Among other Indians in the fray, B Dhiraj lost to Spaniard Daniel Castro while Mexican Angel Alvarado beat Tarundeep Rai.
“I’ve been working for so many years, and I’m finally showing some progression,” Atanu told World Archery after his quarterfinal. “It would be great to win and to see Deepika do the same. It is a good start. I’m working on myself, on my mental side and I think this is helping me a lot to perform well.”
