Racing: Justifiable case for Nuclear Debate

Simon Holt of Channel 4 Racing analyses today's William Hill Trophy at York

Eastern Purple: Scored by eight lengths from Jimmy Too in well- contested Listed handicap at Haydock. May be improving fast.

Bay Prince: Must be forgiven first run this season when his saddle slipped. Successful twice last term in the space of four days, including over five furlongs here. High in the handicap.

Pool Music: No chance with the winner when beaten 11 lengths into third behind Eastern Purple at Haydock last time. Becoming difficult to place.

Atlantic Viking: Struggled to go the pace over Epsom's licketty-spit five furlongs on Derby Day but may do better over six here.

Friar Tuck: Badly drawn at Thirsk last time and better judged on an earlier second to Classy Cleo at Chester. Tail-swisher but seems genuine.

Nuclear Debate: Favourite in the race won by Magic Rainbow at Newmarket but was not best drawn and managed only fifth. Better than that form suggests and one to keep a close eye on.

Hujoom: Beat only one home in the race won by Jila at Newmarket's Guineas meeting. It remains to be seen if he has trained on. Useful last season.

Night Shot: Running well and third to Magic Rainbow at Newmarket last time. Testing conditions might stretch his stamina.

Ruzen: Highly progressive and penalised only 3lb for beating Qilin a length at Leicester after scoring at Windsor. On a hat-trick and sure to put up a bold show.

Prevalence: Early favourite for this prize on the strength of two back- to-back wins at Kempton. Plenty of scope, with a good, young trainer and likely to go close despite dropping back in distance from seven furlongs.

Marton Moss: Did not get the clearest of passages when fifth to Ho Leng here (7f) last time and seems equally effective at shorter trips. One of many in with an each-way chance.

Kayo: Could not muster enough speed when a strong-finishing seventh to Magic Rainbow at Newmarket following a close second to Ho Leng on this course (7f). May prove better suited to the longer distance.

Masha-Il: Ran well, considering he was hampered leaving the stalls, when sixth to Magic Rainbow at Newmarket. From a top stable and not to be discounted.

Magic Rainbow: Turned up at 20-1 when driven out to hold Harmonic Way in competitive 3yo 6f handicap at Newmarket last time for which he has risen 8lb in the weights. Stiffer task but clearly in top form.

The Downtown Fox: Ran too keenly when eighth to Ho Leng and Kayo on this course (7f) on last start. Needs longer trip.

Mantles Pride: Never landed a blow behind Magic Rainbow at Newmarket and will need to improve significantly on that.

Bodfari Pride: Fortunate to keep second behind Apache Red at Epsom last week having hung in closing stages. Possibly finds six furlongs on the sharp side.

Carambo: Busy filly who has twice finished second this season at Catterick and here over seven furlongs but rated an outsider for this competitive affair.

Torrent: Won at Catterick and Thirsk (from Night Shot) and then finished in midfield behind Magic Rainbow at Newmarket when not well drawn.

Prix Star: Stayed on at one pace when third to Five Of Spades at Newcastle on his return. Should strip fitter here and the booking of Royston Ffrench is interesting.

Paradable: Irish-trained filly who won a handicap at the Curragh on her latest start. Lightly raced and open to improvement.

Ryefield: Never got to the winner when second to Astrac in a small handicap at Ayr. Up in class here but should lose his maiden tag before long. Has a squeak.

Peter's Imp: A nursery winner at Newcastle last season, he made little show in the race won by Bodfari Pride at Chester on his reappearance in early may and hasn't raced since.

Rioja: Made blinding reappearance to score at Newmarket, only to perform disappointingly next time at Lingfield. Probably needs plenty of give in the ground.

Conclusion: NUCLEAR DEBATE did well from a bad draw to finish fifth to Magic Rainbow at Newmarket. Harmonic Way and Masha-Il who ran in that race are also to be respected.
