Top seeds, world No. 2 Hsieh Su-wei of Taiwan and world No. 1 Peng Shuai of China, recorded their second straight 6-1, 6-2 victory in the women’s doubles at the BNP Paribas Open on Sunday to ease into the quarter-finals, while Taiwan’s Lu Yen-hsun cruised past No. 22 seed Philipp Kohlschreiber 6-2, 6-2 to make the round-of-32 in the men’s singles.
The Taiwanese-Chinese pairing saved both break points they faced, while winning four out of eight break-point chances to overcome Russian duo Alisa Kleybanova and Anastasia Pavlyuchenkova.
Hsieh and Peng’s 80th win together set up a quarter-final encounter with seventh-seeded Australian duo Ashleigh Barty and Casey Dellacqua, who they beat in last year’s Wimbledon final.
On the other side of the draw, defending champs and second seeds Ekaterina Makarova and Elena Vesnina also had a straight-sets win.
The Russians broke in each set against German pairing Julia Goerges and Anna-Lena Groenefeld for a 6-3, 6-4 victory.
“It was a good match for us,” Makarova told the WTA Web site. “We played against a strong team. We played against them in the Olympics, so we knew [the] team a little bit. It was a difficult match, with a lot of key points. We were just a bit more lucky to win the big points, so we’re really happy to be through.”
“We have great memories from winning here last year,” Makarova said. “We’re really enjoying our time together on court. We’re just trying to stay positive, help each other and support each other.”
The Russian doubles pairing next face No. 5 seeds Cara Black of Zimbabwe and Sania Mirza of India.
Russia’s Svetlana Kuznetsova and Samantha Stosur of Australia also reached the quarter-finals on Sunday, along with Japan’s Kimiko Date-Krumm and Barbora Zahlavova Strycova of the Czech Republic.
In the men’s singles, Lu saved all three break points he faced against Germany’s Kohlschreiber, won four of his eight break-point chances and delivered six aces to seal the victory in 68 minutes and set up a round-of-32 clash with big-serving 12th seed John Isner of the US.
Isner kept the US flag flying in the men’s field with a 7-6 (7/5), 6-3 victory over former world No. 3 Nikolay Davydenko of Russia.
Isner edged Lu in two tiebreak sets in the final at Auckland in January, but since winning that title, the American has been slowed by an ankle injury.
In other second-round ties, Novak Djokovic made it safely into the third round on Sunday, but said his straight-sets win over Victor Hanescu left room for improvement.
The world No. 2 and second seed — a two-time winner in the California desert — saved all five break points he faced on the way to a 7-6 (7/1), 6-2 victory.
“It was one of those days where you get to serve well and everything else is just kind of trying to find the way to play the right shots at the right time,” said Djokovic, who notched his seventh win over the 87th-ranked Romanian in as many career meetings. “I didn’t make any returns in the first set. [In the] second set I also struggled with the return, which is one of my better sides in the game, generally speaking.”
Djokovic, who won at Indian Wells in 2008 and 2011, has played sparingly this season, falling in the quarter-finals of the Australian Open to eventual champion Stanislas Wawrinka of Switzerland and losing in the semi-finals at Dubai to another Swiss, Roger Federer.
