article: Frankie Dettori made it six winners in four days as well as three flying dismounts with a treble at Newbury on Saturday centred around a neck success on Charlie Hills-trained Greenham Stakes winner Muhaarar. Spring has sprung this week and Dettori has been bouncing higher than Tigger. In this sort of form, those who suggested his best days were well behind him will have to eat their words. Frankie Dettori leaps from his mount  after riding Muhaarar to win The AON Greenham Stakes at Newbury . Dettori rides Mr Singh to win The Al Basti Equiworld Maiden Stakes at Newbury racecourse . Thursday’s announcement that Dettori’s boss Sheik Joaan Al Thani had signed up Gregory Benoist to ride the French-based horses in his expanding string, means the 44-year-old Italian can concentrate on Britain. That means less tiring criss-crossing of the Channel for Dettori as well as having another positive spin-off – being available for rides going spare with old boss John Gosden after winter staffing rehuffles. So far, Dettori has been mopping them up. Three of the jockey’s winners – Derby prospect Golden Horn, who won the Feilden Stakes at Newmarket, Oaks candidate Star of Seville, who scored at Newbury on Friday, plus maiden winner Mr Singh on Saturday were all prepared for action by Gosden. Dettori said: ‘The Greenham was good. They went very fast and Muhaarar is a horse that needs to settle. He did and produced. ‘I don’t think I have had thee flying dismounts before so early. I have had a fantastic week. It is brilliant and being back at John’s – I have gone full circle. I am back to where I started.’ Dettori riding Muhaarar to victory in the The AON Greenham Stakes at Newbury on Saturday . Dettori had spoken of his enthusiasm for the season ahead when unveiled as the new ambassador for his home course Newmarket last week. He showed that on tricky Ayaar, 7-1 Luca Cumani-trained winner of Newbury’s Spring Cup. He now has nine winners from 29 rides, not sound seismic but it is significant compared to the last two seasons. The 2014 campaign had only 37 successes and, a truncated 2013 season when he returned from the doldrums of splitting from Godolphin and a six-month cocaine ban had him walking around like yesterday’s man.

He is no longer champion jockey material but he does look to have significant better chances of good rides in quality races. His 1,000 Guineas ride will be Richard Hannon-trained Nell Gwyn Stakes winner Osaila, who runs for Sheik Joaan, while he must pick from Hannon-trained Craven Stakes third Moheet and John Quinn’s Group One winning two-year-old The Wow Factor in the 2,000. Hannon has insisted both Greenham Stakes second and third Istidhkaar and Ivawood will join his Craven Stakes winner Kool Kompany in the 2,000 Guineas. He also might still run Tiggy Wiggy, runner-up to Ralph Beckett’s Redstart in the Fred Darling Stakes Saturday, in the 1,000 Guineas. But after a disappointing show, some bookmakers have taken her out of the ante-post betting.
