WATCH: Best yorker of 2019 World Cup

New Zealand pacer Lockie Ferguson bowled a searing yorker to dismiss South Africa captain Faf du Plessis, during the 2019 International Cricket Council (ICC) World Cup match at Edgbaston on Wednesday.

South Africa found runs hard to come by against disciplined New Zealand bowling as they desperately sought a victory to keep their World Cup hopes alive.

After a soggy outfield delayed the start at Edgbaston and reduced the match to 49 overs per side, Black Caps captain Kane Williamson won the toss and chose to field, hoping to take advantage of bowler-friendly conditions.

He was rewarded in just the second over when Trent Boult demolished Quinton de Kock's stumps, sending him back for just five.

Hashim Amla and skipper Faf du Plessis played some fluent shots as the Proteas recovered to reach 59-1 in the 14th over.

But Lockie Ferguson then produced a yorker to bowl Du Plessis for 23 immediately after a testing bouncer.

Williamson anchored New Zealand to a tense four-wicket victory after an astonishing stroke of luck when South Africa failed to review an edge from the Kiwi captain.

That decision could prove fatal to their tournament hopes, with the Proteas now needing a miracle to progress to the semi-finals after just one win from six matches, while New Zealand now top the 10-team table.
