Asian Games bronze-medallist Sanathoi defeated South Korea's Hyebin Kim in straight rounds in below 52 kg semifinals, Pooja beat Sherouk Mansour of Egypt in straight rounds in 75 kg weight category. The two Indians face Chinese opponents in the finals tomorrow. Sanathoi will take on world champion Lunn Zhang and Pooja will fight against Yuan Li.

Besides Sanathoi and Pooja, two others — Surya Bhanu Pratap Singh and Uchit Sharma — will feature in semifinals.
