his victory was the final stages and given that he settles so well in the early stages of his races, he deserves his chance to be tried at the Derby distance. Hail The Storm lost no marks in being beaten by a race-fit horse and there is little doubt he is now ready to be stretched over a longer distance. The Caspar Fownes-trained gelding looks to be right on target for the Derby and with his ability to take a position right on the speed, he is one of the leading candidates. Willie Detroy was beaten as favourite but expect the strapping Zabeel stallion to derive great improvement from his luckless fifth. The four-year-old was looking a bit above himself prior to the event and appeared unlucky not to finish closer after being held in a pocket after turning for home. Everything about Willie Detroy suggests he will excel when he gets to the Derby distance and at this stage the Tony Cruz-trained galloper seems the one open to the most improvement. Several Derby aspirants competed at the Chinese New Year meeting on January 31 with Good Nature announcing his arrival as a genuine contender with a sound beating of Good Ba Ba and Great Achievement. The Paul O'Sullivan-trained impressive gelding has been one of the surprise packets of the season, winning five of his seven outings and having valid excuses on the two occasions he has been beaten. As impressive as Good Nature was in winning, there must be a big query on the Danske gelding running out a strong 2,000m given he over races so badly in the early stages. Even with the blinkers off last attempt, Chris Munce had a fight on his hands for the first half of the race and it is remarkable that the gelding can still show such final brilliance after expending so much energy early. Although soundly beaten, Good Ba Ba's performance indicated that is he looking for more ground and there is little doubt that 2,000m is going to suit the Lear Fan gelding perfectly.
