 "WI vs ENG: Salt's second T20 hundred levels series for England in Caribbean")
World champion England set up a Twenty20 series-deciding match with the West Indies after crushing the fourth game by 75 runs.
A second consecutive century by opener Phil Salt from a flying start with captain Jos Buttler set up England's highest T20 score of 267-3 on Tuesday.
The West Indies stayed with the run rate required but couldn't stop leaking wickets and was all out for 192 in the 16th over.
"A fantastic win," Buttler said.
"You don't play in too many of those games. It was like being at the Hong Kong Sixes. Great to be going into the last game of the tour at 2-2."
The fifth and final match is on Thursday at the same Brian Lara Stadium.
Salt and Buttler racked up 117 runs in 9.5 overs. Buttler was caught on the boundary for a 29-ball 55.
