Lea Nilsson Advances to US Open Junior Semifinals, a Historic First for Sweden

Lea Nilsson reaches the semifinals of the US Open junior tournament, a first for Sweden since 2015.

Key Points

  • • Lea Nilsson is the first Swedish junior in a grand slam semifinal since 2015.
  • • She defeated world number one Julieta Pareja in earlier rounds.
  • • Nilsson won her quarterfinal match in straight sets.
  • • She is set to face Mika Stojsavljevic in the semifinals.

Lea Nilsson, a 17-year-old tennis prodigy from Stockholm, has made history by reaching the semifinals of the 2025 US Open girls' singles junior tournament. This accomplishment marks the first time a Swedish junior has reached this stage in a grand slam event since Mikael Ymer in 2015.

In a remarkable display of skill, Nilsson triumphed over the junior world number one, Julieta Pareja, before continuing her winning streak against eighth-seeded Charo Esquiva Banuls from Spain, whom she defeated in the quarterfinals with a decisive score of 6–4, 6–1. Her success breaks a significant gap, as no Swedish junior player had reached the semifinals in a grand slam since 2019, and the last to win a title was Daniel Berta in 2009.

Nilsson's impressive run in Flushing Meadows has captivated local fans and tennis enthusiasts alike. In the semifinals, she is set to face ninth-seeded Mika Stojsavljevic from the UK, with hopes of advancing to the finals, which would be a historic achievement for Swedish junior tennis.
