Midweek racing is back at Sha Tin next Wednesday with the Jockey Club holding the second mixed meeting of the season. And punters should keep the promising Good Relation in mind if his connections decide to accept for the Class Two Kam Tin Handicap over 1,600 metres. The well-bred four-year-old has only had the two runs in Hong Kong but really impressed last time out when ridden by Jason Weaver over 1,400 metres at Sha Tin. He rocketed home from the rear of the field to finish a close-up fourth behind Authorised and the extra 200 metres on Wednesday night looks made to order. His Australian form appeared mediocre with his only success coming in a lowly maiden at the provincial Hawkesbury track, but he has obviously blossomed in Hong Kong under Wiley Wong's care. Yesterday, he was not asked to make any time over 800 metres but he looked a picture of health and ready to produce his best when next sent to the gates. Ivan Allan has Charming Success down to contest one of the sprints on the all-weather track and the youngster has been vastly improved by two runs. He showed his ability to handle the dirt when finishing second to Just Perfect last time out and he should prove hard to beat if he runs. With Triumphant Star for company, the pair strode over 800 metres and both were doing it kindly on the line as they stopped the clock in 52.4 seconds. Triumphant Star is an unraced son of Naturalism, and the Australian-bred two-year-old had trialled well last Tuesday down the straight. He may need a couple of runs to reach his top but he does look to have plenty of ability. Lawrie Fownes has finally been able to find a 2,000-metre race for Mighty Combination on Wednesday and the gelding should play a big part in the finish of his event. He has been finding the tempo of shorter races against him but has held his condition well and impressed running 800 metres in 51.0 seconds yesterday. Solidarity is another with a strong chance in his event. After a dry spell, David Hayes' horses are starting to blossom again and Solidarity should be winning in the near future. He had been a little disappointing before finally showing something last time out when a close-up fourth to Sunny Graham on the all-weather. And his work has picked up noticeably, which showed yesterday as he dashed the last 400 metres of his gallop in strong fashion, running 24.2 for the section. Of those who worked in preparation for today's Centenary Cup programme, Keen Talent and Winning Touch impressed as they sprinted up 400 metres of the straight - they should go close in their respective races. There were two trials held on the dirt with Nazakat's Joy taking a moderate first heat and Fred doing it well to take the second. Fred has been freshened up since a poor effort at his previous start and the handy sprinter does look a lot better. Keep On Going and Footprints went well in behind Fred in the second batch.
