Ryan Moore is as short as 1-10 with Coral to be crowned champion jockey for the first time following the news that Jamie Spencer has been hit with a 16-day suspension.
The title holder trailed Moore by 12 winners at the start of racing yesterday, and bookmakers have acted accordingly in light of developments at Shaftesbury Avenue.
"Although Jamie Spencer has vowed to fight on, and there will be plenty of racing left once he has served the suspension, the odds suggest Ryan Moore has one hand on the title," said Coral's David Stevens.
Spencer can be backed at 6-1 to retain the title he won for the first time last season.
The ban rules Spencer out of two of the most prestigious fixtures on the racing calendar, namely King George VI and Queen Elizabeth Diamond Stakes day at Ascot and also the whole of Glorious Goodwood.
Spencer was found guilty of careless riding by the disciplinary panel of the Horseracing Regulatory Authority.
He is banned from July 28 to August 9 inclusive with the three other days deferred until October.
The panel inquired as to whether Spencer committed a breach of Rule 153 on Garafena, runner-up in the Kleinwort Benson Maiden Stakes at Newmarket last Wednesday.
The matter was referred to the HRA under the 'tottingup' procedure following an adjourned inquiry at New-market on Thursday because Spencer had been suspended from riding for 20 days for interference within the previous 12 months.
He was handed an automatic 14-day ban plus an extra two days for the Garafena offence.
"He's known it's been coming and it's not a great surprise," said the Irish rider's agent Andrew Sheret. "I don't know what he's going to do with himself while he's off but I do know that he'll still be giving it his all when he gets back."
To spice up its market, bet365 have decided to ask punters to predict how far either rider will win the title by.
Moore is 1-6 to take the title following the ban with Spencer a 7-2 shot, but the former can be backed at 11-2 with the Stoke-based outfit to win the championship by 26 or more.
"Many punters will feel that today's news is the final nail in the coffin of this season's champion Flat jockey betting as Ryan Moore is now the red-hot favourite, but hopefully this market may breathe some life back into it," said bet365 spokesman George Primarolo.
"It remains to be seen just how much Moore can take advantage of his enforced absence. I would imagine he would want to be at least 20 ahead of Spencer by the time his suspension is up."
Also in front of the HRA's disciplinary panel was Eddie Ahern but he also left with some bad news.
The jockey was appealing against a decision handed out by the Newmarket stewards last Friday that he had been guilty of careless riding on Easy Lover, unplaced behind Eddie Jock in the Community Union For Safer Betting Shops Nursery.
However, the panel ruled in favour of the stewards and Ahern will be out of action on July 25-26, although he was given his £500 deposit back. n Tony McCoy and Paul O'Neill were handed two-day suspensions by the stewards at Cartmel after a thrilling finish to the Weatherbys Bank Handicap Chase yesterday. Both were found guilty of using their whips with excessive frequency without giving their mounts, Be The Tops and Mocharamor respectively, time to respond.
The jockeys will miss July 31 and August 1.
