In Ranji Trophy, defending champions Karnataka are looking to post an outright win over Tamil Nadu after reducing them to 113 for three in their second innings on day four of the final in Mumbai today. Karnataka had posted a massive total of 762 in their first innings, after bundling out Tamil Nadu for a paltry 134. At stumps on the penultimate day, Tamil Nadu were struggling in their second innings, still trailing the title holders by a huge 515 runs with seven wickets remaining. Prolific Karnataka batsman Karun Nair scripted history by becoming the first batsman in independent India to score a triple ton in any Ranji Trophy final . Nair, who hit a mammoth 328 against Tamil Nadu, eclipsed the previous best score of 319 by Gul Mohammad for Baroda against Holkar in 1946-47. The 23-year-old also surpassed legendary batsman Gundappa Vishwanath's 247 against Uttar Pradesh in 1977-78, for the highest runs scored by a Karnataka batsman in a Ranji final.
