Submitted by Kumuda on Mon, 2016-12-19 17:17 Chennai: Promising Karnataka batsman Karun Nair on Monday became only the second Indian – after Virendra Sehwag – to slam a triple hundred in Test cricket as he remained unbeaten on 303 against England in the fifth and final Test here. Riding on Karun Nair's breath-taking unbeaten triple ton, India declared their first innings at a mammoth 759/7 and took a 282-run lead against England in their fifth and final cricket Test here on Monday. This is India's highest score against any opponent surpassing the previous best of 726/9 declared against Sri Lanka in 2009. Playing only his third Test, the 25-year-old Nair forged two major partnerships -- 181 for the sixth wicket with Ravichandran Ashwin (67) and then 138 for the seventh wicket with Ravindra Jadeja (51) -- to take India to the record total at the M.A. Chidambaram Stadium here.
