BENGALURU: December 19, 2016 will be etched in the annals of Indian cricket as the day a young Karun Nair became the second Indian to score a triple hundred. A lot has happened since then in the Karnataka batsman's career.He's seen the high of IPL captaincy to the low of a lean patch with the bat and being left out of the squad for Sri Lanka. As the 25-year-old looks at rebuilding his career, Karun has to also work on shedding the baggage of his unbeaten 303 which he cracked against England. Almost 10 months after the epic innings, conversations with him continue to revolve around the landmark.Admitting that it has got a little overbearing, Karun said: "Yes, it is getting to a point that I want to tell people to move on because I have bigger and better things to look forward to."While the questions don't bother him on field, it is different off it. "I don't think about it when I'm on the ground because I just shut out everything else and concentrate on my game. But sometimes it does cloud the mind, especially during a lean patch. So, I often tell myself, 'I've worked very hard to get those 303 runs and nobody can take that away from me, so, I have to shut out conversations and concentrate on achieving bigger goals.'Karun moved in this direction earlier this month, with a captain's knock of 90 against South Africa 'A', which helped India 'A' win the second 'Test' and level the two-match series."It was a different challenge because I had to handle 11 different people from various states. It's a little hard because you haven't played along with then and you don't know them I quite enjoyed it because it is a huge learning experience," Karun said about the leadership challenges of India 'A'.The talented batsman also pointed out that he wasn't losing sleep over not being in the Indian team's dressing room and is instead working hard to make the opportunities count."It is difficult when you are out of the squad. I took it in my stride and told myself I have to look keep working hard and make use of all the opportunities. Wherever I'm playing I just have to keep getting runs. If I keep getting runs I know I will get back."
