Andrea Petkovic is back into the world's top 10 after her success in Antwerp, while Stanislas Wawrinka rose on the back of his title win in Rotterdam.
Petkovic rose to 10th in the rankings after winning the WTA Diamond Games, albeit via Carla Suarez Navarro's withdrawal from the final.
The German is a former world number nine, but injuries led to her ranking dropping - with her latest move the first time she has been in the top 10 since early 2012.
Petkovic rose two places to 10th, while the only other change to the top 10 was Czech Petra Kvitova moving above Simona Halep and into third.
Suarez Navarro was rewarded for her strong run in Belgium by jumping four spots into 13th.
Serbian Jelena Jankovic slipped out of the top 20, while Daniela Hantuchova moved up from 73rd to 47th after her title win in Thailand.
Hantuchova beat Ajla Tomljanovic in the final in Pattaya City, with the Croatian into 49th on the back of her run.
Having failed to defend his Australian Open title, Wawrinka fell to ninth in the world.
But the Swiss star's title win in Rotterdam saw him jump above the man he conquered in the final - Tomas Berdych - and into seventh.
That was the only change in the top 10, with Uruguayan Pablo Cuevas moving up nine spots to 23rd after winning the Brasil Open.
