Sixteen-year-old Lakshya, who clinched the Bulgarian Open this year, showed great athleticsm but lacked control and anticipation. He did surprise his senior pro with some of his strokes but it was not enough to dethrone Srikanth.
After the interval, Srikanth, managed to keep his younger opponent at bay as he slowly extended the lead and sealed it comfortably in the end.
In the second game, Srikanth seemed in control initially as he led 11-7 at the break. But Lakshya produced an entertaining run of play, reeling off seven points on the trot to move into a two-point lead from 7-12 to 14-12.
However, despite his best efforts, it was Srikanth who had the last laugh as he moved ahead to a 18-15 lead with a smash and closed the issue when Lakshya found the net.
It will be another pulsating battle between Srikanth and Prannoy, who have played four times in their international career but it was the former who had the last laugh on last three occasions. The only time Prannoy had beaten Srikanth was way back in 2011 at Tata Open.
Prannoy too have been in fine form as he reached the semifinals at Indonesia Super Series Premier and French Open Super Series to achieve his career-high ranking of World No 11. He had outwitted Chong Wei twice and defeated Chen once during the season.
