If he had won this match, Srikanth would have faced compatriot HS Prannoy in the next round.
Sindhu, after the match, was simply happy to have won it.
Just like their World Badminton Championships final past year (where Okuhara won), the match was full of long and tremendous rallies.
How have their past meetings panned out? .
Coming to today's game, Sindhu lost the first set to the Japanese player by 20-22. It's been like 10 times we have played and we've won five times each. Okuhara then sent one over the back line to hand over a game point to Sindhu, whose return got buried at the net after breaking the strings of her racquet as it was 20-20.More news: US, France, Germany blame Russian Federation for United Kingdom nerve agent attack

On Friday, Sindhu and Okuhara added yet another added chapter to their every-growing rivalry. Looks like they don't really care about our years of struggle and hard work to achieve our goals. But the second and third game saw Sindhu make comebacks to win her the match and advance.
Tournament favourites Marcus Fernaldi Gideon / Kevin Sanjaya Sukamuljo (pictured) are on track to defend their title in Birmingham after beating Chen Hung Ling / Wang Chi-Lin in straight games, 21-15, 21-13.
"It was a tough match and I think both of them are used to playing long matches, and it is good that she ended on the right side this time but Okuhara has been a fantastic fighter and it is great entertainment for the spectators", he said.
She will face the victor of 2016 Olympics Gold Medalist Carolina Marin and second-seeded Japanese Akane Yamaguchi on Saturday for a place in the final. Yamaguchi lost a game against countrywoman Sayaka Sato in the second round, in what was a highly entertaining and fast-paced encounter. However, it was Sindhu's day as she managed to outclass her opponent by a score of 21-18. However, Yamaguchi was a lot more forthcoming.
Sindhu showed the vast grit and fighting spirit that she is known for and even though there were some errors from her side that pegged her back, she did not let that bother her and came out triumphant.
"We played with them many times, and we always win so we know how they play and we have already learned about them". Yesterday I didn't get even one, today it was totally changed. At last year's World Championships final against Okuhara, she was warned for the same reason. She is also on an eight-match winning streak and has spent one hour and eight minutes less than Sindhu on court in this tournament. While the No 4 seed had virtually sleepwalked through her jousts with the Thai twosome of Pornpawee Chochuwong and Nitchaon Jindapol in her earlier rounds, she was sharp and focused against the seventh-seeded Okuhara, realising that the slightest slip in concentration against the pint-sized Japanese dynamo would be fatal. A flat return on the forecourt and then a return at the back from close to the net gave Sindhu a 11-9 lead at the breather.
