THIS season's crop of griffins have continued the trend of recent seasons with a good number of them emerging as potential stars. There has already been Debonair, Wonderful Moment, the Winning Chance and Flirting Dancer. And tomorrow's griffin event should be one of the most fascinating run so far this season. Chris Cheung sends out Top Glory, who did his final piece of work on Wednesday rather than yesterday and that is always a good sign. Any horses asked to work seriously on a Wednesday or a Sunday are ones to jot down and follow - fewer reporters turn out on those days. But Top Glory's last two trials were not missed - and the more recent trial was very impressive. He is improving all the time and looks the type who will be winning good races even if tomorrow's event comes a little too early in his preparation to make him a good thing. Whatever he does tomorrow, he will be hugely better for the experience. Backing griffins first time out is a dangerous game, but it should be worth keeping Top Glory in quinella bets on the opening event. Ivan Allan's Mighty Mighty has come back working well after a spell on the sidelines with sore shins. He impressed in his work on Tuesday morning and was out again yesterday. He looks ready to improve upon his debut effort down the straight 1,000 metres. California Gold was strongly fancied the day that Go Go beat Flirting Dancer and is now with Brian Kan Ping-chee after running that day from David Oughton's yard. He worked well with Sound Print yesterday and there is no doubt that he is another with heaps of potential. For one moment there was a worry that he was starting to go the wrong way in his attitude, though. He developed a tendency to bolt in his work in the mornings and it is worth remembering that not even iron man Mick Kinane could hold him in his race. If he can be settled by Felix Coetzee tomorrow and by trainer Kan in his work then this is another horse who could go a long way. Then there is form horse Magic Joy, who was a good second to Winning Chance, beating off some stiff competition for the quinella spot down the straight 1,000 metres last time out. Kenny Kam's Winning Wave also has a fair amount of scope, showing good speed in the mornings. He went as well as he has gone yesterday. In other work yesterday, Lucky Sound went well under Basil Marcus in preparation for the fourth where he will be strongly challenged by Sky High. Neither horse had any luck in running last time out but both continue to impress at the track. The fifth saw a pleasing piece from the improving Cruise Missile while Best Runner looked very well in his coat when out on Tuesday morning, the best he has looked all season. Manor Lord sprinted up impressively for the seventh for which Heavily Armed, Geoff Lane's newcomer, is all the talk.
