A couple of top drawer Group 2 contests dominate Sunday's (9 April) action at Sha Tin but away from the Chairman's Trophy and Sprint Cup there is some attention grabbing action.

The Class 2 Jinbao Street Handicap (2200m), race nine of 10 on the day, features a clutch of smart four-year-olds with something to prove following defeats in last month's BMW Hong Kong Derby (2000m).

While Derby victor Rapper Dragon will go up against established Group 1 seniors in the Chairman's Trophy at a mile, those he vanquished will step up to 2200m as they attempt to prove their merit with the G3 Queen Mother Memorial Cup (2400m), G1 Audemars Piguet QEII Cup (2000m) and G1 Standard Chartered Champions & Chater Cup (2400m) on the horizon.

Beauty Generation (128lb), Helene Charisma (125lb) and Eagle Way (125lb) finished third, fifth and sixth, respectively, behind their John Moore-trained stablemate in the Derby and will take their places in the 14-runner contest.

Beauty Generation's one win from five Hong Kong starts came in a mile Class 2 back in January, but jockey Zac Purton believes the extra distance might be favourable. The Road To Rock gelding has attempted a trip beyond 2000m only once before, when fourth in the G1 BMW (2400m) at Rosehill a little more than a year ago.

"He ran as well as he could in the Derby, the first two home are just different class, that's all," Purton said. "With the longer races coming up further down the track it's a good chance to run over a distance, use it as a stepping stone and see how he handles it.

"He seems to run the same race at any distance you run him at," he continued. "He's never been one that would run right through the line; what you see at the furlong is what you get at the finish. He's not running home in cracking sectionals the last furlong - he gets himself into that position but he can't seem to put them away."

The former champion jockey is of the opinion that the consistent four-year-old's run pattern is evidence that there might be improvement ahead.

"I think that inability to put them away is just a reflection of where he is physically and mentally - I think as he matures and strengthens up a little bit, hopefully he'll finish off his races a little bit better. I still think the horse is a little bit untapped. I don't think we've seen the best of him yet," he said.

"Every time I work him he just seems to get a little bit better, so I don't believe he's the finished product yet."
