Have the new rules made ODIs an unequal contest?

The India-Australia ODI series was a relentless run-fest, but the overall run rates haven't changed much since the new rules came along

The first two days of the Kolkata Test has been a pretty good contest between bat and ball, but the three weeks preceding that was - at least in India - largely about batsmen smashing bowlers to all parts of the ground, and over it. The ODI series between India and Australia was a non-stop spectacle for the fans who wanted to see a deluge of fours and sixes, but for others who wanted a more even tussle it was a bit of a bore. There were nine instances, in 11 innings, of teams scoring more than 300, of which five totals exceeded 350. Both are records in a bilateral series. There was a barrage of fours and sixes, no total was safe, and Vinay Kumar became the first bowler to concede 100-plus runs and yet finish on the winning side in an ODI match. (For more details on all the records from that series, click here.)

The flat nature of the pitches and the quick outfields exacerbated the plight of the hapless bowlers and brought the focus on the new rules which were introduced into ODI cricket on October 30, 2012, especially the stipulation that only four fielders would be allowed outside the circle in the non-Powerplay overs. The earlier limit had been five, and this 20% reduction was one of the main reasons attributed for the unusually high scores. While this batting fest was on, there was another series going on which wasn't impacted similarly by the rule change: in the first ODI between Pakistan and South Africa in Sharjah, South Africa scored 183 and then restricted Pakistan to 182 to snatch the low-scoring thriller by a run. In the second match, Pakistan scored only 209 and yet won by 66 runs.

Obviously, this new rule hampers the fielding side in perfect batting conditions - Bangladesh chased down a target of 308 against New Zealand last week - but has it completely changed the balance of power in ODIs? Have run rates significantly increased worldwide in ODIs over the last year, or is it restricted to a few regions, where the new rule seems to have benefited batsmen unfairly? Here's what the numbers say.

What stands out in the table below, which looks at ODI averages and run rates since October 30, 2012 and the previous four years, is how closely the numbers are stacked up each year during this period. In the last year since the rule change the rate is 5.05; in the two years before that they were 5.03 and 5.07. Between October 30, 2012, and October 12, 2013 (before the start of the India-Australia ODI series), it was 4.98 in 114 matches. Clearly, it appears that overall the rule change hasn't impacted run rates at all in the last year.

Year-wise ODI stats since October 2008
Period ODIs Average Run rate
October 30, 2012 onwards 126 30.33 5.05
Oct 30, 2011-Oct 29, 2012 93 30.65 5.03
Oct 30, 2010-Oct 29, 2011 149 30.43 5.07
Oct 30, 2009-Oct 29, 2010 146 30.31 5.02
Oct 30, 2008-Oct 29, 2009 148 30.42 5.08

The scoring rates in each country over the last three years also hasn't changed drastically. Since October 30, 2012, it's 5.59 in India, which is marginally more than the rates between October 2011-2012, and October 2010-2011. In other countries the results are mixed: the rates have diminished in Australia and in the UAE (though the UAE sample size in 2010-11 was only four matches). The rate in South Africa is less than the previous, but more than it was in 2010-11. Admittedly, some of this also depends on the strength of the teams which tour those countries in a given year, but the overall spread tends to suggest that there hasn't been a significant change in scoring rates in most countries since the introduction of the new rules. (Click here for Kartikeya Date's piece in the Cordon, which shows that scoring rates go up in matches involving India.)

ODI run rates in each country over the last few years
Host country Last year-ave RR 2011-12-ave RR 2010-11-ave RR
India 37.65 5.59 33.97 5.43 31.83 5.29
England 29.04 5.23 34.25 4.91 34.47 5.64
Sri Lanka 31.82 5.22 33.61 5.19 28.78 4.82
South Africa 30.42 5.19 37.17 5.51 26.08 4.98
New Zealand 32.43 5.16 31.22 5.28 30.88 5.36
Bangladesh 26.97 4.97 30.96 5.00 28.67 4.71
Australia 27.47 4.94 32.20 5.30 30.15 5.28
Zimbabwe 32.47 4.89 - - 35.78 4.96
West Indies 29.65 4.81 26.05 4.90 30.76 4.69
UAE 25.98 4.37 28.83 4.76 33.15 5.46

There is also a fear that a combination of two new balls per innings and fewer fielders outside the circle will destroy the effectiveness of spinners in ODIs. The table below, though, again shows little to differentiate between the bowling averages and economy rates for spinners and fast bowlers in the last three years. Since the latest rule change, spinners have averaged 4.69 runs per over, which isn't very different to the economy rates in the previous two years. In matches played in India, the rate has increased from 4.74 in the previous year, and 4.86 in 2010-11, to 5.05 this year, but then that's also because the overall run rates in India have gone up owing to the run-glut in the India-Australia series.

