Big hitters shine as unstoppable Indian Premier League begins

The 18th Indian Premier League has begun with a bang. Although not as big a one as the very first  match in 2008, when Brendon McCullum smashed an unbeaten 158 off 73 deliveries in a total of 222 for Kolkata Knight Riders, it has generated some powerful batting displays. In the first five matches, an average of 208.7 runs has been scored per innings in the first five matches; in 2008, it was 152.

In the last three years, the average has increased year on year from 165 in 2022 to 173 in 2023 and 175.5 in 2024. On the limited evidence available, this looks set to rise again in 2025.

Various explanatory variables have been suggested. One is the preparation of pitches which are conducive to batting. Second is the increase in so-called matchups, in which batters target individual bowlers. This is based on a level of analysis and data not available in the IPL’s early years. Amongst many outputs, current levels of analysis identify which bowlers are most vulnerable to being hit by particular batters.

Thirdly, an expansion of teams in 2022 from eight to 10 may have caused a dilution in the quality of the player pool. The tournament rules that each squad can have a maximum of 25 players, of whom no more than eight can be overseas. In a playing 11, no more than four can be overseas players. The addition of two teams created a demand for more Indian players and it is a commonly held view that the pool of bowling talent in India is not as deep as the batting pool.

A fourth variable is the introduction of an impact player in 2023. Each team is allowed to make one substitution throughout a match. In terms of team selection, a specialist batter can be played and then substituted by a bowler, who can bowl a full quota of overs, or
