A series of injuries affected his career but the 21-year-old from Madhya Pradesh is happy with his performance after regaining his full fitness.
"In 2012, I got injured too many times. I had a back injury, I started playing and again I hurt my back in 2013. I worked on my strength and was fit again. But I had an Appendicitis in 2014," Sameer told PTI.
"I have been playing injury free since October, 2014 and I am happy with my game. I won at Tata open last year. I won at Bahrain. I reached the prequarterfinals at All England. I beat World no. 11 and now I became the national champion. So, such performances really have boosted my confidence.
Sameer, who reached the finals of 2015 Senior National Championship, notched up some good victories in the last year, defeating the likes of Vietnam's Tien Minh Nguyen, China's Wang Zhengming, Japan's Sho Sasaki and Hong Kong's Hu Yun. He also achieved a world ranking of 35 after being 262nd spot at the start of 2015.
