BERLIN (AP) — Americans Jessica Pegula and Madison Keys lost to Victoria Azarenka and Liudmila Samsonova in the quarterfinals of the German Open on Friday.
Pegula, who beat the fourth-seeded Karolína Plíšková for the fourth time this year on Thursday, was unable to follow up against the seventh-seeded Azarenka, losing 6-2, 5-7, 6-4. The Belarusian was playing her first grass-court quarterfinal since Wimbledon in 2015.
The 106th-ranked Samsonova needed almost 2 1/2 hours to shock Keys 7-6 (4), 2-6, 7-6 (0).
Samsonova plays Azarenka in her second career semifinal on Saturday.
