Kerber in Pan Pacific Open semifinal

Tokyo - Persistent rain washed out the rest of the quarterfinal matches

Fourth seed Angelique Kerber reached the Pan Pacific Open semifinals in Japan on Friday after American Madison Keys retired due to injury early in the deciding set.
With the match clock at just over two hours, Kerber grabbed an early break to lead in the final set at 6-4 4-6 2-1, before Keys pulled out of the contest.
"It was a really good match in the first two sets, and this is never the way that you want to win the match," three-time Grand Slam winner Kerber said. "I hope Madison will recover really soon so she is ready for the next tournaments."  
Persistent rain washed out the rest of the quarterfinal matches, with home favourite Naomi Osaka's meeting with unseeded Yulia Putintseva moved to Saturday in the revised schedule.
The semifinal matches have been scheduled for the evening session, the organisers confirmed.
