Buckle up, tennis fans—Friday's Charleston quarterfinal is going to be a cracker! China's teen sensation Qinwen Zheng faces off against Russia's clay-annihilating warrior Ekaterina Alexandrova in a compelling tie with all the trimmings. Zheng has been playing with Olympic-gold swagger, but Alexandrova brings with her the scars of experience from their past encounters—two victories, in other words. The Charleston clay would make this a gritty slugfest, with Zheng's power being countered by Alexandrova's ability to hang in. Will the 22-year-old wunderkind finally reverse the tables on her Russian opponent. 

Qinwen Zheng

Zheng riding into Charleston like queen for the day—following gritty 6-3, 3-6, 6-3 come-from-behind victory over Elise Mertens. The lady's on fire the last two weeks, with four wins in her last five, and that spanking Olympic gold chain around her neck to boot. She's a backcourt brawler—a big-serving (6 aces!) backcourt who can find break points (5 made). But not all grins: that 5 double faults show she does get a bit nervous when the stakes are high, and her first serve percentage (59%) might be nudged. On clay, however, she's lethal—picture her as a human backhoe, digging out 66% of break points against her. The fans are in a buzz—can she keep the pedal down on a persistent Russian who has beaten her twice already? This one's got drama written all over it.

Ekaterina Alexandrova

Alexandrova's been a bit of a mixed bag this year, but she's pulled herself together right on cue—corroding Diana Shnaider 6-2, 6-1 like it was a practice hit. Eight aces? That's her serve talking, mate—pure thunder. She's on a four-set streak, showing she can get it together when it counts, although her 51% first serve percentage's a bit dodgy—leaves the door open for a smart returner like Zheng. Her 47% first serve return record tells her she's no slouch on the other side of the court either, and 5 breaks taken from Shnaider demonstrates she can strike. Problem is, those three losses earlier this year suggest a wobbly spine when the pressure's on. Clay's her domain though—she's got the temperament for a fight. Might be a good old barney if she keeps her head.

Head to Head

These two have history, and it's all Alexandrova's way thus far—2-0. Their latest battle in Madrid 2023 was a rollercoaster: Alexandrova squeezed 7-5, 4-6, 2-6 after Zheng pushed her to the wire. Both have been close battles, with the Russian's experience telling late on. Zheng's yet to solve the code, but she's a different animal now—fitter, tougher, and seeking revenge. Alexandrova's got the mental advantage, but Charleston's slower clay could just even things out. Fireworks expected—this one could go the distance again.
