JOE ROOT defied an unpredictable pitch to make a timely return to form as a risk-free unbeaten century stabilised England on a seesaw opening day of the fourth Test against India in Ranchi.

On a cracked surface offering significant early assistance for India’s bowlers, Ben Stokes’s dismissal to a Ravindra Jadeja grubber left England on 112 for five at lunch after debutant Akash Deep’s three-wicket haul.

But Root, averaging 12.83 after the first three matches, ended his lean patch with a battling 106 not out, which included a 113-run stand with Ben Foakes, as England went to stumps on 302 for seven.
