Day-Night Test Cricket: Pink Ball at Eden Gardens 2019 — How D/N Tests Changed the Format
The first Day-Night Test match was played between Australia and New Zealand at Adelaide Oval on 27–29 November 2015, using a Kookaburra pink ball under floodlights. India played their first Day-Night Test vs Bangladesh at Eden Gardens, Kolkata on 22–24 November 2019. India won by an innings and 46 runs in less than 3 days. The pink ball moves more under floodlights due to atmospheric conditions (dew) and behaves differently from the red ball — faster in the early session, then more seam movement under lights. As of 2025, 27 Day-Night Tests have been played.
The first Day-Night Test match was played between Australia and New Zealand at Adelaide Oval from 27–29 November 2015 — a landmark in Test cricket that introduced the pink ball and floodlit Test matches to reach a broader television audience (evening viewers). Australia won by 3 wickets in the first day-night Test.
India's First D/N Test: Eden Gardens 2019
India played their first Day-Night Test against Bangladesh at Eden Gardens, Kolkata, from 22–24 November 2019. The match attracted approximately 50,000 fans per day — the largest Day-Night Test attendance in history. India won by an innings and 46 runs in less than 3 days; Bangladesh were bowled out for 106 and 195. Ishant Sharma took 5/22 in the second innings. The match confirmed that Day-Night Tests in Indian venues could draw significant crowds, building the commercial case for wider adoption.
Pink Ball Behaviour
The pink ball behaves differently from the red ball under floodlights: (1) The pink coating remains more visible under lights but wears faster — the lacquer erodes by overs 20–30, after which the ball seams more and loses swing earlier than a red ball. (2) Dew from evening conditions makes the ball wet and difficult to grip from overs 40–50, reducing spin and reverse swing — a structural advantage for batters during the twilight session. (3) Atmospheric conditions under lights generate more conventional swing in the powerplay (first 20 overs) than a red ball in similar daylight conditions. As of 2025, 27 Day-Night Tests had been played, with bowlers on first-innings batting teams winning 63% of matches — higher than the 56% rate in daytime Tests.
Frequently asked questions
Why does the pink ball move more than the red ball under floodlights, and what atmospheric physics explains the increased seam movement in the twilight session?
Pink ball physics under floodlights: the additional movement of the pink ball is not purely a property of the ball itself but an interaction of ball properties with atmospheric conditions. The specific mechanisms: (1) Lacquer composition: the pink lacquer used to coat the pink ball (initially by Kookaburra, later Dukes) has a different chemical structure to red lacquer. Red lacquer is oil-based and more resistant to atmospheric moisture. Pink lacquer (designed for visibility) is more water-absorbent — it absorbs surface dew faster and changes the ball's weight distribution subtly in the twilight session. (2) Twilight air density: as the ambient temperature drops from day to evening (typically 5–10°C at Adelaide), air density increases by approximately 1.5%. Denser air provides more resistance to the ball in flight, enabling swing to persist at slightly lower seam positions. This is the same physics as a cricket ball swinging more in England (cooler, denser air) than in the subcontinent (warmer, lighter air). (3) The dew factor: once significant dew appears (typically from overs 35–50 in the second session), the ball becomes heavy and slippery — reducing all bowling skill (less grip for spin, less control for seam) and benefiting batters. The structural consequence: Day-Night Tests produce a 'bowling window' (overs 1–20, when the lacquer is fresh, humidity is high and dew is absent) and a 'batting window' (overs 30–50 when dew sets in). Teams winning the toss tend to bowl first to exploit the bowling window, which explains the higher win rate for bowling-first teams in D/N Tests.
