Novak Djokovic achieved a new rankings landmark, while Sania Mirza made history by moving top of the women's doubles standings.
World number one Djokovic has accumulated a total of 142 weeks atop the ATP rankings, meaning he is sixth outright on the all-time list ahead of long-time rival Rafael Nadal.
The Serbian, who has been top since July last year, is 28 weeks shy of John McEnroe in fifth and would usurp the American on November 9 if he maintains his hefty 4,310 point lead over Roger Federer.
Jack Sock's maiden ATP title at the US Men's Clay Court Championship saw him climb 10 places to 36, while Martin Klizan is up to world number 29 after winning the Grand Prix Hassan II. Daniel Gimeno-Traver, runner-up in Casablanca, climbed 27 places to world 68.
Mirza's triumph alongside Martina Hingis at the Family Circle Cup enabled the duo to take top spot in the women's doubles.
It marks a historic moment in WTA history as Mirza becomes the first Indian woman to be ranked top in the singles or doubles.
Angelique Kerber's success in the singles in Charleston moved her up two spots to 14th, while runner-up Madison Keys achieved a career-high ranking of 17.
