Jonny Bairstow plays a shot en route his match-winning knock

A century from Jonny Bairstow and a 96 from Jason Roy helped England to a convincing nine-wicket win in the fifth and final One-Day International in Southampton on Friday. In the process, England finished the series 4-0, with the second match ruined by rain.

Bairstow, who had started the series with a century, ended on 141 not out while Joe Root scored 46 not out as England completed the chase in 38 overs, finishing on 294 for 1. Windies had earlier posted 288 for 6 from its 50 overs after being asked to bat first.

Chasing 289, England got off to a terrific start with Bairstow and Roy adding 156 for the opening wicket off just 21.2 overs.

The tone was set early by the duo when they took the attack to Alzarri Joseph, the Windies pacer who had impressed with a five-wicket haul in the previous match. Roy and Bairstow took 21 off his first two overs and did the same to Miguel Cummins as England plundered 71 runs in the first ten.

The only time Windies managed to trouble England was when Cummins thought he had Roy leg-before in the eighth over, but it ended with a wasted review as the replays showed the ball missing leg stump. Roy went on to reach his half-century off 43 balls while Bairstow got his later, off 48 balls.

The dual assault made Windies try Marlon Samuels with the ball for the first time in the format since November 2015, but Roy smashed the offspinner for a big six in a three-over spell that cost 28.

Against the run of play, Roy was trapped in front by Cummins four short of a century, but Bairstow was not missing out on his. In the steady company of Root, the opener got to his second ODI ton off his 90th ball while Root soon finished the series in style with a six.

Earlier, Chris Gayle's cameo (40 off 29 balls) and Shai Hope's patient 95-ball 72 helped Windies go past 250.

Windies managed just nine runs in the first four overs before Gayle cut loose, hitting 34 runs off just six balls, all delivered by Jake Ball. It included four successive sixes, but Tom Curran, the debutant, induced a mis-hit from Gayle with a slower ball, with Liam Plunkett taking a fine diving catch running backwards from mid-off.

England re-established control as Shai joined his brother Kyle at the crease, with both batsman resorting to more orthodox methods. Plunkett himself forced the next breakthrough, taking a fine catch off his own bowling to dismiss Kyle for 33.

Adil Rashid and Moeen Ali, the spinners, kept things tidy and Samuels struggled to get any sort of rhythm. Incredibly, Windies did not score a boundary between the ninth and 31st overs.

Samuels eventually broke the deadlock with a four off Plunkett but was dismissed in the next over for an agonising 32 off 60 balls, stumped by Jos Buttler off Moeen.

Shai brought up his 50 with three fours off Curran but Windies could not post a mammoth total, despite late cameos from Sunil Ambris (38 off 27 balls) and Ashley Nurse (31 off 12).
