Berliner Tageblatt - Swiatek off the mark with WTA Finals opening win

Polish star Swiatek looked out of sorts in an error-strewn first set in which she trailed 2-5 before roaring back to clinch a 7-6 (7/3), 6-0 victory.

The 22-year-old four-time Grand Slam champion from Warsaw is bidding to reclaim her world number one tennis ranking from Aryna Sabalenka at this week's season-ending finals in Mexico.

However that goal looked unlikely during a nervy opening from Swiatek, who was broken in her first service game before seventh seed Vondrousova held for a 2-0 lead.

Swiatek managed to claw the break back in the fourth game to square the first set at 2-2 but then fell to pieces as Vondrousova broke for a 3-2 lead and then held to go 4-2 up.

Another shaky service game from Swiatek ended in a break of serve to leave Vondrousova in the driving seat at 5-2.

But Vondrousova's game collapsed thereafter, and Swiatek broke back twice in quick succession to level the set at 5-5 before holding for 6-5.

Although Vondrousova steadied the ship to hold serve and set up a tie-break, it was only a temporary reprieve.

Swiatek quickly took control of the breaker and clinched the set when Vondrousova double-faulted.

Vondrousova's service game went into meltdown in the second set, with Swiatek breaking her three times in a row.

Another Vondrousova double-fault left Swiatek 5-0 up, and the Pole sealed victory on her serve in the final game.
