Angelique Kerber felt the same old, rhythm as last year at the Volvo Car Open. Venus Williams wished that she did, too, instead of bowing out of the tournament Thursday in Charleston, S.C.
The top-seeded Kerber, the defending champion, advanced to the quarterfinals with a 6-2, 6-3 victory over Slovakia’s Kristina Kucova. Williams looked like she would join the reigning Australian Open champion, up 2-1 in the third set of her match. But instead, Yulia Putintseva won five of the final seven games to oust the 35-year-old American, 7-6 (5), 2-6, 6-4.
Kerber will face Irina-Camelia Begu on Friday while Putintseva will face fifth-seeded Sara Errani, a 6-4, 7-6 (5) winner over No. 10 seed Samatha Stosur. Begu topped Puerto Rico’s Monica Puig, 6-1, 2-6, 7-6 (4).
No. 7 seed Sloane Stephens, the lone American left, will take on 14th-seeded Daria Kasatkina of Russia. Stephens defeated 12th-seeded Daria Gavrilova of Australia, 6-4, 6-3 while Kasatkina topped U.S. wild-card entrant Louisa Chirico, 6-0, 6-4.
The last match Friday pits Russian qualifier Elena Vesnina against Laura Siegemund of Germany. Vesnina beat Lourdes Dominguez Lino of Spain, 6-1, 6-3 while Siegemund topped Mirijana Lucic-Baroni of Croatia 7-5, 6-2.
Kerber continued to gain confidence in the season’s first clay-court tournament. She needed a third-set tiebreaker to win her opening match on Tuesday night. This time, Kerber relied on her steady groundstrokes and relentless returns to knock off Kucova.
Kerber broke her opponents’ serve seven times and said she began to the feel the excitement here she did a year ago when she captured the title.
“I think the feeling is coming back like I had last year because right now, I’m feeling much better on clay again,” she said.
Williams also overcame some issues after dropping a first-set tiebreaker and rallying to move in front of Putintseva, who was 0-3 all-time against the U.S. great.
The 21-year-old Putintseva, though, dug in to pull off the upset.
Putintseva fought through five deuces — three of them with Williams a point away from going up 3-1 — to tie the third set and then run out to a 4-2 lead. After Williams rallied back a final time and the large, stadium court crowd cheering her on, Putintseva bore down to close out the victory and beat a second former Volvo champion in as many matches. Putintseva defeated 2009 winner Sabine Lisicki on Wednesday before her win over Williams, the 2004 champion here.
Putintseva jumped around after the victory, pumping her fists and celebrating. Ranked 61st in the world, she entered the match with a 3-14 record all-time against players in the top 20.
Williams’ steady serve unraveled down the stretch: She made seven of her 11 double faults in the third set.
Sock advances to quarterfinals
Defending champion Jack Sock beat Australia’s Matthew Barton, 6-2, 7-6 (5) on Thursday to reach the quarterfinals in the U.S. Men’s Clay Court Championship.
The fourth-seeded American won last year at River Oaks for his first ATP Tour title. He will face seventh-seeded Marcos Baghdatis of Cyprus, a 6-4, 6-3 winner over Spain’s Fernando Verdasco.
Third-seeded Feliciano Lopez of Spain also advanced, beating Lukas Lacko of Slovakia, 7-6 (4), 6-1. Lopez will face Tim Smyczek, a 6-2, 6-4 winner over Donald Young in an all-American match.
Fellow Americans John Isner and Sam Querrey reached the quarterfinals Wednesday. The top-seeded Isner will face South Korea’s Chung Hyeon, and the fifth-seeded Querrey will play Argentina’s Juan Monaco.
