World Juniors Finalist Sum Yiu Li Commits To Cal For 2027 (25.03 50 FR/54.87 100 FR LCM)

Fitter and Faster Swim Camps is the proud sponsor of SwimSwam’s College Recruiting Channel and all commitment news. For many, swimming in college is a lifelong dream that is pursued with dedication and determination. Fitter and Faster is proud to honor these athletes and those who supported them on their journey.

Sum Yiu Li of Hong Kong has announced her commitment to continue her academic and athletic careers at Cal in fall 2027.

Li represented Hong Kong at the 2025 World Junior Championships and finished 7th in the 50 free with a 25.34. She also was 9th in the 100 free with a 55.05. She also swam at the 2025 World Championships, finishing 30th in the 50 free (25.54) and 31st in the 100 free (55.58) while also swimming on two relays.

Her best time in the 50 free of a 25.03 comes from July 2024 when she most notably broke Siobhan Haughey‘s old junior city record at the Hong Kong Open Swimming Championships. Li holds the Hong Kong junior record in the 50 free.

Li’s Best LCM Times (With SCY Conversions):

  • 50 free: 25.03 (21.82)
  • 100 free: 54.87 (47.99)

The Cal women are coming off of a successful 2026 NCAA Championships that included a 4th place finish, the team’s highest since 2021. Freshman Claire Weinstein led the way and was highlighted by an NCAA title in the 500 free.

Based on her best converted times, Li is a huge addition to the team’s sprint group as her 50 free time would have been 2nd on the roster and her 100 free would have been 4th. Their 200 free relay was 5th at 2026 NCAAs.

Li will arrive in fall 2027 and join the class of 2031 that includes Mia Su (breaststroke) and Alba Arnall (fly/back). The class of 2031 will follow a strong class of 2030 that includes #5 ranked Kelsey Zhang and #9 ranked Ava De Anda. Also in the class of 2030 will be Rylee Erisman, the #2 ranked recruit for 2027 but has reclassified to join the class of 2026 (Cal graduating class of 2030). Erisman and Li were both in the 50 free final at 2025 World Juniors.

I can definitely see her committing to Cal. She would be somewhat close to home, and they have a good sprint group that’s just getting better
