Irresistible Harmer the architect of Australia's destruction

After Simon Harmer threatened to strike with every ball on a dominant day five in Cape Town, it's hard to believe he took 170 balls to register his first wicket in the series.

Across the first Tests in Durban and Gqeberha, Harmer's biggest impact on the contest against Australia were his batting and fielding (82 and several sharp catches at St George's Park). He took time to get into the series with the ball; 28.2 overs in fact before finally dismissing first-Test centurion Matt Renshaw.

But come the decider at Newlands, the skill and local knowledge of the veteran off-spinner came to the fore with match-defining fourth-innings figures of 6-16.

He ran through four of Australia's middle-order batters in the space of 11 overs and his celebratory delirium - arms stretched wide, charging towards the boundary - was matched only in enthusiasm by the raucous Saturday crowd.

Harking back to the pure euphoria displayed by SA spinner of yesteryear Imran Tahir, each of Harmer's wickets prompted a short sprint to nowhere in particular, each more passionate than the last. Such were the regularly of these sudden bursts of speed, they appeared to inspire one young local fan to make his own mad dash across Newlands shortly after the Test had been won.

"For me watching him bowl, it's like when 'KG (Rabada) is on a heater. You think every single ball he can take a wicket,' Marco Jansen said of Harmer post-play.

Coming into this Test, Harmer's bowling figures for the series read four wickets at 72.75. Five days later, he emerged with his maiden 10-wicket haul in Tests and player-of-the-match honours.

He bowled closer to the stumps than his opposite number Nathan Lyon and slower too. Harmer had found the recipe to make the Newlands pitch play like a minefield.

"He works in angles, he works in lengths, he adjusts to the batter," Jansen said. "He's incredible with the ball … I'm very chuffed for him and he deserves the wickets he got."

Harmer's bold mid-match prediction that 120 would be a defendable score proved correct, as Australia folded for 111 in 57.1 overs.

"As a spinner on a turning wicket, that's what dreams are made of," Harmer told SuperSport after South Africa's 176-run win.

"To be able to bowl in that situation, guys around the bat, the theatre, creating pressure, it goes a really, really long way and it makes my job a lot easier.

"Today was a hell of a lot of fun. It's been a tough few weeks, but we'll enjoy tonight."

Temba Bavuma said the call of leaving out his close friend Keshav Maharaj in favour of Harmer as "one of the toughest calls" of his career. It was a gutsy but necessary decision after Harmer out-bowled South Africa's most prolific Test spinner in a heavy defeat at Kingsmead three weeks earlier. And the 37-year-old was up for the task as his country's No.1 spinner.

He toiled for Bavuma when the wickets offered little, bowling 156 overs for the series, 47 more than the next-most Lyon.

Harmer's day-five efforts came just a day after Lyon took 2-101 from 44 overs, as South Africa recovered from 4-140 and a lead of 40 runs to setting Australia 288 for victory.

Australia captain Pat Cummins suggested it was not necessarily fair to compare the two figures, and insisted his off-spinner had bowled well with the series on the line.

"It's a hard one. There's obviously a little bit of help being day five," Cummins said after Australia's 176-run loss. 

"I thought Nathan controlled the game really well. There are days where he goes and takes five or six wickets, but one of the big keys to why we love him on our side is that it makes everything else function well. 

"For most of the game, they went at 2.5 (runs) an over. We were really controlling that, and Nathan was the key to that."

But when presented with a rapidly deteriorating Cape Town surface, Harmer went from role player to world class.  He took the final six wickets of Australia's innings, further enhancing his incredible record in the fourth innings of matches.

Harmer has now bowled six times in the final innings of a Test and taken 25 wickets at an average of 6.96. South Africa have won all six of those matches.

That includes victories over India, West Indies, Bangladesh and now Australia, both at home and away.

For players who have taken at least 25 wickets in fourth innings, Harmer sits far ahead of the next best, all-time greats Bishan Bedi and Sir Richard Hadlee.  

The importance of his first-innings haul (4-104) shouldn't be discounted either, playing a crucial role in limiting Australia's lead to only 100.

He dismissed the ominous Travis Head (41) and out-of-sorts Marnus Labuschagne (0) in the same over and later returned to dismiss both set batters Josh Inglis (102) and Alex Carey (80) within a couple of overs of one another.

But the Cape Town Test will be remembered for Harmer's gigantic impact on the final day as he accumulated Australian wickets as freely as the Newlands patrons collected empty red cups on the ground's eastern 'Oaks' hill.
