I see great improvement in Lakshya's tactical acumen: Vimal Kumar

The dream run of Lakshya Sen surprised many but not his mentor and coach Vimal Kumar. Lakshya got a walkover in the quarterfinal of the All England Championship on Friday and will play the semifinal against Malaysia's Lee Zee Jia, who defeated Kento Momota of Japan 21-7, 13-21, 21-11 in another quarterfinal.
