A precise jump smash evened things before Prannoy went into a lead with Axelsen going wide. Axelsen restored parity at 7-7 with Prannoy's wristy net shot going wide. A couple of sloppy returns from Axelsen gave Prannoy two point lead at the break.
A slew of attacking returns gave Prannoy another point. The Indian produced another precise on-the-line smash followed by another down the line return to take the lead to 15-10. Axelsen went out and soon it was 17-10.
The Indian was 18-11 up next with Axelsen going long. He sprayed twice to net as Axelsen send down a whipping straight smash. Prannoy won a 47-shot rally next after Axelsen sprayed into net.
The Indian grabbed six game points and converted in the second attempt after Axelsen went wide.
In the decider, the two played some excruciating rallies to move neck and neck from the start. The Indian played some accurate returns and moved to 7-5.
A straight down the line smash from Prannoy coupled with weak returns from the Axelsen saw the Indian gain a 11-6 lead at the interval.
On resumption, Axelsen tried to play the angled returns but Prannoy managed to stay ahead at 14-9 after winning a video referral.
A cross court smash and a steep straight return helped Axelsen make it 11-14. Prannoy showed good control, producing yet another precise smash on the lines before unleashing a whipping backhand to move to 16-11.
Axelsen sent another wide as Prannoy led 18-14. An error on the net from Axselsen gave Prannoy five natch points. He squandered one before converting the next as Axelsen sent wide again.
Talking about his new shots, Prannoy said: "Before coming for Worlds, we had a week's time, all we do was practice some few shots, learn something new, so there was this shot at 19-19 yesterday, that didnt work but the guts to try something new is a never ending process.
"We are trying to find new shots because we are playing against top 10, top 20 every week. I might come out with a new shot next week."
