Srikanth defeated World No. 1 San Wan Ho of Korea 21-15 14-21 24-22 to set up a clash with Kazumasa Sakai of Japan, who defeated another Indian shuttler HS Prannoy.
"Coming into the tournament, I never thought really that I will reach the finals again. I am shocked to be playing back to back finals. It will take a while to digest it and then prepare for tomorrow," Srikanth told PTI.
"I won a lot of points and also lost points when my smashes went out but that's the way I play, it is my main scoring option. It was very close match. I was lucky there in the last point. It was a nice game. I am proud.
"I was in comfortable position in the second game also but conditions changed and I lost track. I made simple mistakes and it changed the complexion of the second game but I am very happy to make a comeback in the third game," he explained.

"I think I really had a bad injury after the Olympics. I pushed really hard when I came back and I shouldn't have done that. It was tough. Losing at India Open was a big thing, I pulled out of Malaysia and that one week training helped me to play well at Singapore.
Prannoy, who stunned three-time Olympic silver-medallist Lee Chong Wei and Rio Games gold medallist Chen Long in the last two days, suffered a heart-breaking 21-17 26-28 18-21 loss to Sakai today.
"I am very disappointed with the result but that's how the sport goes and can't really complain. I probably could have taken the second game. I had 4-5 match points. I think probably I could have taken more chances in second.
"Overall, I didn't play badly. Probably, I didn't adjust to the conditions today. It was going out a lot from the other side. I wasn't good in the second half," he said.
"He was really fast and I wasn't moving quickly. Towards the end I was getting the feel of the shuttle better but I was really late in coming back at 17-12 and fight it out.
"He is a tricky player. All Japanese player are quick, he was little better in the net today and his net dribble was coming through well for him and all the credit to him, he deserves to be in the finals.
"I am happy with the way tournament went, lot of positives, lot to learn and I can go back and work on couple of aspects," said Prannoy.
