About ICC Cricket

Womens Cricket

The ICC Player Rankings are a sophisticated moving average. Players are rated on a scale of 0 to 1000 points. If a player’s performance is improving on his past record, his points increase; if his performance is declining his points will go down.

The value of each player’s performance within a match is calculated using an algorithm, a series of calculations (all pre-programmed) based on various circumstances in the match.

All of the calculations are carried out using pre-programmed formulae, using the information published in a Test match scorecard. There is no human intervention in this calculation process, and no subjective assessment is made.

Test Match Rankings

For a batsman, the factors are:

  • Runs scored
  • Ratings of the opposing bowling attack; the higher the combined ratings of the attack, the more value is given to the batsman’s innings (in proportion)
  • The level of run-scoring in the match, and the team’s innings total; an innings of 100 runs in a match where all teams scored 500 is worth less than 100 runs in a match where all teams were bowled out for 200. And if a team scores 500 in the first innings and 200 in the second innings, a century in the second innings will get more credit than in the first innings (because the general level of run scoring was higher in the first innings)
  • Out or not out (a not out innings receives a bonus)
  • The result. Batsmen who score highly in victories receive a bonus. That bonus will be higher for highly rated opposition teams (i.e. win bonus against the current Australia team is higher than the bonus against Bangladesh.)

For a bowler, the factors are:

  • Wickets taken and runs conceded
  • Ratings of the batsmen dismissed (at present, the wicket of Kumar Sangakkara is worth more than that of Makhaya Ntini – but if Ntini's rating improves, the value of his wicket will increase accordingly)
  • The level of run-scoring in the match; bowling figures of 3-50 in a high-scoring match will boost a bowler’s rating more than the same figures in a low-scoring match
  • Heavy workload; bowlers who bowl a large number of overs in the match get some credit, even if they take no wickets;
  • The result. Bowlers who take a lot of wickets in a victory receive a bonus. That bonus will be higher for highly rated opposition teams

Bowlers who do not bowl in a high-scoring innings are penalized.

The players’ ratings are calculated by combining their weighted performance in the latest match with their previous rating. This new ‘weighted average’ is then converted into points. Recent performances have more impact on a player’s rating than those earlier in his career, but all his performances are taken into account. A great player who has had a lean run of form will still have a respectable rating.

Players who miss a Test match for their country, for whatever reason, lose one per cent of their points.

New players start at zero points, and need to establish themselves before they get full ratings. There is a scale for calculating qualifications. For example, a batsman who has played 10 Test innings gets 70 per cent of his rating (i.e. his rating will be between 0 and 700 points). He doesn’t get 100 per cent until he has played 40 Test innings. A bowler who has taken 30 wickets also gets 70 per cent of his full rating. He doesn’t get 100 per cent until he has taken 100 Test wickets. This means that successful new players can enter the top 30 after just a few Tests, but are unlikely to reach the world top five until they have many Test matches under their belts.

One-Day Rankings

The principles behind the ODI Ratings are similar to those for the Test Ratings, with the following important differences:

  • Batsmen gain significant credit for rapid scoring. They only get a small amount of credit for being not out (because a not out batsman is, by definition, batting at the end of the innings when the value of his wicket is low)
  • Bowlers gain significant credit for economy. A bowler who bowls 10 overs 0-10 is likely to see his rating improve significantly, even though he hasn’t taken a wicket.
  • Players lose only a half per cent (½%) of their points for missing a match for their country.All ODI matches are considered equal, except for ICC Cricket World Cup matches, where good performances gain extra credit.Big scores or wicket hauls against very weak nations get much less credit than the same performances against the main ODI countries.

Women’s ODI Rankings

The Women’s ODI Rankings operate in the same way as the men’s equivalent.  However, statistically there are some differences between men’s and women’s ODI cricket, so there are some adaptations for the women’s version. The average scores in women's ODIs tend to be lower than in men's so the points scales were adjusted so as not to favour bowlers, and there are fewer women play ODIs in a given year than men, so there are typically more men bunched within a few points of each other in the table than in the women's equivalent.
