BOOKMAKERS left Royal Windsor Racecourse with empty satchels after five winning favourites rewarded punters who braved the heavy showers on Monday.

Former champion Ryan Moore rode his second hat-trick of the season at the track, including one for his father and trainer Gary Moore, while Ocean Tempest won the feature Listed Royal Windsor Stakes.

Ocean Tempest was a surprise winner of the Lincoln Handicap at Doncaster back in March, and then backed that up with victory in the Listed Paradise Stakes at Ascot last month.

The John Ryan-trained five-year-old had been risen 13-pounds in the handicap for those successes but still had enough in hand to see off old foes Fencing and Fire Ship.

Ocean Tempest (5-4 favourite) led his four rivals turning into the home straight and, having been driven by jockey Adam Kirby, stayed on well to hold runner-up Fencing (3-1) by three quarters of a length.

Cajoling (33-1) was a shock winner of the opening maiden fillies’ stakes for Berkshire-based trainer Jonathan Portman - his first success at Royal Windsor since 2011.

The rank outsider of the six-strong field was given a reminder to take the lead by jockey Richard Kingscote halfway down the straight, but only had to be pushed clear to beat second-placed Russain Heroine (11-10 favourite) by two and three quarter lengths.

Moore landed the following maiden stakes over a mile and a quarter aboard Purple Spectrum (15-8 favourite), despite dropping his whip inside the final furlong.

Purple Spectrum had to be urged along with a half-mile still to run and only got to the leaders in the closing stages, but the pair found enough to assert near the finish and win in the colours of Her Majesty The Queen.

Lamorak (20-1) was three quarters of a length back in second position with Grand Meister (5-1) keeping on at the same pace to take third, beaten two lengths.

Moore doubled his tally soon after aboard Stampede, who was justifying an entry in The Derby at Epsom Downs on June 7 (4pm).

Stampede (2-1 favourite) was held up in the last pair before closing on the leaders and taking the lead just inside the final furlong.

The son of 2002 Derby hero High Chaparral only had to be pushed along firmly to assert and readily beat runner-up New Colours (66-1) by a length and a quarter.

Moore completed his hat-trick aboard Lady Marl, trained by his father Gary Moore, in a competitive handicap over the sharp mile at Royal Windsor.

Lady Marl (5-1 joint favourite) took a keen hold early on but stayed on well to draw clear inside the final furlong and have two and a quarter lengths in hand of the field at the winning post.

Jersey Brown (7-1) took second position inside the final furlong from Division Belle (10-1) back in third, beaten three and three quarter lengths.

The concluding handicap over a mile and a half went to Der Meister (6-4 favourite) for trainer Andrew Balding and rising star Oisin Murphy - the claiming jockey’s 19th winner of the campaign.

Der Meister was slowly into stride and the first of the five runners to be hard-ridden, but a sustained effort saw the gelding hold runner-up Template (9-2) by half a length.

Racing returns to Royal Windsor on Monday where a six-race evening meeting begins at 6.05pm and features a novice stakes, traditionally used as a trial race for Royal Ascot.
