Heraldo de Madrid - Gauff beats Swiatek to reach last four of WTA Finals

Swiatek, the defending champion, was in a direct battle with Aryna Sabalenka for the top spot this week but needed a win over Gauff to keep her chances alive of leapfrogging her Belarusian rival.

Gauff, 20, entered the contest having lost 11 of her 12 previous meetings with Swiatek, with the American's sole victory coming in Cincinnati last year.

But she turned the tables on Swiatek on Tuesday, defeating the second seed 6-3, 6-4 to make it two straight-sets wins from two round-robin matches in Riyadh this week.

"It feels great. I knew going into the match that despite our head-to-head I had a lot of confidence going in," said Gauff, who hit 11 double faults during the one-hour 48-minute showdown.

With the exception of the opening game of the match, Gauff had break point opportunities in every Swiatek service game in the first set.

The American third seed made her move in game seven, breaking for 4-3, and she closed out the set with a second break of serve, taking the lead in 49 minutes.

Swiatek needed six break points in a marathon third game of the second set to finally take down the Gauff serve but she couldn't consolidate her advantage.

They traded breaks again, as Gauff's double-fault tally went up to double digits and Swiatek racked up the errors.

It was Gauff who eventually steadied the ship, and sealed the victory on Swiatek's 47th unforced error of the match.

- Krejcikova eliminates Pegula -

Earlier in the day Barbora Krejcikova ended Jessica Pegula's chances of qualifying for the semi-finals, defeating the sixth-seeded American 6-3, 6-3.

A runner-up at the WTA Finals last year, Pegula suffered her second straight-sets defeat of the week and enters her final round-robin match against Swiatek on Thursday anchoring the Orange Group with zero sets won.

Eighth-seeded Krejcikova bounced back from her opening loss to Swiatek to keep her hopes of making the final four alive.

"I was fighting for every ball and I felt that I really have to play my best tennis and I was trying to be really solid and trying to put as many balls to the other side as I could," said Krejcikova, who picked up just her 20th match win of the season.

"I'm definitely proud. I had some very high parts of the season, especially winning Wimbledon, that's something indescribable. And being here in the Finals is a huge privilege. It's nice to get the win and still be part of the event."

Despite being ranked number 13 in the world, Krejcikova qualified for these WTA Finals thanks to a new rule introduced by the WTA that gave priority to a player who has won a Grand Slam this season, while maintaining a ranking between 9 and 20, over a player ranked number eight in the Race.

As the reigning Wimbledon champion, Krejcikova claimed the final qualifying spot in Riyadh over world number eight Emma Navarro.

Krejcikova squandered a 6-4, 3-0 lead against Swiatek in her opener two days ago and made sure there was no repeat scenario against Pegula on Tuesday.

The crafty Czech fired 11 aces and broke Pegula four times to wrap up the win in 69 minutes.

Both Krejcikova and Swiatek will have to wait until Thursday's matches to learn their qualification fate in Riyadh.
