At lunch, McCullum was batting on 202 with the help of 28 boundaries and three sixes off 280 balls. Ish Sodhi was giving him company on 18 as Ishant Sharma was the most successful Indian bowler picking up four for 122 in 30 overs.
This is McCullum's second double century in Tests and also became the fourth Black Caps player to achieve the feat of scoring two or more double hundred in Tests.
Starting from the overnight score of 329/4, it didn't take much time for McCullum and Corey Anderson (77) to get going as their fifth wicket stand yielded 133 runs.
Despite overcast conditions again, they were on top of the Indian bowling from the very outset, looking to score as many runs as possible. In the third over of the day, the skipper brought up his 150-run mark, while in the next one, Anderson reached his half-century, off 88 balls, with seven fours and one six.
Perhaps that led to the next bit of action as Ishant changed his line in the 100th over, coming around the wicket, and was able to get a leg before decision in his favour.
