Foden (above right) won all three Welsh MX-5 Championship races - for Mk1 models of the sportscar - to continue his strong start to the season and take his tally for the year to nine.
The treble success means he has improved by six spots in the rankings and he is now five wins behind table-topper Freddie Slater.
But Foden was not the only driver to score a hat-trick at Anglesey, as Elliot Lettis also continued to dominate the CityCar Cup category in his Peugeot 107.
He has now achieved eight wins in 2023 and climbs from 27th to eighth in Autosport's winners' table.
Those were the only changes inside the top 10 this week, although Graham Moore was unfortunate not to join Lettis in surging up the order.
He won both of the Northern Ireland Sevens races at Kirkistown, which were held concurrently with the Roadsports series, but there were fewer than six starters in the Seven class and therefore his victories do not count for our rankings.
Had there been just one more driver present, Moore could have moved up to 10th place.
Another racer who did improve is Michael Cullen. The Irishman has already been successful in his Stryker and Ford Fiesta ST this year but has now been triumphant in his Mini, too, winning one of the Jack Sears Trophy races at Lydden Hill.
That was his seventh win of the year and takes him from joint 17th to 11th.
Back to drivers enjoying a triple victory, and Freddie Chiddicks was another to achieve the feat - at Silverstone in the hard-fought Caterham Seven 270R championship.
