Mirjana Lucic-Baroni continued her fairytale run at the Australian Open by advancing to her first Melbourne Park semi-final with a 6-4 3-6 6-4 victory over fifth seed Karolina Pliskova on Wednesday.
The 34-year-old Croatian, whose only other grand slam semi-final was against Steffi Graf at Wimbledon in 1999, will face second seed Serena Williams, for a spot in the final.
Serena beat British star, Johanna Konta in two straight sets, 6-2 6-3 in the second quarter final match at Rod Laver Arena.
Luci-Baroni’s match saw several swings of momentum with neither player really able to seize control, while Lucic-Baroni had trouble holding her serve when playing into the sun.
The Croat took a medical time out in the third set while trailing 4-3 but returned to win the next three games with ease to make the last four.
