Angelique Kerber believes that a more aggressive approach was crucial in her straight sets victory over Victoria Azarenka in the quarter-finals of the Australian Open.
The German had not beaten Azarenka in six meetings prior to Wednesday's clash at Melbourne Park, but at last got one over the Belarusian with a 6-3, 7-5 win on Rod Laver Arena.
Kerber fired 31 winners, 19 of which came courtesy of a brutal forehand, as she out-hit the heavily favoured Azarenka.
Speaking after the match, the seventh seed credited her heavily offensive mindset for the result.
"Before I went on court yesterday I was practicing to be more aggressive," she explained.
"I played very well. I was playing my game from the first point. When I was down 2-5, I was actually playing more aggressive. I think that was the key.
"I served very well and I was moving good. I think the key from this match was that I was playing and I won the match. She doesn't lose it; I actually won it."
Thursday's semi-final will be the third time that Kerber has made it to the last four of a grand slam. At the 2011 US Open, Kerber was downed by eventually winner Samantha Stosur while at Wimbledon a year later she fell foul of third seed Agnieszka Radwanska. Standing in her way now is the unseeded Johanna Konta, but Kerber has insisted that playing a lower ranked player this time around if of no consequence.
"It doesn't matter who I'm playing in the semis," she asserted. "Whoever is in the semis played four very good matches actually, or five matches.
"I will just try to focus on my game. I will try to not think who I'm playing against. I will just try to focus like today, to be aggressive, and then let's see how far I can get here."
