IPL's Biggest Scoring Jump Happened the Season Impact Player Arrived
June 23, 2026 · CricketStudio · How to cite
1The Finding
IPL 2023 — the season the Impact Player substitution rule launched — saw scoring jump 9.3 runs per innings (155.8→165.1), the largest single-season rise in the 18-year corpus.
2What the Numbers Show
| Metric | Value | Sample / Context |
|---|---|---|
| IPL 2022 avg (last pre-Impact season) | 155.8 runs/innings | No Impact Player rule |
| IPL 2023 avg (first Impact season) | 165.1 runs/innings | +9.3 — largest single-season jump in corpus |
| IPL 2024 avg | 173.6 runs/innings | +8.5 from 2023 — second largest jump |
| IPL 2025 avg | 171.0 runs/innings | Third consecutive above-165 season |
| Post-Impact avg (2023–2025) | 169.9 runs/innings | 3 seasons; pre-Impact Era 3 avg ~155.5 |
| All-time highest before 2023 | ~158 runs/innings | No prior season exceeded 160 |
3Why It's Surprising
The Impact Player rule — which lets teams deploy an 11th specialist who can substitute in after the powerplay — was designed for tactical flexibility, not to boost scoring. Yet the three seasons after its launch (2023: 165.1, 2024: 173.6, 2025: 171.0) are the three highest-scoring IPL seasons in 18-year history. The 2022→2023 jump of 9.3 runs exceeds every prior single-season rise in the corpus. Whether the rule caused the surge or coincided with a broader power-hitting revolution is contested — but the timing is precise: the last pre-Impact season (2022: 155.8) and the first with it (2023: 165.1) mark the sharpest scoring boundary in IPL history.
