Bulawayo:The West Indies made Zimbabwe pay for letting a good start slip on Friday to win the fourth one-day international by five wickets and take an insurmountable 3-1 series lead.
Zimbabwe openers Vusi Sibanda (96) and Hamilton Masakadza (80) put on 167 for the first wicket before Masakadza was stumped for 80 off the bowling of Rawl Lewis in the 37th over.
Zimbabwe then lost eight wickets for just 65 run in 13.1 overs at Queens Sports Club to total 232-9.
Runako Morton hit 79 off 109 balls, Marlon Samuels 62 off 71 and Bravo 41 off 41 as the West Indies reached 234-5 with three overs to spare and clinch the series ahead of Sunday's final game in Bulawayo.
West Indies captain Dwayne Bravo won the toss and put Zimbabwe in to bat.
Sibanda was run out for 96 in the 39th over, and Zimbabwe's innings lost momentum completely.
Much of that had to do with the good bowling of Jerome Taylor, who ripped through a Zimbabwean middle order intent on playing attacking strokes rather than consolidating the team's impressive start.
Taylor finished with career-best figures of 5-48 off his 10 overs.
The West Indies lost opening batsman Dwayne Smith off the first ball of the team's reply. But only Zimbabwe captain and offspinner Prosper Utseya troubled the batsmen thereafter. He took 3-40.
