Sparkling knocks from Aiden Markram and David Miller propelled South Africa to a five-wicket victory over India at the T20 World Cup.

The heavyweight nations put on a show at the Perth Stadium on Sunday, with Markram's 52 and Miller's unbeaten 59 seeing the Proteas claim a victory that moves them top of Group 2.

South Africa's bowlers had done a superb job of limiting India to 133-9 from their 20 overs, with Wayne Parnell (3-15) and Lungi Ngidi (4-29) in outstanding form.

Suryakumar Yadav's fantastic 68 ensured India had a sniff at defending a modest target, and their tails were up when Arshdeep Singh, the pick of India's bowlers with 2-25, dismissed Quinton de Kock and Rilee Rossouw in the second over.

With Temba Bavuma also falling, Markram had to get South Africa moving. His knock did not come without risk – he survived two run-out near misses and was dropped by Virat Kohli before his luck eventually ran out when he picked out Suryakumar in the deep.

Where Markram left off, Miller picked up, striking successive sixes to put South Africa in control.

Though India rallied to leave South Africa needing six runs from the final over, Miller held his nerve to get the Proteas over the line. 

Kohli's fumble proves costly

After dismissing Tristan Stubbs in his fourth and final over with the ball, Ravichandran Ashwin (1-43) is just two away from becoming India's third-highest wicket-taker in men's T20Is.

However, he really should have had a 69th T20I wicket earlier in the innings when Markram found Kohli at deep midwicket, only for the former India captain to fail to take the catch after a juggle. Markram was on 35 at the time, and went on to add a damaging 17, including a huge six, to push South Africa on.

Markram and Miller turn on the style

South Africa's pace bowlers would have been hard done by had they finished on the losing side, with Ngidi having dismantled India's top order before fellow quick Parnell chipped away at the tail.

Fortunately, Markram and Miller – who struck seven boundaries each – delivered to ensure the bowlers' work was not fruitless, with the latter stepping up to guide the Proteas home. South Africa have now won their last six completed T20 World Cup matches, a new national record.
