Ralph Beckett's Participle is the clear pick on form and has an outstanding pedigree which makes her of particular interest in the Betfred 'Play Fred's £5 Million' Maiden Stakes at Haydock on Friday.
By Frankel out of the Bated Breath mare Present Tense, Participle is a half-sister to Macduff, who ran in last year's Derby.
On her only outing last year, Participle pushed Ed Walker's Qilin Queen to a nose at Salisbury in August with Aidan O'Brien's Butterfly Wings back in third.
Qilin Queen has since finished second to French Derby-bound Luther, third to the smart-looking Falakeyah and won a Listed race at Newbury to book her ticket for the Oaks.
Participle was declared to run last week but has been withdrawn with a vet's certificate, which suggests her absence has not been down to anything major.
Alan King's Kurakka might be able to defy an opening mark of 82 in the Betfred 'The Classic Bookmaker' Handicap.
Two decent efforts at Kempton last year behind smart types in Aurel and Bowmark set him up nicely to get off the mark first time out this year at Chelmsford.
The step up in trip to 2000m clearly suited and the third has come out and run a nice race since, so the form has a solid look to it.
For many years Simon Walker has been the go-to man in amateur riders' races and his booking for the Kevin Ryan-trained Ribble River strengthens his claims.
Walker has been the best in his sphere for some time now, yet he has only ever had three rides for Ryan, without success.
Ribble River ended last season with wins at Carlisle and Hamilton and made a perfectly satisfactory reappearance when third at Pontefract.
The four-year-old has leading claims in the Betfred 'Bet Builder' Amateur Jockeys' Handicap.
Tim Easterby has made an impressive start to the season with his two-year-olds and Under The Radar might be able to give weight all round in the Ruben & Eviee 0Harker EBF Restricted Novice Stakes.
A cheap buy at 14,000 guineas, he finished fourth of eight on debut before winning at Thirsk and shaped well enough in a red-hot race at York last time out with the winner, Ballistic Missile, Royal Ascot-bound.
None of his rivals who have run have achieved anywhere near the same level of form and he can put that experience to good use.
Sea Of Kings finally gets the chance to back up his very promising debut effort when he goes to Chepstow for the Pricing By Real Bookmakers At Dragonbet Maiden Stakes.
He was bought privately by Wathnan Racing after finishing a fine second to Munsif at Nottingham in early April.
The winner has defied a penalty since and this brother to Sea Of Class, who won an Irish Oaks, could set himself up for Ascot with a win.
Tina Jackson's Cheerleader was a surprise winner at Redcar last week but there appeared to be little fluke about it.
Sent off at 66-1 having left Karl Burke, she travelled like the best horse and duly put the race to bed.
She has been hit with a 6lb penalty but meets mostly out of form rivals so could well follow up. - Press Association
