ICC ODI and T20I Rankings: Methodology, Differences, and Current Leaders
How ICC ODI and T20I player rankings are calculated differently from Test rankings, why weighting varies across formats, and what the rankings reveal about the best limited-overs cricketers in the world.
The ICC maintains separate player ranking systems for ODI (One Day International) and T20 International cricket, each calibrated to the demands and statistical norms of their respective format. While the underlying philosophy — assigning numerical ratings that update after each match based on performance relative to opponent quality — is shared across all three formats, the specific weightings, decay rates, and qualifying thresholds differ materially between Test, ODI, and T20I rankings. Understanding these differences explains why a player can be ranked highly in one format while appearing much lower in another.
ODI Rankings: Adjusted for Run Rate and Match Context
ODI rankings weigh both volume (runs scored or wickets taken) and efficiency (run rate, economy rate, strike rate relative to the innings phase). A batter who scores 90 off 80 balls in the Powerplay earns different rating points than one who scores 90 off 130 balls at No.7 in the death overs, even though both have contributed 90 runs. This phase-weighted approach attempts to capture batting value more accurately than a raw run count. Similarly for bowlers, economy rate across different powerplay and death-over phases contributes to the rating alongside wicket count. The opponent-strength adjustment still applies: defeating Bangladesh's bowling attack for a century carries less rating credit than an equivalent performance against England or South Africa. ODI rankings have a somewhat faster decay rate than Test rankings, reflecting the higher frequency of matches (most teams play 20–30 ODIs per year versus 10–15 Tests).
T20I Rankings: High Decay Rate and Strike Rate Premium
T20I rankings update most frequently and use the fastest decay rate of all three formats, reflecting both the volume of international T20 cricket (which has expanded dramatically since 2020 with events like the ICC T20 World Cup and bilateral series) and the high variance inherent in the format. A single T20 knock of 80 off 40 balls can cause significant rating movement; conversely, a string of moderate performances below 30 can drop a batter several places in a short period. Strike rate is a primary component of T20I batting ratings: a batter averaging 40 at a strike rate of 120 will typically be rated lower than one averaging 35 at a strike rate of 160, because the T20I format rewards boundary-hitting and risk-taking above average protection. For bowlers, the T20I rankings place greater emphasis on economy rate (runs conceded per over) than on wicket count alone, since containing batters during the final five overs of a T20I is a scarce and valuable skill. The ICC has occasionally reviewed whether a single all-format ranking (superseding separate format tables) would be useful, but the distinct skill sets required across formats make this a problematic exercise.
Frequently asked questions
Why do some players rank very differently across the three ICC formats, and what does this tell us about their skills?
Large discrepancies in a player's rankings across Test, ODI, and T20I cricket are among the most revealing data points in the sport. They expose the degree to which a player's core skills align with the demands of each format — and where they do not. The most common pattern is a player who excels in Test cricket but ranks much lower in T20Is. This typically describes a classical batter who builds innings patiently, rotates the strike with singles and twos, and accumulates runs over long periods — precisely what Test cricket rewards. The same traits become liabilities in T20 cricket, where 120 balls is the entire match, and a batter who takes 30 balls to get in before accelerating is consuming too great a proportion of the team's resources in the setup phase. Joe Root is an instructive example: routinely among the top two or three in Test batting rankings, his T20I contributions have been modest because his natural game requires time and conditions that T20 cricket does not provide. Conversely, explosive batters built for T20 cricket — those with exceptional power, hand-eye coordination for unconventional shots, and the mental wiring to attack from ball one — often rank lower in Tests. The patience required to bat for four sessions on a seaming English pitch, the technical discipline of leaving the ball outside off stump, the mental resilience of rebuilding after surviving an early chance: these are developed skills that power hitters may not have been required to cultivate in franchise T20 leagues. Some players genuinely bridge the formats. Virat Kohli at his peak was ranked No.1 in both ODI batting and was among the top three in Test batting — an extraordinary achievement reflecting his combination of technical correctness (for Tests) and aggressive efficiency (for ODIs). Babar Azam similarly reached No.1 in ODI and T20I batting simultaneously, reflecting a classical technique that translates across formats through sheer consistency of timing and placement. For bowlers, the format ranking gaps are even wider. A Test specialist who bowls long, probing spells at 75% of maximum pace, targeting the corridor of uncertainty outside off stump, will struggle in T20 cricket where batters attack anything full or short without concern for their wicket. Death-over T20 specialists who can bowl wide yorkers and back-of-a-length deliveries under extreme pressure are a specialist art form rarely required in Test cricket. The separate ranking systems for each format capture these differences accurately and are worth examining together rather than in isolation when evaluating a player's true range of ability.
