Seventh seed German Angelique Kerber has reached her first Australian Open semi-final after defeating Victoria Azarenka 6-3 7-5 on Wednesday.
Kerber's quarter-final victory means she has become the first German female to reach this stage of the tournament since Anke Huber in 1998.
Despite being seeded higher than her opponent, Kerber was seen as the underdog having failed to beat Azarenka in six previous attempts.

Kerber didn't let that history bother her though as she raced out to a 4-0 lead in the opening set.
Azarenka roared back to make it 4-3, putting Kerber under the pump for the first time during the match.
However, she held her nerve to stave off four break points and hold serve to make it 5-3.
She then broke her Belarussian opponent once again to close out the set 6-3.
Azarenka, who started the year in superb style by thrashing Kerber to clinch the Brisbane International, had not yet lost a set during 2016.
She responded with vigour, breaking the German in the first game of the second set before blazing her way to a 5-2 lead.
However, she blew five set points to give Kerber hope of clawing her way back into the set.
The 28-year-old chipped away her flustered opponent and eventually overwhelmed her, winning five games in succession to claim the second set and the match.
Kerber faces Konta in semi-final
With the number of upsets on this side of the women's draw, Kerber now has a golden opportunity to go all the way to the final at Rod Laver Arena.
The world number six has been in this position before at the 2011 US Open and Wimbledon in 2012 but failed to take the next step at both times of asking.
The German will now play the 47th ranked Brit Johanna Konta, who beat Shuai Zhang 6-4 6-1 in her quarter-final.
The matchup should be a fascinating contest between two women who have never faced each other before nor reached a Grand Slam final.
