The Netherlands have produced a stunning upset to knock South Africa out of the T20 World Cup after a 13-run victory at Adelaide Oval on Sunday.

The Proteas simply needed to beat the associate nation to secure their spot in the semi-finals but allowed the Netherlands to score 158-4, including 45 off the final four overs, before falling apart in the chase, to be 145-8

South Africa's slip-up means the winner of the Pakistan-Bangladesh game at the same venue in fine conditions will finish second in Group 2 and take on Group 1 winners New Zealand in the semis at the SCG on Wednesday. The Proteas' loss also means India go through and top Group 2.

Player of the Match Colin Ackermann was heroic for the Dutch with an unbeaten 41 from 26 balls, helping their late charge, before Brandon Glover (3-9) and Fred Klaassen (2-20) starred with the ball.

South Africa's pursuit never got going after the loss of openers Quinton de Kock (13) and Temba Bavuma (20), but they seemed in a winning position at 90-3 in the 13th over, needing 68 off 46.

Yet it all fell apart for the Proteas with wickets tumbling, as Klaassen had Aiden Markram caught by Stephan Myburgh before Glover grabbed two quick wickets to dismiss potential game-winner David Miller for 17 and Wayne Parnell for a duck. From there, South Africa's tail could not get them near the target.

Van der Merwe delivers the key moment

Roelof van der Merwe's brilliant catch running backwards to dismiss danger man Miller was arguably the moment of the match. South Africa had six wickets left, needing 47 off 29 balls, when Miller mis-timed a hook shot, which was lofted towards fine leg but the 37-year-old never took his eyes off the ball and pulled off a diving effort to re-claim any momentum the Proteas had at that stage.

Another South African World Cup disaster

South Africa's loss and subsequent elimination will be tough to swallow. The Proteas, who have never made a T20 World Cup final and have an inglorious past in the 50-over version, appeared destined for the last four for the first time since 2014. Instead, they suffered their first-ever loss to the Netherlands across any format.
