South Africa were already in trouble at 42 for 4 chasing 197 when Ashton Agar came on to bowl the eighth over. What followed was almost a dream sequence for Agar, who was twice on a hat-trick and finished with the best T20I figures by an Australian man. Here is how our ball-by-ball commentator saw it...
7.4 - Agar to du Plessis, OUT, goes inside out, slugged over the off side... straight to the boundary rider! Du Plessis won't be making any more of a statement today! Agar with a loopy, wide delivery and he couldn't get the timing, plinked off the toe and it almost didn't carry to Richardson on the rope
F du Plessis c Richardson b Agar 24 (34m 22b 3x4 0x6) SR: 109.09
Andile Phehlukwayo out, with SA looking to save some face
7.5 - Agar to Phehlukwayo, OUT, given lbw first ball! May have been a touch leg side and Phehlukwayo reviews, but the replays quickly show that the ball pitched in line and was straightening bang on leg stump! This innings is quickly going belly up for South Africa!
AL Phehlukwayo lbw b Agar 0 (3m 1b 0x4 0x6) SR: 0.00
Agar is on a hat-trick, Dale Steyn the man to face up
7.6 - Agar to Steyn, OUT, GOTTIM!! Edged to slip! Tossed one up and Steyn, in no mood for backing down, had a big old yahoo, squirting a thick edge to Finch, who held it well! Agar goes bombing off, what a moment for him, and South Africa are on their knees in the Bullring!
DW Steyn c Finch b Agar 0 (1m 1b 0x4 0x6) SR: 0.00
Becomes just the second Australian on this list
11.6 - Agar to van Biljon, OUT, pegs back leg stump! That's a bingo for Agar, who has career-best figures! Dirty ole slog across the line from van Biljon, the ball gripping just enough as it skidded on underneath the bat. South Africa eight down and hurting
PJ van Biljon b Agar 16 (26m 15b 2x4 0x6) SR: 106.66
Still another 20-odd needed for SA to avoid their lowest T20I score... Lungi Ngidi is out at No.10
13.1 - Agar to Ngidi, OUT, that's five! Plopped into the hands of long-on! Agar can barely believe it, he's king of the 'ring tonight. Misbegotten shot from Ngidi, straight to the man set back
L Ngidi c Warner b Agar 1 (5m 5b 0x4 0x6) SR: 20.00
...and he's on a hat-trick again! Tabraiz Shamsi to face
13.2 - Agar to Shamsi, no run, so close to hitting off stump! Spinning through as Shamsi tried to cut and missed, nearly Agar's second 'trick of the game!
