105 overs a day (helps work, rest and play?)

overs per attack per day-page-001Colin Graves becomes ECB Chair in May 2015. Prior to taking office, and being burdened with its responsibilities, Graves has used media interest in his appointment to state that old orthodoxies and recently reinforced decisions won’t necessarily hold sway under his leadership. KP, county T20 and Test match duration have all had their existing status opened up by Graves.

The new Chair has made the case for 4-day Test matches, with 105 overs played each day. Out would go the financially loss-making fifth day.

There has been some well-informed scepticism, responding to the suggestion that 105 overs could be bowled in a day. The current minimum – 90 overs – is usually only reached with play extending beyond the core six hours. How long would it take our glove-changing, drinks-sipping, field-tinkering cricketers to complete an additional 15 overs? And would the audience want to be there until the end?

I have parked that concern for this piece. Instead, I have tried to model the impact of 4-day Tests in the UK, with the following issues in mind:

  • would shorter Tests impact on results?
  • would longer days increase the burden on bowling attacks?
  • would 4-day Tests provide international players with more time for recuperation, or county appearances?

To explore these questions, I have applied Graves’ proposal to the last 14 England home Test matches – i.e. the summers of 2013 and 2014. I have assumed that each match, under these new conditions, would have played out in exactly the same way that it did in reality. I have simply distributed the overs actually played across the four days available – at 105 overs per day (less two overs per change of innings). Graves wants games to continue under lights and so where a day was halted for bad light, I have let the match continue. Graves has no proposal to combat rain, so those stoppages hold.

An example of how an actual game has been reconfigured according to the Graves conditions is shown below.

Overs per day comparison-page-001

All figures represent number of overs. The days are colour coded and the overs for each innings split up between the days occupied. The first coloured row is the actual distribution of overs per day. The second is the ‘Gravesian’ adjustment.

The example is from the 1st Ashes Test of 2013 at Trent Bridge. Under the adjusted method, Australia’s first innings is 23 overs further advanced at the end of day one. By the end of day two England’s second innings is 40 overs further advanced than it was in reality. In 2013, day three was entirely taken up with the rest of England’s second innings. In the alternative reality, Australia are 37 overs into their second innings. Day four saw Australia 71 overs into their fourth innings chase, but under the accelerated version the game ends around tea-time of what would be the final day. The real final day saw 39 overs of cricket before England’s dramatic victory.

The 4-day 105 over variant (theoretically) delivers 30 fewer overs per match than the current 5-day match. Of the 14 Tests examined, only one would have reached a different outcome with overs reduced by the Graves method: England v Sri Lanka at Headingley. In that match, the final wicket of Anderson fell in the final over of the fifth day. Using the Graves rules, that game would have been shorn of 18 (not 30) overs (owing to days 1-4 averaging 87 overs). In the real match, England were 229-9 18 overs from the close.

There is a risk that the fourth day would become the new fifth day – i.e. advance ticket purchase a risk. Three of the fourteen Tests would not have lasted until the fourth day (another only would have done so due to a wash-out earlier in the game). Two more matches would have had less than half a day’s play on the fourth day.

What would be the impact of 105 over days on the bowling attacks? The chart below shows the proportion of days that a bowling attack would bowl at least a given number of overs under the two regimes.

overs per attack per day-page-001

Currently, on one-fifth of days, a bowling attack delivers zero overs; because its side bats all day, the day is cut short due to weather, or because the match comes to an end. In 4-day tests, that would fall to one-in-seven.

At the top end, a very similar proportion of days (18-20%) would involve attacks shouldering 80+ overs. However, one-in-ten days would see an attack bowling 100 overs or more in 4-day tests, which didn’t happen at all in the real sample (but could do on occasions when time is made up for stoppages earlier in the match). Based on this sample, across a closely matched five Test series, each side could expect to spend two days in the field bowling over 100 overs.

Part of Graves’ support for 4-day Test cricket is the time it frees up for players away from international duty. He also stated that all Tests should run from Thursday to Sunday. I have compared the scheduling of the last Ashes and India series – both of which were compressed into seven weeks – to a series of five 4-day Tests.

test schedule-page-001


At its most compressed (Graves 1), a five Test series could be wrapped up in five weeks. There would be three days downtime between the scheduled end and start of each game. A more likely option would see two pairs of ‘back-to-back’ Tests (Graves 2). Because of the constraint of starting all matches on a Thursday, this would extend the series to seven weeks, providing no reduction in elapsed time on the Australia series of 2013. The breaks between second and third Tests, and fourth and fifth Tests could allow international players to appear for their counties in one-day fixtures.

In summary, if it proved possible to motivate players to bowl up to 105 overs per day, holding Tests over four days would not effect the outcome of the majority of matches. With most matches taking fewer than 350 overs to reach a result, there is a risk that the fourth day would be unattractive to spectators.

Bowling attacks would occasionally have days in the field lasting 100 overs or more, but the daily burden of a bowling attack would not vary greatly from that experienced in 5-day Tests. I speculate that batting first would become more desirable because of the advantage gained if the first day is survived. The bowling attack would start day two with a ball 25 overs old, and so less likely to be able to strike back than with the ten over old ball of a 5-day Test.

Series of 4-day Tests that run from Thursday to Sunday, unless played over successive weeks, will not take less time to complete than 5-day Tests that start of different days of the week. If Graves is to reduce the demands of international cricket during the English summer, he will need to address the overall number of fixtures played.

    Congrats on the research, Chris. Have you tried sending it to Graves for his comments?

    I may be wrong, but I suspect he hasn’t thought quite so deeply about it.

    You were quite right to ‘park’ the concern over bowling 105 overs per day. It’ll rarely happen (or, if it does, play will end unacceptably late and under lights).

    Boycott’s oft-repeated view that the only way to speed up Test over-rates is to bring in run penalties is one I agree with. Going to a few days of Test cricket each year I’m always annoyed by the slow tempo of play, even by comparison with the LVCC games I watch (let alone Minor Counties or club cricket).

      Thanks Brian, I’ll try your suggestion.
      I assess a day’s play by the quantity and quality of incident, rather than number of balls delivered. Slow tempo when there’s nothing much happening is the really painful sort.
