Ottniel Baartman

David Miller was the Proteas' star with an unbeaten 59, as South Africa recovered from a dismal start in which they had slumped to 12-3.

The Netherlands had started poorly themselves with the bat, though Sybrand Engelbrecht steadied the ship with a 45-ball 40 before he was caught by Marco Jansen from Ottniel Baartman's delivery.

And with that, the Netherlands' scoring rate soon fizzled out, with the Dutch finishing on 103-9.

That lacklustre conclusion to their innings looked set to be swiftly forgotten as South Africa's top order disintegrated inside the first four overs, and the Netherlands seemed to be on their way to a famous win.

But a strong partnership of Tristan Stubbs (33) and Miller anchored South Africa's innings, and the Proteas emerged victorious with an over to spare.

Miller fittingly confirmed the victory with a six, smashing that shot through the leg side.

Sri Lanka remain bottom of Group D following their two-wicket defeat to Bangladesh earlier in the day. 

Meanwhile, Afghanistan continued their excellent start at this year's tournament, beating New Zealand by 84 runs to move top of Group C. 

Data Debrief: Dutch come unstuck

The defeat for the Netherlands ended their longest unbeaten streak in the competition, with the Dutch having won each of their last three matches at the T20 World Cup.

South Africa gained a measure of revenge, meanwhile, for their 13-run defeat to the Netherlands at the 2022 T20 World Cup.

Nepal looked on the verge of a shock victory, needing two from the final ball to secure the win. However, Ghulsan Jha was run out at the non-striker's end as South Africa came through unscathed to make it four wins from four at the tournament.

Despite Ottniel Baartman bowling the final over, it was Shamsi's 4-19 that proved crucial in South Africa getting over the line, including two wickets in the 18th over to turn the game back in his team's favour.

The spinner was thankful South Africa avoided an unlikely defeat, telling reporters: "[I am] definitely relieved.

"The team is standing up to the pressure and that's great to see."

Proteas captain Aiden Markram praised the efforts of Nepal, whose narrow defeat means they are eliminated from the competition with one game to spare in Group D.

"You have to give Nepal a lot of credit," Markram said. "Throughout the game they put us under a lot of pressure, and it shows the quality they have."

While Nepal skipper Rohit Paudel was disappointed in the defeat, he also took pride in how his team fared against one of the tournament favourites.

"I'm very proud of the unit, the way we bowled and batted," Paudel stated. "We were very close but a little far."
