LAUSANNE, Switzerland – Tamara Korpatsch upset WTA World No.69 Anastasia Potapova, 6-3, 3-6, 6-1 to move into the quarterfinals of the Lausanne Ladies Open.
Having reached the last eight of the Swiss Open in Gstaad two years ago, the German had already defeated No.8 seed Eugenie Bouchard this week and once again showed her capabilities on the dirt to eliminate the up-and-coming Russian, who had come through qualifying to reach the main draw.
She controlled the majority of this near-two-hour affair, deservedly taking the first set before her opponent hit a purple patch early in the second to draw level. The third all went the way of the 24-year-old, however.
Korpatsch, the WTA World No.142, opened the match confidently, winning four of the first five games and manufacturing a break point in the one that got away, hitting a string of impressive winners in the process.
It was only when 4-1 down in the opening set that Potapova responded, but the 18-year-old missed two presentable opportunities to break, notably firing a simple forehand wide.
By contrast, Korpatsch sealed the first set with a brilliant crosscourt winner.
The Russian became more aggressive in the second, hitting with better depth and pushing up towards the baseline. She bludgeoned her way to a break early in the set, and though she came under significant pressure in her following service game was able to defend her position.
A second break rapidly followed and proved necessary as Korpatsch raised her level towards the end of the set, even earning two points to draw back on serve. Potapova got over the line but did so in a thoroughly unconvincing manner.
After a set that saw break points in all but one game, Korpatsch scored a comfortable hold to maintain her momentum then set about winning the subsequent four games as she stepped up a gear and showed a lovely balance between touch and power against an increasingly confused opponent.
The teenager eventually got on the board in the final set by holding serve, but the day was to belong to her opponent, who will now face the winner of Jil Teichmann and Simona Waltert as she bids for a place in the semifinals.
