Jang Su-jeong

Jang had a good career as a singles junior player, reaching her highest ranking in that category as world No. 68. Her best junior Grand Slam tournament was at the 2011 US Open, where she reached the third round. Her lone junior singles title was at the Yangdu International Junior Championships (Gangwon, 2008).

She won her first ITF Circuit title in Bundaberg, Australia on 30 March 2013, winning the doubles tournament alongside Lee So-ra. The pair defeated Miki Miyamura and Varatchaya Wongteanchai in the final in a close three-setter.

Her most successful performance to date came at the 2013 Korea Open, where she reached the quarterfinals with a three-set win over Ons Jabeur.

She qualified into the singles main draw of the 2022 Australian Open for her major debut. She became the eighth South Korean woman to contest a Grand Slam main draw in the Open Era, and fourth this century following Cho Yoon-jeong, Jeon Mi-ra and Han Na-lae.^[1]

She won her first WTA Challenger title at the 2022 Swedish Open where she defeated Rebeka Masarova in the final.^[2]

At the 2023 Korea Open, she upset fifth seed Sofia Kenin.^[3]
