Cricket World Ratings 23/8/2016



There’s been a lot of action in international cricket recently: every team with the exception of Bangladesh has been in action, and with the effect of a change in the rating order.  Since I started keeping track of test match cricket results using an Elo-style system, most of the matches played have ended in fairly predictable outcomes, but some of the recent matches have produced some surprises.  The first big shock came in Australia’s tour of Sri Lanka.  After a run of 11 undefeated games helped put Australia into first place both in my rankings and the official world ratings, Sri Lanka won all three tests in their recent contest.  This is all the more remarkable as Sri Lanka have a wretched record against Australia in general – in fact, prior to this series, they’d only won one test against them ever (and they’ve been playing test cricket since 1982).  In the first match, young batsmen Mendis (who was promising in the side’s recent tour of England) and veteran spinner Herath helped deliver a victory as the team recovered from an appalling start.  In the second game, Herath even took a hat-trick, while his colleague Perera collected most wickets overall.  The third test was more competitive but the eventual result less surprising.  Even at their peak, Australia have often looked weak in the Indian subcontinent, but these to lose three times in a row is poor for a side that had been beginning to assert itself at the head of cricket’s pecking order.  And indeed, Australia’s erstwhile dominance was not so strong that it could necessarily be presumed to withstand such results.

And for a while, it wasn’t clear which of three other teams might take Australia’s lead.  India could cement that position with a good win over the West Indies, but (because of the West Indies’ poor rating) needed a convincing set of results.  If England could see off Pakistan, the team would actually have beaten every other test side more recently than they’d lost to them, and would go top.  But a drawn series, or a series win for Pakistan, could have allowed Pakistan to take the top spot if India failed to win by a sufficiently convincing margin.  This whole blog is about my alternative system for ranking teams, and under this system, the calculations are slightly different; but it’s a fairly clear fact that no team is dominant in test match cricket right now, meaning that the top place would be subject to contest under any reasonable system.

And India’s hopes might have seemed to have been fading as their series against the West Indies unfurled.  They’d won the first test, and in the second, wickets from Ashwin (one of a number of contenders for the title of the world’s best bowler right now), and runs for Rahul and Rahane, saw India into a commanding position; but Roston Chase, who’d previously taken five wickets, scored a splendid undefeated century to secure a draw for the home side.  In the third test, the West Indies made a good start, and, although their position weakened, rain looked as if it may have saved them.  In the event, India sealed a win to take a 2-0 series lead, and to retain their own chances of taking the number one spot.  But rain wiped out the final test, restricting India's opportunities to gain in the ratings.

There were no shocks in New Zealand’s tour of Zimbabwe, where the visitors have won the first two tests by a crushing margin (thought this has little effect on the top of the rankings). New Zealand have since headed south to South Africa, where the first test was rained off.  Just one more test awaits in this series. 

England and Pakistan’s battle as arguably been more interesting: the third test saw the hosts recover from a poor start through a fine team effort, but in the fourth, the Pakistanis took control again and England count not return.  England’s eventual defeat saw the series drawn 2-2, and, as Pakistan won when the two teams last met, England’s hopes of a clean sweep of pairwise victories dashed.  England have many talented players (especially all-rounders) but a chronic shortage of frontline batsmen: in the series, five Pakistani specialist batsmen have made scores in excess of 70, whereas just Cook and Root have managed this among England’s supposed lead batsmen.  As spin bowling is another England weakness, and a tour to India awaits, it could be a while before England get another chance to go top.  As for Pakistan, their batting hero of the first test was 42 year-old Misbah ul-Haq, while in the final test, a double century was scored by 38 year-old Younis Khan.  It’s probably the last time we’ll see this pair on a cricket ground in England, but they depart on a high.

One issue which I have not extensively discussed yet on this blog is home advantage.   Has Australia lost to Sri Lanka at home that would have been an even more dramatic shock; Pakistan will be delighted to have drawn in England; India have a long series of home games coming up which represent a good opportunity to assert themselves in first position.  Players tend to develop the skills needed to flourish under the conditions they most often face; the advantage of playing at home is substantial. Though I haven’t done the maths, it’s possible that identifying which side is playing at home is as good an indicator of the eventual result of a game as any complex analysis of prior results. One certainly might seek to build this factor into a system, although neither my system nor the official one takes account of this at present.

So, after all this action, how do the teams rate?  Firstly, under my system, the current ratings are as follows:

India         110  -3      

Australia      93 -73         

Pakistan       93  +2        

England        89  -2         

South Africa   75  -1        

Sri Lanka      52 +73        

New Zealand    50  +7         

West Indies   -69 +15      

Bangladesh   -172      

Zimbabwe     -320  -5

While under the official system, India went top for 5 days, but after their final match against the West Indies was rained off, Pakistan nudged ahead of them:

Pakistan      111

India         110

Australia     108

England       108

New Zealand    99

Sri Lanka      95

South Africa   92

West Indies    67

Bangladesh     57

Zimbabwe        8

So there is actually a difference between the answers produced by the two systems, although both agree that there isn’t much to choose between the top sides.  The similarity of the absolute ratings, however, is wholly accidental, although it’s worth noting that India’s current rating of 110 (in my system) is one of the lowest ratings ever for a team in first place: the last time that the best rating was this low was in 1999, when South Africa and Australia were jousting for the number 1 spot (and when Bangladesh were not yet a test team, which is important, as the ratings are adjusted so that the mean strength is zero).  One way of looking at this is that we’re currently lacking any great test sides.  But another view is that the top rung of international cricket has rarely been this competitive, with very little to choose between the top four teams in particular. Still India, with their forthcoming home series, have to be the favourites to be on top in a few months time.
