Mayank Agarwal's maiden triple-century drove Karnataka to 628 for 5 and a first-innings lead of 383 against Maharashtra at the MCA Stadium in Pune. Agarwal, who came into this match on the back of a pair, notched up an unbeaten 304 off 494 balls that included 28 fours and four sixes. Agarwal had put on 259 for the opening wicket with R Samarth (129) on the second day and resumed on 219. He stretched his third-wicket partnership with Karun Nair to 279. Nair, who was not out on 56 overnight, struck a century of his own, finishing with 116. Karnataka declared shortly after the pair was broken up. Thereafter, medium-pacer Abhimanyu Mithun took Karnataka closer to an innings win by dismissing Maharashtra's openers cheaply and leaving them at 49 for 2 at stumps. Maharashtra are behind 334 runs.
