Last week, the MCC announced plans to spend £200m upgrading Lords', with some of the money used for floodlights. However, a new paper suggests the latter might not be money well spent.
This is because day-night games are a poor competition. The authors looked at the 649 one-day day-night internationals played between 1979 and 2005, and found that the toss is massively important in such games.
They estimate that in a match between two sides of equal ability, the team winning the toss and batting first has a 57% chance of winning the match, a probability that rises to 69% if it also has home advantage.
By contrast, other research suggests that in day-only games, batting first is a disadvantage.
This suggests that batting in deteriorating light, even under floodlights, is a serious handicap.
And it means day-night games are unsatisfactory as their outcome is (partly) known before a ball is bowled.
One solution to this might be to have split innings, with teams batting for 25 overs alternately.
