West Indies 15 June fell well short of chasing down South Africa’s total of 343 in an eventual 139 loss to the Proteas in the Tri-Nations Series.
South Africa bowler Imran Tahir limited the Windies to 204, taking seven wickets for 45 runs in the process.
Johnson Charles led the West Indies with 49 runs while Hashim Amla smashed 110 to become the fastest to 23 ODI tons.
“It’s obviously disappointing,” West Indies Captain Jason Holder said. “Obviously we weren’t good enough today. We were totally outplayed by South Africa. I didn’t think we bowled well, especially in the first 10 overs. We were just lackadaisical. Just leaked too much runs in the first 10 overs.”
South Africa now leads the points table with 10, one clear of Australia. The Caribbean side sits in third place with eight points.
The tournament now moves to Barbados, where the Aussies face the Proteas on Sunday 19 June.
