Volkswacht Bodensee - Pegula powers into WTA Finals last four

Pegula, the oldest player in the field at 29, had already clinched her spot in Saturday's semi-finals and Sakkari was already out of contention before the match on the Mexican outdoor hardcourts.

Pegula, who went winless last year in her WTA Finals debut, seized control early, leading 4-1 in the opening set on the way to a dominant victory in difficult, windy conditions.

She took full advantage of 35 unforced errors from Greece's Sakkari, including eight double faults, Pegula reaching the last four without dropping a set.

Pegula was pleased to keep things rolling in the unfavorable conditions, saying she tried to play to the middle of the court and keep down mistakes.

"It's so tough to play in these conditions," she told Tennis Channel. "You're trying to do your best and as soon as you get some momentum, you still feel like you could lose it.

"If you just stop moving your feet for one second, you get one unlucky shot. So you're very on edge.

"It was crazy out there today," she said.

Pegula's brisk run through her group matches included an upset of Aryna Sabalenka, the world number one who faced a do-or-die clash with fourth-ranked Elena Rybakina for the second semi-final berth from the group.

The two met in January in the Australian Open final, where Sabalenka triumphed in three sets for her first major title.

She had pushed her career record of Rybakina to 4-0 before the 24-year-old from Kazakhstan won two straight -- in the Indian Wells final in March and in the quarter-finals at Beijing.

Sabalenka, who is one of several players who have complained about the condition of the court at this week's tournament, is not only gunning for the prestigious title.

She's also aiming to take the year-end number one ranking, which could still be claimed by Poland's reigning French Open champion Iga Swiatek.
