Stokes has yet to return to his best after his latest injury setbacks and was subdued for much of the one-day series against India but Root insists he is not distracted by the prospect of his day in court. England bowlers Adil Rashid and David Willey grabbed three wickets each and India captain Virat Kohli made 71 for the touring side.
The three-match series is level at 1-1 after India won the first ODI at Trent Bridge by eight wickets and England triumphed by 86 runs at Lord´s on Saturday.
Having whitewashed a weakened Australia 5-0 last month, the manner of victory in Tuesday's winner-takes-all clash would have further encouraged England, who will look to win the World Cup for the first time next year as hosts. Kuldeep's statemate and a wrist spinner himself, Piyush Chawla, feels Root got the confidence to go on the backfoot because the pitches were a little slower.
With the eight-wicket defeat on Tuesday, Virat Kohli's unbeaten streak as captain in bilateral ODI series came to an end as well.
"It was something that I immediately regretted", Root said.
He said: "You'd think if you were going to do a celebration like that you'd have smacked it 30 yards out of the ground but it didn't really get there did it? I'm surprised that his turn has reduced over the years, but this one was an unbelievable ball", said Kohli who is now looking forward to the five-Test series. "Everyone in the England team will hold their hands up and say in the first game we were absolutely drilled, we were beaten into the dirt". According to him, MS Dhoni wanted to show the ball to bowling coach Bharat Arun to have a general idea of the nature of the wicket and the field.
'You can see when he's on the cricket field he's fully engaged with what's going on.
Root (100 not out) and Morgan (88 not out) shared an unbroken third-wicket stand of 186 as England won with 33 balls to spare.
