H.S. Prannoy

Prannoy came to prominence after winning the silver medal in Boys' singles at the 2010 Summer Youth Olympics. He followed it up with another silver, this time at the Bahrain International Challenge, in 2011. However, as he struggled for form and injuries, Prannoy endured a somewhat barren spell following these achievements.

In 2013, Prannoy managed to reach the final of the Tata Open International Challenge in Mumbai, eventually losing to compatriot Sourabh Verma in the final.

In 2014, Prannoy claimed two All India Senior National Ranking Championships: Manorama Indian Open All India Senior Ranking Badminton Tournament, Kerala and the V. V. Natu Memorial All India Senior Ranking Badminton Tournament, Pune. However, it was his exploits on the international circuit that caught everyone's attention. He was a semi-finalist at the 2014 India Open Grand Prix Gold, Bitburger Open Grand Prix Gold,2014 Macau Open Grand Prix Gold and the Sri Lanka Open International Badminton Challenge in Colombo.

Prannoy surprised one and all by reaching the final of the 2014 Vietnam Open Grand Prix where he lost to top seed and tournament favourite Dionysius Hayom Rumbaka of Indonesia. In the very next tournament, the Indonesia Open Grand Prix Gold, Prannoy went one better, this time beating local favourite Firman Abdul Kholik of Indonesia in straight sets. He managed to end the year as the third-highest ranked Indian at World no. 21.

Prannoy started off the year on a good note reaching the semifinals of the 2015 India Open Grand Prix Gold. He put up a spirited performance in the semifinals before bowing out to compatriot Srikanth Kidambi in 3 sets. His greatest victory came in the pre-quarters of the 2015 India Super Series, when he beat an in-form world number 2 Jan Ø. Jørgensen in 3 sets. He played his heart out in the quarter-finals as well, but ultimately suffered defeat to Denmark's Viktor Axelsen.

Prannoy started 2016 on a good note by beating German ace Marc Zwiebler in the finals of the Swiss Open Grand Prix gold 21–18, 21–15.

Prannoy played for the Mumbai Rockets franchise in the 2017 season of the Premier Badminton League. In the 2017 Indonesia Open, he defeated the reigning Olympic silver medalist Lee Chong Wei and the reigning Olympic champion Chen Long in consecutive matches, but lost to Japanese Kazumasa Sakai in the semi-finals. At the 2017 U.S. Open, he defeated Vietnamese Nguyễn Tiến Minh to reach the finals, where he beat compatriot Parupalli Kashyap to win the title.

Prannoy participated in the 2018 Commonwealth Games, where he finished in fourth place after being beaten by Rajiv Ouseph of England in the bronze medal match. He then won a bronze medal at the 2018 Asian Championships, after beating second seed Son Wan-ho in the quarterfinals. However, he was defeated in the semifinal by third seed Chen Long.

Prannoy had a disastrous start to 2021 after exiting in the early rounds of the 2021 Swiss Open and the 2021 All England Open. However, he came back strongly in the second half of the year, most notably defeating reigning Olympic champion Viktor Axelsen in the 2nd round of the 2021 Indonesia Masters in November. He got further success in the 2021 BWF World Championships, held in December, where he upset World no. 9 Ng Ka Long of Hong Kong in the 1st round and World no. 10 Rasmus Gemke in the pre-quarterfinals. He lost to the eventual world champion Loh Kean Yew of Singapore in the quarterfinals. His consistent performances in the last few months of the year enabled him to rise to World no. 27 at the end of the year.

Prannoy was part of the India squad for the 2022 Thomas Cup. In the quarter-final against Malaysia, he won the decider match against Leong Jun Hao to assure India a semi-final spot and its first-ever medal in the Thomas Cup. He repeated this performance in the semi-final against Denmark, beating Rasmus Gemke in the deciding match to take India to the final, which India eventually won.

Prannoy also had a consistent year on the BWF World Tour, reaching six quarterfinals and two semifinals, as well as the quarterfinal of the 2022 BWF World Championships. This enabled him to re-enter the Top 15 in the BWF World Rankings after 4 years. He also qualified for the BWF World Tour Finals for the first time in his career.
