Angelique Kerber was bundled out of the Hong Kong Open following her straight set loss to Daria Gavrilova in the quarter-finals on Friday.
The world number one would go down 6-3, 6-1 to the fiery Australian for her 16th loss of the season.
Kerber struggled with her serve in the opening set, holding serve just once as Gavrilova broke her no less than four times on her way to taking the set.
In the second set, a double fault would hand Gavrilova a 3-1 lead and hope dwindled for the two-time Grand Slam winner, even squandering two break points in the following game.
An unforced error into the net from Kerber would eventually had Gavrilova the match.

“It’s a long season and we’ve been playing for ten months,” quipped a tired Kerber after the match.
“I’ve been playing a lot of matches this year, and I think I need a few days off to get ready for Singapore because I am tired and I need a lot of treatment to get ready for the next one. I was not serving at my best, I made a lot of double faults which is not normal for my game.”
Gavrilova faces Kristina Mladenovic in the semi-finals, who edged Bethanie Mattek-Sands 3-6, 6-3, 7-6(3) in a thrilling match.
