The scores were level at 3.5 points after the first two segments but the Vietnam player won the first two games of the final phase to secure a spot in the last eight. Vaishali was delighted to put it across Stefanova.

"Yeah, it was great to play a former world champion and defeat her," she told PTI. "I was leading the match after one hour with 5.5-2.5 then in the bullet segment (but) internet got disconnected and I lost on time in an equal position," she said after managing to pip her rival in a close finish.
