Moeen Ali played down his record-breaking 53-ball hundred as a "bit of a slog", but said that the confidence he has gleaned in the course of a phenomenal summer in global cricket allowed him to trust his instincts and put West Indies' bowlers to the sword in a run-laden third ODI at Bristol.
The biggest concern for West Indies ahead the 3rd ODI was the injury scare for their swashbuckling opener Chris Gayle.
Man-of-the-Match Ali's hundred was also the second quickest by an England batsman at this level after Jos Buttler's 46-ball ODI century against Pakistan in Dubai in 2015. The previously in-form Jonny Bairstow mistimed an easy return catch back to Holder, but Root was soon under way with three consecutive leg-side boundaries off Jerome Taylor as he and Alex Hales transformed the early scoring rate.
He eventually holed out off spinner Ashley Nurse and received a standing ovation from a near-capacity crowd.
"I enjoyed myself", Ali told Sky Sports.
"They bat deep. [Moeen] has played a special innings today". However, the captain Jason Holder has confirmed the fitness of Gayle and said that he is ready and raring to go. "The players need to take the ownership on themselves".
West Indies reached the first three World Cup finals, all staged in England, winning the inaugural edition in 1975 and repeating that achievement in 1979 before suffering a shock defeat by India at Lord's in the climax of the 1983 edition.
Plunkett then had both Shai Hope (20) and Marlon Samuels (11) caught behind, the latter on a tight review.
Earlier, all-rounder Ali sprinted to his hundred with almost half of his runs coming via eight sixes, before he fell for 102.
The tourists were in no mood to go too quietly, despite Liam Plunkett's maiden five-wicket haul, and took the match maximum count to 28 - Chris Gayle (94) with six, including three in succession off Moeen - in their 245 all out.
