Overview

  • Tjen defeated Veronika Kudermetova 6-4, 4-6, 6-4 in the first round, becoming Indonesia’s first Grand Slam main‑draw match winner since 2003.
  • She reached the main draw by winning three qualifying matches in straight sets, including a victory over third seed Aoi Ito.
  • Tjen is scheduled to face Emma Raducanu on Wednesday, 27 August, with the winner to meet Elena Rybakina or Tereza Valentova in the third round.
  • Her partnership with British coach Chris Bint began about 19 weeks ago and coincides with a ranking climb from around No. 301 in May to approximately No. 149.
  • A third‑round berth would be worth about $237,000 in prize money, a significant figure for a player who has relied on sponsorship to compete from a nation with limited development pathways.
