The second week of the grass-court swing has seen Kristina Mladenovic and Elina Svitolina solidify their positions in the Top 8 of the chase to make the BNP Paribas WTA Finals Singapore presented by SC Global.
The Frenchwoman, who reached her eighth quarterfinal of 2017 in Birmingham, moves up one notch to No.5, while Svitolina's second-round showing was enough to see the Ukrainian retake the No.2 spot from Karolina Pliskova.
Neither player has previously competed in the WTA Finals in singles, though Mladenovic has twice made the final line-up in doubles - alongside Timea Babos in 2015 and with Caroline Garcia last year.
Further down, Mallorca Open champion Anastasija Sevastova has added a second career title to a year that has already seen her rack up semifinals in Dubai and Madrid and quarterfinals in Charleston and Stüttgart. The Latvian rises two places to No.13.
Australian Open semifinalist CoCo Vandeweghe's run to the Birmingham quarterfinals sees the American enter the Top 20 of the Race, climbing three to No.18, while Birmingham semifinalist Lucie Safarova ascends seven spots to No.22.
The Birmingham final was contested between players who started the week outside the Race Top 30. Finalist Ashleigh Barty, already a titlist in Kuala Lumpur in 2017, has zoomed up 16 places to land at No.25, but it's champion Petra Kvitova who made the week's largest numerical leap.
The Czech, competing in just her second tournament of the year, has soared a gigantic 252 spots to No.63.
Meanwhile, Mallorca runner-up Julia Goerges's first grass-court final sees her rise 12 places to No.35, while semifinalist Catherine Bellis becomes the youngest player in the Race Top 40 with a climb of eight to No.36.
Not content with just being one of the week's standout singles performers, Barty also joined up with fellow Australian Casey Dellacqua to take the Birmingham doubles title, and the duo have risen one spot to enter the Top 4 of the doubles Race, displacing Andrea Hlavackova and Peng Shuai.
