- Caroline Wozniacki racing the clock with leg injury: Top seed Caroline Wozniacki lost, 6-4, 6-2, to Varvara Lepchenko in the second round of the Bank of the West Classic on Thursday night. Wozniacki played the match with heavy tape on her lower left leg. "Physically I wasn't 100% but I still thought with the adrenaline and everything I thought I could warm it up and play and still win. Especially it was the first match back after a long break and the court was fast so it didn't give me a chance to get into rhythm. It wasn't pretty out there, that's for sure." Wozniacki told reporters the leg is getting better every day.

- Agnieszka Radwanska stays mum on injury concerns: The No.2 seed in Stanford was able to rebound from losing the first set to reel off 12 straight games and beat Misaki Doi, 1-6, 6-2, 6-0, in the second round on Thursday afternoon. Afterwards she told reporters she was fully fit when she arrived in Stanford but picked up an unspecified injury on her first day at the tournament and did not practice during the week. She declined to give any further details.

- Report: Eugenie Bouchard has ended her coaching relationship with Sam Sumyk. She will work with Marko Dragic at the Rogers Cup in Toronto. Bouchard and Sumyk began working together after the Australian Open.

- Stanford quarterfinals: Karolina Pliskova vs. Ajla Tomljanovic, Elina Svitolina vs. Alison Riske, Varvara Lepchenko vs. Mona Barthel, and in the blockbuster of the day, Agnieszka Radwanska vs. Angelique Kerber. Play begins at 11am PT.

- Washington DC quarterfinals: Monica Niculescu vs. Sam Stosur, Louisa Chirico vs. Sloane Stephens, Ekaterina Makarova vs. Irina Camelia Begu, and Anastasia Pavlyuchenkova vs. Christina McHale. Play begins at 1pm ET.

- Lepchenko's fitness back on track: Reflecting on her season, Lepchenko told reporters that an illness in February completely disrupted her year. She struggled to get her fitness and confidence back and came into Stanford on a six-match losing streak dating back to the clay. Instead of taking a break after her first round exit at Wimbledon she opted for a heavy training block in the gym and it's already paid off.

"The very first day after Wimbledon I started with my physical conditioning. I worked really hard to get to this point. I think I'm in better condition now than I was at the beginning of the season."

- Nice report from The Tennis Island on Christina McHale's run to the Citi Open quarterfinals. McHale booked her spot with a comeback win over Yulia Putintseva, rallying from two breaks down in the final set to win, 6-2, 1-6, 7-5.
