They hit him, sledged him and bounced him. But ultimately, all they could do was applaud him.
South Africa were powerless to halt Australian captain Michael Clarke continuing his unprecedented run-scoring spree.
Clarke became the only batsman in Test history to pass 200 four times in a calendar year with a stellar 224 not out against the Proteas on Thursday's opening day of the second Test in Adelaide.
He arrived at the crease with Australia wobbling, having lost three wickets in 15 balls.
But, with David Warner (119) and later Mike Hussey (103), Clarke delivered audacious counter-punches which floored the best Test team in the world.
Clarke has made 1265 Test runs this year at the jaw-dropping average of 140.55.
Since being appointed Australian Test skipper in mid-2011, Clarke has made 1838 runs at 79.91.
His leadership tenure has featured a triple-century, three double-centuries, and three plain-old tons.
Only five Australians have made more Test runs in a calendar year than Clarke - and he has a maximum seven Test innings to come.
If Clarke's rich form vein continues, he could surpass Ricky Ponting's Australian record for most runs in a calendar year - Ponting made 1544 in 2005.
And given his penchant for turning centuries into doubles and triples, even the world record of Pakistani Mohammad Yousuf (1788 runs in 2006) is threatened.
In Adelaide on Thursday, Clarke was sconned on the helmet by Proteas' paceman Dayle Steyn early in his knock.
The South Africans made good their pre-match promise to pepper the Aussie skipper with short balls.
Steyn aimed a few choice words at Clarke, but the Australian let his bat reply.
He has 21 Test tons and averages more than 50 - the mark considered to confirm greatness.
Clarke and Hussey produced an extraordinary burst of batting to put Australia in a dominant position against a badly-wounded South Africa on day one of the Second Test.
Clarke scored a single off spin bowler Imran Tahir to bring up his 200, with Hussey smashing a six off the very next ball to score his century and keep the Adelaide Oval crowd on its feet.
Australia was in total control at stumps, having scored a massive 5/482.
Clarke surpassed Sir Donald Bradman and Ponting, who both recorded three 200-plus scores in a year.
Clarke's 224 not out is the most runs in a Test day by any player in Australia, beating Bradman's 223 in 1931.
Hussey was bowled by Dale Steyn for 103 to finish the day's play.
