Joe Root became the first player to mark a 100th Test cap with a double century as England made India toil again on day two of the series in Chennai. Day 2 Blog | Scorecard | News
Root resumed on 128 at M. A. Chidambaram Stadium on Saturday and the captain went on to make a magnificent 218, putting on 124 for the fourth wicket with the brilliant Ben Stokes (82).
The tourists were in a commanding position on 555-8 at stumps on a day which saw the imperious Root take centre stage once again.
Yorkshireman Root moved above Alec Stewart to go third on the list of England's leading Test run-scorers with another masterclass, taking his staggering tally of runs to 644 in his last three Tests.
Having made 228 in the first innings of the first Test against Sri Lanka and a century in the second match in Galle, where England sealed a 2-0 whitewash, Root registered his fifth double century in the longest format as India bowlers were made to suffer in the heat.
Jasprit Bumrah removed Dom Sibley for 87 in the final over on day one, but Virat Kohli's side failed to make a breakthrough in the morning session on the second day.
Root was 156 not out at lunch and Stokes on 63 with England in command at 355-3 and Stokes was the only man to fall before tea, caught by a juggling Cheteshwar Pujara off Shahbaz Nadeem in the deep.
Ollie Pope made 34 on his return from a shoulder injury before he fell to Ravichandran Ashwin and Root's marathon knock was finally ended when he was trapped leg before by Nadeem, with England 477-6.
Ishant Sharma bowled Jos Buttler (30) and Jofra Archer first ball, but Dom Bess and Jack Leach were still there at the close. Rohit Sharma inexplicably dropped Bess at midwicket on 18, which just about summed up India's day.
Relentless Root leaves India in double trouble
After becoming the ninth player to make a hundred in his 100th Test on day one of the series, Root went on to etch his name in the record books.
The 30-year-old put on another exhibition of how to bat against spin, using his feet superbly, sweeping impeccably and showing incredible powers of concentration.
Root spent almost nine hours at the crease before he was trapped in front by Ashwin, hitting two sixes and 19 boundaries. Kohli offered a handshake as he made his way back to the pavilion after one of the great Test knocks.
Stokes hits the ground running, Ishant on the brink of landmark
Stokes missed the 2-0 whitewash of Sri Lanka last month, as he was given a hard-earned rest.
There was no rest for India in the field as the all-rounder hit the ground running in his first match of the year, clearing the rope three times and hitting 10 fours.
Paceman Ishant was impressively economical on a flat track. He was on a hat-trick after cleaning up Buttler and Jofra Archer, but Jack Leach denied him that feat.
