Only one player has hit more sixes in a first-class match - 23 by Colin Munro in the Plunket Shield in 2014-15; he hit all those in a single innings. The previous record by an Indian player was 15 sixes by Yusuf Pathan in the Duleep Trophy final in 2009-10. Pant has hit 44 sixes this season, the most by a distance.
113.01 Pant's strike rate this season, the best among batsmen who have faced 100 or more balls. He had a strike rate of over 100 in six out of seven innings this season, and the only innings in which he did not do so was his triple-century - 308 off 326 balls.

His bowling average is the best among all bowlers to take more than 15 wickets in this season.
