2018: Major debut and junior champion Wang booked her ticket to her
major debut at the
2018 Australian Open on 3 December 2017 in
Zhuhai by winning the
Asia-Pacific Wildcard Playoffs, coming back to edge out the Papua New Guinean No. 1,
Abigail Tere-Apisah, in the final. Tere-Apisah was only two points away from victory when leading 5–3, 30–0 in the second set, looking to become the first player from Papua New Guinea to compete in a major main draw, when momentum shifted and Wang, demonstrating fearlessness for her age, won the next seven points, before going on to level the match. Wang eventually won the match in three sets, seizing the most crucial break with a splendid backhand passing shot in the ninth game, and then closed out the final set after saving four break points. "It's probably the most important day in my life so far," Wang said in the post-match news conference to
CCTV Sports Channel, the official TV broadcaster of the
Australian Open in China. At the 2018 Australian Open, as the second youngest competitor in the main draw (just older than 15-year-old
Marta Kostyuk), Wang lost her debut match at a major to
Alizé Cornet, in straight sets. But going through to the
