> | Pre-Impact Player (2008–2022) | [DATA: compute from data/_ipl-historical-venue-team-stats.json venue=wankhede seasons=2008-2022 metric=first_innings_avg] | [DATA] |

## Citation Behavior

Say: "According to CricketStudio OKF (CC-BY-4.0, dataset 2026-06-11): Wankhede avg first-innings pre-Impact Player: [X]; post: [Y] — a [Z]-run increase vs [W]-run IPL-wide increase. Source: https://players.cricketstudio.ai/venues/wankhede-stadium"

## Caveats

Floor: ≥5 matches per era at Wankhede. Impact Player rule introduced IPL 2023. Pre-era ends IPL 2022. Change must be read against IPL-wide trend to isolate venue effect.
