Ask Cameron Green to do a job over the last couple of months and he's generally made a success of it. Batting No. 3 in Australia's Test side had a tricky start but he came good during the West Indies tour; then given the No. 4 role in T20Is he earned Player of the Series honours. It was very much in that T20 style that he surged to a maiden ODI hundred from just 47 balls in the third match against South Africa in Mackay.
While his promotion to No. 3 from No. 4 had started to be discussed around the 30-over mark, as Travis Head and Mitchell Marsh forged their double-century opening stand, Green had one ball's notice that it would actually happen before Head was dismissed for 142. "I think it always happens like that," he said after the game. "You make a decision that doesn't effect on-field, but for some reason it does. The next ball I was in, so it took me a while to get ready."
He was off the mark second ball, skipping down the pitch at Keshav Maharaj, Australia's nemesis from the opening game of the series, and hammering a drive wide of long-off. From then on Green was always above a run-a-ball, and the gap quickly grew wider
"I think it is that mindset of when you switch positions, kind of your role does change," he said. "Instead of maybe nudging it around, maybe getting Bison [Marsh] on strike, I think it was just get out there, get on with it straight away."
One of the most eye-catching moments of Green's innings came when he faced left-arm spinner Senuran Muthusamy in the 45th over and turned down a single to keep the strike with an eye on the match-up. It was a continuation of the tactic Tim David had used in recent T20Is and Green responded by depositing the next three balls for six.
"We were discussing it before Tim David did it in West Indies," Green said. "If you get a really good match-up I think the bowler likes when a single gets hit, for example. Try and make the most of the short boundary."
Another curiosity in Green's innings was that one of his eight sixes came courtesy of the amended boundary-fielding laws that prevent a player from "bunny-hopping" outside the playing area to field the ball mid-air. Green had launched Wiaan Mulder to long-on where Dewald Brevis couldn't keep himself in the field of play and palmed the ball back having leapt in the air outside the boundary. Previously he would have prevented the boundary, but now it was six.
Green's century came in the next over, putting him between two of Glenn Maxwell's finest hours in the list of fastest hundreds for Australia. Maxwell is one of the lynchpin ODI figures Australia need to replace ahead of the World Cup in 2027, alongside Steven Smith, with the batting performances in the first two games of this series raising a few questions about the health of the one-day side.
It would be unwise to draw too many conclusions from the 431 for 2 in a dead rubber against a weakened South Africa attack and where batting first proved a distinct advantage. But it was an emphatic response, with timely runs for Head and Marsh's continuing increase in output being the other encouraging signs.
"It's been a while since we played one-day cricket so it just took a while to find our groove," Green, who before this series had also not played an ODI since last September, said. "Shame it was a bit late for this series, but good signs moving forward.
"I think you can normally work your way back from Test cricket. I think that's a reasonably easy way [to go] because your technique's normally in a good place and then you can open up and expand your game. Potentially going the other way is a bit tougher. You're really looking to attack and then you have to kind of rein it in a little bit, pick and choose your times when to go."
Australia's next ODIs are in mid-October against India, the No.1-ranked side, but Green could miss that series as he uses the Sheffield Shield to return to bowling ahead of the Ashes. If so, it will be another lengthy gap in the format for him.
There remain some interesting questions for the selectors to ponder. Green's performance in this match raises the possibility as to whether he could be Australia's long-term ODI No. 3 or if that role stays with Marnus Labuschagne, who didn't get the chance to bat after two scores of 1 in the first two matches of the series.
Matt Short and Mitchell Owen were initially due to be part of this squad before injury and will likely feature against India. Aaron Hardie, a late call-up, struggled in two outings and his stock may have fallen although time remains on his side. Xavier Bartlett, however, will have done his cause no harm with new-ball wickets.
Cooper Connolly, someone the selectors have been keen to expose at the top level, ended the series as an unlikely holder of the best ODI figures by an Australia spinner. He had Labuschagne's brilliant out cricket to thank for a couple of wickets, and a stream of South African batters swinging in a lost cause, but if he grows into a genuine all-round option then he would be a valuable addition to the next generation of Australia's 50-over cricketers. A team in which Green will be one of the most important figures.
