Umesha Thimeshani made her name in Sri Lankan domestic cricket when she represented Kandy in the Super Provincial Women's T20 tournament. She made her T20I debut against South Africa in February 2019. Her ODI debut was in the same series too.
The allrounder was impressive during the South Asian Games in late 2019, posting 56 against Bangladesh as well as returning figures of 4-8 against the same nation in the final.
Thimeshani was included in Sri Lanka's squad for the ICC Women's T20 World Cup 2020.
