The South Africa vs Australia ODI series has already been decided, but the third and final match at JB Marks Oval in Potchefstroom still offers plenty for both sides to take away.
Australia head into Wednesday’s encounter after suffering two defeats in the opening matches, while South Africa have taken control of the series with impressive performances at Kingsmead and the Wanderers. With the contest already settled, the final ODI may lack the pressure of a series decider, but it provides an important opportunity for fringe players to make an impression.
The biggest question could be whether the weather allows the game to run its full course. Thunderstorms are forecast for the afternoon, potentially creating another complication for a match that is already expected to feature several changes.
South Africa Have Controlled the Series
South Africa have been the more consistent side throughout the first two ODIs, winning in contrasting conditions and finding important contributions from both their established players and supporting cast.
Their success has also highlighted an unexpected storyline. Instead of their traditionally feared pace attack dominating proceedings, spin has played a major role. Turning pitches have allowed South Africa’s slower bowlers to exert pressure, while Australia have struggled to consistently handle left-arm spin.
The batting numbers have also favored the hosts. Matthew Breetzke, Temba Bavuma and David Miller have all produced centuries during the series, while Australia have yet to register a three-figure score.
With the series already secured, however, South Africa are unlikely to take unnecessary risks with players who are also expected to feature in the upcoming Test series beginning on October 9.
Can Potchefstroom Change the Pattern?
The move to JB Marks Oval could provide Australia with a different challenge.
Potchefstroom has generally produced productive batting conditions in recent years. Only three teams have been bowled out in the five completed day-night ODIs played at the venue, suggesting that batsmen can enjoy themselves when they settle in.
However, Australia will not need to look far back for a warning.
In September 2023, Australia were dismissed for 227 while chasing a target of 339 at this ground. South Africa used spin effectively during that match, with Aiden Markram, Tabraiz Shamsi and Keshav Maharaj combining for 4/99 from 21 overs.
The seamers claimed another five wickets, although they conceded at a significantly higher rate. That history could encourage Australia to attack the South African spinners more aggressively this time around.
The venue has also witnessed some huge totals. South Africa's highest score at JB Marks Oval is 418/5, although that innings came two decades ago against Zimbabwe. Two other first-innings totals above 300 have been recorded in the five completed day-night matches at the ground, with South Africa winning each of those games.
Potchefstroom's Sporting Connection
Potchefstroom may not be one of South Africa's biggest cities, but it has developed an interesting reputation as a preparation base for elite sporting teams.
Australia used the town as their base while preparing for the 2003 Cricket World Cup, a tournament they ultimately won. Spain's football team also prepared in the area before winning the 2010 FIFA World Cup.
The attraction is relatively simple. Potchefstroom offers fewer distractions than a major city, giving athletes an environment centered around training, recovery and competition.
That could make the venue particularly suitable for a final ODI in which both teams are likely to experiment with personnel and combinations.
Weather Could Become the Biggest Factor
The biggest threat to Wednesday’s match may come from above rather than either team.
A major thunderstorm is forecast during the second innings, while around 11.7 millimetres of rain had been predicted for Tuesday. Any significant rainfall could leave the outfield slower and potentially affect the pace and timing of the game.
For Australia, interruptions would be particularly frustrating because the match represents another chance to assess players before future major assignments. South Africa, meanwhile, will want to give their reserve players valuable international exposure without risking members of their Test squad.
If the rain stays away, conditions should provide an opportunity for a high-scoring encounter.
South Africa Team News
South Africa are expected to rotate their squad for the final ODI.
Nqobani Mokoena is the only member of the squad who has not featured in either of the opening two matches, making him a strong candidate to receive an opportunity.
Head coach Shukri Conrad also indicated that selections would be carefully managed, particularly because several players are involved in the upcoming Test campaign.
Possible South Africa XI
Tony de Zorzi, Quinton de Kock, Ryan Rickelton, Matthew Breetzke, Tristan Stubbs, David Miller, Duan Jansen, Keshav Maharaj (captain), Bjorn Fortuin, Lizaad Williams, Nqobani Mokoena
The final XI could therefore contain a mixture of experienced international players and less-established members of the squad.
Australia Team News
Australia are also expected to make changes.
Pat Cummins was originally expected to play his first match of the series in the previous ODI but did not feature. He could now return for the final game, potentially replacing Nathan Ellis, who is unavailable because of a side strain.
Mitchell Marsh could continue as captain, while Oliver Peake may finally receive an opportunity after waiting on the sidelines. Jack Edwards is doubtful because of a hamstring problem.
Possible Australia XI
Mitchell Marsh (captain), Travis Head, Cooper Connolly, Alex Carey, Matt Renshaw, Cameron Green, Oliver Peake, Xavier Bartlett, Pat Cummins, Mitchell Starc, Adam Zampa
For several of these players, the match will be less about the series result and more about making a case for future selection.
Fringe Players Have Plenty to Prove
With the series already decided, South Africa's Keshav Maharaj highlighted the importance of opportunities for players on the fringes of the squad.
The final ODI could therefore be particularly significant for those looking to demonstrate that they can handle international cricket when called upon.
Australia's Matt Renshaw is approaching the match from a similar perspective. Rather than focusing solely on the outcome of the current series, he has already turned his attention toward learning from the opposition and preparing for future World Cup challenges.
That mindset could make the final match more competitive than the phrase "dead rubber" suggests.

What to Expect
The series may already belong to South Africa, but the third ODI still carries significance for individual players and future team combinations.
South Africa will want to maintain their momentum while managing the workload of players preparing for the Test series. Australia, meanwhile, have an opportunity to respond after two disappointing defeats and give several squad members valuable international experience.
The conditions could also make this an intriguing contest. Potchefstroom has traditionally offered plenty of runs, while South Africa's spin attack has been one of the defining features of this series.
Then there is the weather.
If thunderstorms disrupt the second innings, the match could become a shortened and unpredictable contest. If the rain stays away, the batting-friendly venue could give Australia the opportunity to finally produce the performance they have been searching for.
A dead rubber may not decide the series, but it can still decide who makes the most of their opportunity.
