The ICC’s New Ball Rule and What It Means for 2027 ODI World Cup
Cricket is going through one of its biggest rule changes in over a decade. The International Cricket Council (ICC) has made a major change to how One Day Internationals (ODIs) are played. From July 2, 2025, ODI cricket will use only one ball in the final phase of each team’s innings, replacing the previous system where two brand new balls were used throughout the entire match.
This change has forced cricket teams around the world to rethink their batting plans, bowling strategies, and overall match tactics. With the ODI World Cup in South Africa coming in October-November 2027, teams are working hard to understand how this new rule will affect their game and help them prepare for the biggest tournament in the sport.
The Old System
For the past fourteen years, ODI cricket followed a rule where two fresh balls were used during an innings. One ball was used from one end of the pitch, and another brand new ball was used from the opposite end. This meant each ball stayed in play for only 25 overs before being replaced with a fresh one. This system was introduced in October 2011 to keep the cricket ball clean and hard for a longer time.
The New System
Starting July 2025, the game works differently. Teams still begin ODIs with two brand new balls, but only for the first 34 overs. Once the 34th over is completed, the bowling team gets to pick which of the two balls is in better condition. That selected ball is then used at both ends of the pitch for the remaining 16 overs until the end of the innings.
Why This Change Happened
The ICC made this change because cricket had become too tilted in favor of batters. Over time, batters were scoring too many runs while bowlers struggled to take wickets in the later stages of ODI matches. The governing body wanted to bring back something called “reverse swing” — a special bowling technique that had almost disappeared from ODI cricket.
Understanding the Older Ball
When a cricket ball gets older and is used for more than 34 overs, it changes significantly. The ball becomes softer, darker, and loses its shine. Most importantly, it becomes much harder to hit the ball far. The older ball does not bounce as high as a fresh ball, and it does not travel as far when hit by a batter.
This is where the new rule creates a major problem for batting teams. In the old system, batters in the final overs always had a relatively new ball to work with. They could attack freely and hit big shots more easily. Now, with the same worn ball being used at both ends from the 35th over onwards, batters face a much tougher task in scoring quick runs.
What Teams Are Learning
India’s batting coach Sitanshu Kotak has been open about the challenges. He explained that teams need to create new batting plans specifically for this change. “We will have to adjust in the batting department. We have to try to set up one template based on how we play after this new rule,” he said during recent matches.
The difference becomes clear from the 42nd over onwards, when the ball has been in play for many overs. This is where batting becomes much harder. Teams now face a choice: score aggressively earlier in the innings when the ball is fresher, or wait and face a tougher old ball later.
What is Reverse Swing?
Reverse swing is a special bowling skill that had almost disappeared from ODI cricket under the old two-ball system. This technique happens when a cricket ball becomes old and worn, typically after 30 to 40 overs of use. The ball develops a scuffed, rough surface on one side while the other side remains polished and smooth.
When a fast bowler throws this older, roughed-up ball at very high speeds (above 80 miles per hour), something interesting happens. The rough side of the ball creates more air resistance than the smooth side. At these high speeds, this causes the ball to swing in the opposite direction from what batters expect. The ball moves toward the rough side instead of the smooth side, which is the normal swing direction.
Why Bowlers Lost This Skill
With the old two-ball rule, reverse swing was nearly impossible in ODI cricket. Because each ball was only used for 25 overs before being replaced with a fresh ball, the ball never got old enough to develop the rough surface needed for reverse swing. The fresh ball would simply not have the wear and tear required to produce this effect.
This gave batters a big advantage. They knew the ball would always be relatively new and fresh, making it easier to score runs in the death overs. Reverse swing bowling, which had been an important skill for bowlers in Test cricket and historical ODIs, became useless in modern 50-over cricket.
Bringing Back a Lost Art
The ICC’s new rule allows the ball to be used for 16 overs (from the 35th to 50th over) after having been in play for 34 overs already. This gives the ball time to wear down and develop the conditions needed for reverse swing. Bowlers can now use this skill to surprise and deceive batters in the crucial final overs of an innings.
This is a major shift that helps restore balance to the game. Fast bowlers who master reverse swing can now be highly dangerous in the death overs, even when batters are trying to score maximum runs. This brings back excitement and challenge to ODI bowling.
Preparing for 2027
With the ODI World Cup in South Africa less than two years away, teams are racing against time to master these new conditions. The South African pitches are known for favoring pace bowling and higher bounce. When combined with an older, worn ball, the bowling attack could be particularly dangerous.
Indian players, especially those who grew up with the old ball system, have a potential advantage. However, all teams are working hard to understand and adapt to these changes. The team that masters the new batting and bowling strategies fastest will likely have a significant edge when the World Cup arrives.
The Balance Between Bat and Ball
This rule change represents an effort to restore balance in cricket. For many years, experts and former players had complained that ODI cricket had become too easy for batters. Sachin Tendulkar, one of cricket’s greatest batters, had called the two-ball rule “a perfect recipe for disaster” because it prevented bowlers from using reverse swing.
The ICC’s decision to change the rule shows that the sport’s leadership listened to these concerns. By bringing back the ability to use older balls in the final overs, the game becomes more challenging and interesting for both batters and bowlers.
As the sport moves toward the 2027 ODI World Cup in South Africa, this change will shape how teams prepare, how players develop their skills, and ultimately, how the game is played. Cricket is changing, and teams that understand and adapt to these changes will find success. The ones that stick to old methods may find themselves left behind in this new era of cricket.
