The Hologic WTA Tour's grass-court swing kicked off last week at WTA 250 events in 's-Hertogenbosch and Nottingham, with Liudmila Samsonova and Katie Boulter taking home the silverware.

Several of this year's comeback players made strides at these events, including two former US Open champions who returned to the Top 200.

In 's-Hertogenbosch, Bianca Andreescu reached her seventh career final, and second on grass, before falling to Samsonova in a three-set thriller. Andreescu, the 2019 US Open winner, was playing her second tournament of the year after being sidelined for nine months with a stress fracture in her back. She was the lowest-ranked WTA finalist so far this year at No.228.

In her comeback event three weeks ago, Andreescu made the Roland Garros third round. The Canadian is 6-2 since returning and moves up 65 places to No.163 in the latest edition of the PIF WTA Rankings.

In Nottingham, 2021 US Open champion Emma Raducanu reached her third career semifinal -- and first since Seoul back in 2022. The Briton, who withdrew from Roland Garros to focus on the grass and hard-court swings, rises 44 places from No.209 to No.165.

Former World No.1 Naomi Osaka also delivered a promising week, taking out Elise Mertens in 's-Hertogenbosch en route to the quarterfinals. Though Osaka lost a knife-edge match against Andreescu in a third-set tiebreak, the four-time major champion climbs another 12 places from No.125 to No.113.

Other new career highs

A handful of players who were not in action last week moved up to new career-high positions:

Back in October of 2018, Katerina Siniakova rose to No.31 in the rankings -- a position that would remain her career high for more than five years. The Czech got as high as No.32 again in July 2023 but had fallen to No.90 by September.

But Siniakova finished 2023 strongly, reaching the Hong Kong final and winning her fifth career title, in Nanchang, the following week. She has put together a solid 2024, with wins against Coco Gauff in Doha and taking home the WTA 125 title in Lleida.

Siniakova moves up one place from No.31 to make her Top 30 debut at No.30.

Marta Kostyuk and Emma Navarro were also inactive last week, but inch up one place each to hit new career highs of No.16 and No.17, respectively.