Year-wise stats for pace and spin in the last 3 years in ODIs
Period Pace-ave Econ rate Spin-Ave Econ rate
October 30, 2012 onwards 30.84 5.06 33.23 4.69
Oct 30, 2011-Oct 29, 2012 32.48 5.15 33.88 4.55
Oct 30, 2010-Oct 29, 2011 31.60 5.16 33.73 4.68

In the India-Australia series, one of the trends that was noticeable was the relatively slow scoring rates during the mandatory Powerplay overs: it was only 5.33, compared with 7.85 in the batting Powerplays and 6.86 through the rest of the innings. The lack of fielders in the outfield through the non-Powerplay overs meant that the early restrictions weren't as vital to the batting teams.

In all ODIs played since October 30, 2012, the run rate in the mandatory Powerplay overs has dropped to 4.25, from 4.75 in 2010-11 and 4.52 in 2011-12. Correspondingly, the rates have gone up a bit in the last ten, to 7.27 in the last year from 6.69 in the previous year.

Overall, though, there's little change in the scoring rates since the four-fielders-outside-the-circle rule came into effect. There were bizarre numbers in the India-Australia series, but the bowlers will hope that was a one-off. Or perhaps it's taken the batsmen so long to wisen up to the opportunities that have opened up with the rule changes.

Run rates in different parts of an innings in the last 3 years
  0-10 10.1-50 40.1-50
Oct 30, 2012 onwards 4.25 5.29 7.27
Oct 30, 2011-Oct 29, 2012 4.52 5.17 6.69
Oct 30, 2010-Oct 29, 2011 4.75 5.18 7.02

ALTAFPATEL-The pitches at UAE cant be classified as true they are just mine fields , rank turners to suit home team with 3 spinners ,see the deference the so called world class spinner who could not win any thing in UK, (CHAMP.TROPHY) IN WI, -even in ZIM, again on wlcket taking spreein u r DEN on these rank turners ,pl dont make tall claims the moment u see 200+ u r players starts shivering - in the on going SA-PAK -series only 1 match was below 200 , other one-209 & rest are 250+ , u cant say that 260+ are low scores , which u r self asumed world class bowling conceded, credit goes to SA really great batting , i cant understand when u people demean our bowling saying as weakest , where as this so called weakest bowling won us matches in UK, WI, SL, & ZIM, what is u r score line in those places in the recent past.

Where's the status of reverse swing now in ODIs?

Posted by Paulo on (November 8, 2013, 19:35 GMT)

As I've said before, 2 new balls can help bowlers in some countries because it stays swinging for longer. Hence Nick Knight before the champions trophy said that his only problem with the 2 new balls rule was that "the pinch hitter has gone out of the game". The 2 new balls favours bowling in some countries and batting in others.

@ siddhartha87 have you measued the ground? every ground in the last concluded Aus series had 75 metres boundary in front of the pitch

Interesting - 3 days ago, I had written about this in a similar manner.

i don't think that the new ODI rules has made the contest uneven between bat and bowl.The problem is with the flat tracks prepared by Indian curators. I think the pitch should have at least some venom for fast or spin bowlers. look at the series between SA vs Pak and one can get the point that it's not the problem with ODI rules but it's the extreme flat tracks causing us to question new ODI rules.

Can't believe Bangladesh actually chased down 300+ and thrashed the Kiwis yet again. Anyway have to admit India no doubt have the flattest of pitches in World Cricket but I don't understand the fuss because it didn't break any regulations of ICC and such pitches weren't used for test matches at least otherwise for that form it would've been a serious problem.

@ahmadmobeenqazi don't know why Kohli not mentioned when pointed out Dhavan, Rohit !

The high scores in the prev Aus-India ODI Series were primarily due to the weak bowling of India being exposed by Aus & the strong batting of India eclipsing the relatively stronger bowling of Aus. Of course all these things happened on flat tracks and so we had scores that were about 30-40 more than what anybody had imagined.

Look at the flip side...

The current SA-PAk series has seen really low scores & pathetic scoring rates. They make for very poor viewing. Keep in mind that both SA & Pak have been struggling even after these new rules came into force.

At least for Pak there is the reason that they get to play very little cricket & have little chance of exposing their young players to top players so that they could get better. Internal politics in the team & the flux their board is always in also do not help them.

But what about SA? They are among the leading nations in the world & have a high quality domestic structure. Yet they are can score only 180s & 140s?
