Which has been the best era for batting in Test cricket's history?

And when have bowlers dominated? Over 2500 Tests have been played so far – we analyse the numbers

S Rajesh02-Jun-2023The Wellington Test between New Zealand and Sri Lanka earlier this year – which the home team won by an innings and 58 runs – was the 2500th Test match in men’s cricket. It wasn’t a particularly memorable contest, but the landmark was a reminder of how long the format has been around.The very nature of the five-day game means only a limited number of them can be fitted into an annual calendar. In 2022 only 43 Tests were played, compared to 161 ODIs and a whopping 531 T20Is (that last number is also a function of the huge number of teams that play the shortest format). While it has taken 146 years for Test cricket to reach 2500 matches, the other two formats have been rapidly adding to their numbers: in 52 years of the 50-over ODI, 4578 matches have taken place, while 2076 T20Is have been played in only 18 years.That by itself means milestone matches come far less frequently in Tests. The 2000th Test was played almost 12 years ago, in July 2011, and the 1500th about 11 years before that. And that is super quick compared to the first 500, which took 83 years. (Even accounting for the 11 years lost to the two world wars, that’s a long time.)So how has Test cricket changed in this period, and which teams and players have been the most dominant in each of the five non-overlapping 500-Test blocks? Let the numbers tell the story.

Overall numbers in Test cricket, 1877 to 2023

For a format that has been played for more than 145 years, it is remarkable how similar the batting averages are in the five blocks. The early part of the first block featured lower averages due to uncovered pitches, but since then the number has hovered around the early 30s. The averages in the third and fifth blocks vary from each other by a minuscule 0.01, while in the second block (1960-1984), it was only about half a run higher.ESPNcricinfo LtdIn the first decade of the 2000s, the overall batting average jumped to almost 35. That was clearly the batting era, characterised by relatively flat pitches, several batters who averaged above 50, and bowlers who struggled to achieve sub-30 averages. That is the only block of 500 Tests in which more than 1000 centuries were scored – 1042, compared to 766, 854, 791 and 951 in the four other blocks (in chronological order). Since then, bowlers have fought back to re-establish equilibrium, and in the last five years, they have even turned the tables on the batters.What changed, though, are scoring rates, and the number of non-draw results. From a dour 2.54 runs per over in the first block, the run rate has gone well past three now, which seems to be the influence of the 50- and 20-over formats. That’s the one data point where the number has consistently gone up in every period, apart from the last decade, when it dipped marginally in comparison to the previous one, largely due to the more bowler-friendly conditions on offer. The percentage of draws has drastically decreased too, from around one in every two games in the second block of 500 Tests, to one every five games in the last decade.

Team-wise trends in each 500-match block of Test cricket

To start with, England and Australia were the dominant teams. Of the first 500 Tests, in 178 those two teams were pitted against each other, while 310 involved at least one of them. South Africa were the only other team to play more than 100 Tests in this period. However, while Australia and England won many more Tests than they lost, South Africa largely struggled in this period, winning only 27 against 72 defeats.
