Anderson's rise to 7th comes courtesy of his semi-final appearance at last weekend's Madrid Open despite being knocked out by Dominic Thiem.
Thiem, who just so happened to be the tennis pro Anderson replaces in 7th, beat the South African by 6-4, 6-2 but as a result of the Austrian's returning to Madrid as a losing finalist from 2017, rather than Anderson's breakthrough performance, the Johannesburg born Anderson earned more ATP points.
2018 has proved to be a fruitful year for the South African who has reached three ATP Tour finals, with a win at the New York Open 250 series where he beat the USA's Sam Querrey.
All in all, Anderson's season has put him in a good place to make a challenge at Roland Garros for the years 2nd grand slam tournament, The French Open starting on Monday.
