Paul O'Sullivan's yard is firing on all cylinders and lightly raced Dilly should snare him some more silverware in the Hong Kong Exchanges Challenge Cup (1,200m) at Happy Valley tonight, reports Racing Post Hk (www.racing.scmp.com)

O'Sullivan's renaissance has been one of the good stories of this season after the New Zealander had been through a few dire years, and he has already posted 36 winners - just two short of his tally for the past two full seasons.

Dilly (Nash Rawiller) looked a nice addition to his team, with two wins from four starts in New Zealand, even before he won his local debut in a mild surprise over the Happy Valley 1,000m.

The gelding showed ability as a juvenile but was then unbeaten in his only two starts as a three-year-old and he has carried that improvement through to Hong Kong.

Scrambling home over 1,000m first time out might have left some fans thinking that 1,200m could be an issue but Dilly was very tough at the distance in New Zealand, fighting back to win each time over this distance after looking seriously threatened.

With that in mind, tonight's distance looks even more suitable and Dilly has the early speed to take full advantage of his inside draw.

The race sets up perfectly for him, with Dashing Ceramibo and Hawthorne likely to come out of the gates running for the early lead and Dilly will have more pace than the others around him, allowing Rawiller to box seat the four-year-old.

Andreas Suborics landed a trophy race on the weekend and the Austrian looks the main danger tonight onAll Win Boy for Francis Lui Kin-wai.

All Win Boy had looked a Valley specialist until his latest run, which explains why he went out at over 100-1 when third to Eroico at Sha Tin, but he only has to bring that back to the scene of his three previous successes to see him in the finish again.
