QUEEN'S LOGIC makes her much-awaited reappearance in the Group 3 Fred Darling Stakes at Newbury today.

Mick Channon's unbeaten filly, installed as hot-favourite for the Sagitta 1,000 Guineas following a dazzling success in the Group 1 Cheveley Park Stakes last October, has yet to prove she stays seven furlongs let alone a mile.

But trainer Mick Channon has no worries on the stamina front: "I've never had any doubt that she'll get a mile," he reported, boosting confidence for a contest which by rights Queen's Logic (3.05) should win without so much as coming off the bridle.

Overall it's an outstanding card at the Berkshire course kicking off with the always-competitive John Porter Stakes over a mile-and-a-half.

Northern hope Zindabad has a fighting chance although he may have his hands full trying to cope with classy Mr Combustible (1.55), a thoroughly convincing winner of the Geoffrey Freer Stakes at the course in 2001.

Some pretty smart three-year-olds colts line-up for the Greenham Stakes including the stable-companion of King Of Happiness, Brigadino (3.35).

King Of Happiness put himself bang in contention for the 2,000 Guineas with a smooth-as-silk success in the Craven Stakes at Newmarket on Thursday and Brigadino is not far behind in the pecking order if recent gallops reports from Sir Michael Stoute's yard prove to be correct.

Thirsk also stage a Guineas trial kindly sponsored by Stanley Racing.

The Listed status of the £23,000 race inevitably has attracted some notable southern contenders, none more so than Sohaib from the Barry Hills stable.

He won a seven furlong maiden at Ascot in July prior to spoiling his prospects in the Champagne Stakes at Doncaster with a headstrong performance resulting in too much energy expenditure during the first five furlongs.

Thirsk is a track where because the bend comes so early it needn't be such a big problem as on a big wide-open galloping track like Doncaster, so with the proviso that Sohaib (3.20) settles just a little better he must go close.

In the Michael Foster Memorial Conditions Stakes Indian Spark (4.20) is a confident choice.

Jim Goldie's speedster ran a blinder from a diabolical draw on his comeback at Doncaster, finishing fourth under a considerate ride from Jimmy Fortune.

Fortune is on duty at Newbury leaving top-notch northern pilot Tony Culhane to do the steering in the six furlong dash.

At the lesser jump meetings Ei Ei (4.055) might be worth a sneaky each-way bet at Stratford in the Rodeney Baker Gold Cup.

Wolverhampton always has the final say on a Saturday night and the outstandingly generously handicapped Adobe (8.30) is weighted to win the Joan Chalker Memorial Handicap.
