The skipper praised Bairstow, Roy, and Root who helped them to cross the line.
"I'm pretty pleased," Bairstow said talking about his own form.
Since Root's debut in 2013, only Virat Kohli and AB de Villiers have scored over 4000 runs in this format.
Here we look at all the stats and records created during the game.
Joe Root finished things in style with a six as England went on to win the game by 9 wickets.
Jonny Bairstow collected the player of the match award for his 141 off 117 balls and frankly, this was the best English summer in their cricket history.
He scored 72 in the game which is his 4th ODI fifty.
West Indies will be without their skipper Jason Holder and explosive opener Evin Lewis.
Jason Mohammed will be leading the West Indies side playing in his 21st ODI.
Some swashbuckling innings by batsmen from both the teams set the tone for the day.
