Silvestre de Sousa continued his magnificent run of form with an incredible six-timer on Friday.
Champion jockey in 2015, the Brazilian led this year's title race by 11 winners ahead of the day's action after riding four winners at Yarmouth on Wednesday and one at Newbury on Thursday.
He got the afternoon off to a flyer at Sandown aboard the Mark Johnston-trained Branscombe (8-1) in the five-furlong novice event and swiftly doubled up for the Middleham handler on Falmouth Light (5-1) in the seven-furlong maiden.
De Sousa brought up his hat-trick as Roger Varian's 7-4 favourite Call Me Grumpy scooted clear in the seven-furlong handicap and it was similarly easy work aboard his stablemate Shargiah, who comfortably justified 11-8 favouritism in the nine-furlong handicap.
He looked to have a big chance of continuing his domination of the card in the one-mile fillies' handicap aboard 6-4 joint-favourite Tirania, but she was beaten a neck by market rival Time Chaser, ridden by James Doyle.
De Sousa sat out the penultimate race of the afternoon, which went to 7-1 shot Jupiter Light, but book ended the card aboard the Johnston-trained Dominating (7-4 favourite) in the last.
He headed to Goodwood for four rides in the evening and managed to add to his tally aboard Brian Meehan's 8-1 shot I'vegotthepower in the one-mile handicap.
De Sousa has five booked rides at York and two at Lingfield on a busy Saturday.
