NOTTINGHAM, England (AP) Former Wimbledon finalist Agnieszka Radwanska dropped just four games against Christina McHale on Thursday to advance to the quarterfinals of the grass-court Nottingham Open, where she will meet another American.

The top-seeded Radwanska won 6-3, 6-1 in the second round of the Wimbledon warm-up tournament, and next plays Lauren Davis.

Radwanksa has had a poor 2015, and lost in the first round of the recent French Open, but favors the grass surface and has won two matches this week for the loss of seven games. She lost in the 2012 Wimbledon final to Serena Williams in three sets.

Ana Konjuh of Croatia beat sixth-seeded Casey Dellacqua 6-4, 6-2, while Yanina Wickmayer and Johanna Konta were also second-round winners.
