In just under an hour and a quarter and with the set numbers 6-1, 6-0, Azarenka advanced to the semifinals where Serena Williams is waiting.

- I felt that I stuck to my plan, says the two-time grand slam winner Azarenka.

Williams defeated Azarenka in the US Open finals in 2012 and 2013, the same two years Azarenka took home the Australian Open.
