CricViz analyst Patrick Noone outlines how England should target Bangladesh’s key players.
Australia pulled off an impressive victory within three days against India in Pune, their first win in India since 2004. This comes off the back of a middling home season where they lost 2-1 to South Africa but recovered to beat Pakistan 3-0. CricViz looks ahead to what England might expect later this year in the 2017-18 Ashes
Australia lost the first two Tests of the season to South Africa with their worst performance occurring in Hobart, losing by an innings-and-80 runs. They then won the day-night contest in Adelaide before sweeping aside Pakistan. The chart below shows the scores and the number of wickets they lost in each of their 11 innings.
The blue bars (indicating victories) show that they generally racked up big scores in the first innings and either scored quick runs before declaring or chased down small targets in the second innings.
Driving these performances were Australia’s top order, three of whom scored at least 500 runs over the six matches. The table below shows their top ten run-scorers.
Newcomers Peter Handscomb and Matt Renshaw have adapted to Test cricket quickly, scoring three hundreds and three fifties between them. This includes a Renshaw 184 against Pakistan in Sydney.
Australia’s attack was spearheaded by their opening bowling duo of Hazelwood and Starc, picking up 60 wickets between them, and adequately supported by Nathan Lyon’s offspin (17 wickets). We will take a closer look at what made them so successful later in the piece.
The dependable Steve Smith
Firstly, let’s take a look at Australia’s captain and top run-scorer this season, Steve Smith, who scored two hundreds and three fifties from 11 innings. The beehive plot below shows where he scored his 653 runs.
From first glance there isn’t much we can say. Perhaps he puts away a lot of full or wide balls to the boundary and picks up singles from balls closer to the stumps. We can filter this further to see how he performed against particular bowlers and types of bowlers.
Smith faced a lot of Yasir Shah so it’s not surprising that he scored the most runs and was dismissed by him most often.
The heat map above shows the distribution of deliveries faced by Smith from Yasir with his dismissals in red. He favoured a good length just outside off-stump, shown by the dark green regions. Smith pounced on anything marginally short or full.
The blue balls show Smith’s boundaries many of which are just above the dark green areas. The pitch map below also illustrates how Smith punished Yasir for bowling too short or too full.
David the Destructive
Warner also enjoyed a prolific season scoring nearly 600 runs at a remarkable strike-rate of 93.
Warner targeted the spinners more than the seamers, scoring at a strike rate of 113. The heat map below shows how he scored his boundaries against spinners. Deliveries wide of off-stump and fractionally short were, more often than not, cut to the boundary.
In contrast, the heat map below shows the distribution of dot balls for Warner. Spinners who bowled closer to middle and leg stump with a more consistent length generally kept Warner quiet.
Against seamers it’s a similar story with Warner dispatching deliveries wide of off stump of any length, shown in the heat map below.
A seam bowler’s best bet to restricting Warner to dot balls is to bowl back of a length on off-stump as the heat map below shows. There isn’t really an obvious pattern in his wickets (shown in red) which suggests his dismissals come about from a lack of concentration or simply one hit too many.
Starc and Hazlewood
Australia’s opening pair put in a big shift for their side, between them bowling more than half the total overs in their six home Tests. The heat maps below show how they bowled to both right and left-handers with their wickets in red.
They both bowled quite consistently slightly back-of-a-length just outside off-stump. They did however get many of their wickets from fuller and straighter deliveries indicating that they used movement in the air and off the pitch pretty effectively.
The histogram below illustrates how much Starc and Hazlewood swung the ball. Negative values of swing, measured in degrees, indicate that the ball swung away from the right-hander and swung in to the left-hander and vice versa. Starc mostly favoured outswing (to right-hand batsman), while Hazlewood employed inswing the majority of the time. However, the distributions overlapped suggesting both bowlers had a number of deliveries that swung in both directions. It’s notable how similar the distributions are in terms of height and width – both bowlers had similar plans in terms of how often they bowl their stock delivery compared to their variations.
We can take a look at how much Starc and Hazlewood swung the new ball and when it got older.
The graph above shows the absolute value of the swing (how much it swung regardless of direction) during a particular over. A moving average of six overs is taken to dampen out the fluctuations. Both bowlers swung the new ball, the magnitude of which steadily declined until the 10th over. Hazelwood is generally a bigger swinger of the ball up until the 30th over, when Starc starts to visibly make use of reverse-swing between the 30th and 50th over. Hazlewood swings the ball most prodigiously with a 70 to 80 overs old ball, although it should be noted that he only bowled two overs in this period. When the second new ball is taken after 80 overs, a similar trend is seen as with the first new ball.
Additionally, Starc and Hazlewood extract pretty much the same assistance from movement off the pitch. The histogram below illustrates this where, as before, negative values indicate movement away from the right-hander etc. The opening pair marginally favour seam movement away from the right-hander but are more than capable of bringing it back in or away from left-handed batsmen.
We can take a quick look at a similar plot that shows how much spin Nathan Lyon gets.
Lyon has quite a broad distribution indicating that he varies the amount of revolutions he imparts on the ball, as well as being a consequence of the different pitches he bowled on. There is a slight bump at 0 degrees – his quicker and flatter delivery which he bowls about 5% of the time.
The beehive plot below shows Lyon’s release points when bowling. Over the wicket, he is fairly consistent bowling quite wide of the crease. When going around the wicket, he varies his release point a bit more, bowling from quite close to the wicket to very wide of the crease.
Finally, we can also take a look at which grounds are most conducive to swing and spin bowling.
The table above shows the average swing, seam and spin in degrees at each of the grounds that hosted a Test this season. England will be playing in all these grounds apart from Hobart. The most swing-friendly ground was Perth although it was also the least seam-friendly and spin-friendly ground. Brisbane offered the most spin of all the grounds.
The graph above shows distributions for Perth and Adelaide, the grounds with the highest and lowest average swing. It is evident the Perth has a shorter and wider distribution indicating a large range of inswingers and outswingers. Adelaide has a narrow range centred around 0 degrees, although there is a slight bump towards fairly big outswingers. This data coupled with knowledge about how much a ball swings when it is a certain number of overs old can be exploited by England when choosing how many seamers to play and when to bowl them.

Wide turn stymies spinners
This was a difficult pitch to read with ball-tracking data indicating that it took significant turn from the second day onwards and by the third day was taking more turn on average, 5.14 degrees, than the pitch in Dhaka did at the same stage, 5.09 degrees. The graph below shows the rate at which the pitch turned as the match progressed. However despite this significant deviation only 21 wickets fell in the first 380.1 overs of the match and only when eight fell in the last 69.2 overs did the scorecard begin to reflect the amount of turn on offer.
The critical difference between this pitch and the one in Dhaka was that the extra grass on this pitch held it together far better and for longer meaning in Rajkot the sharpest turning deliveries predictably pitched in worn areas of the pitch, whereas in Dhaka balls spun big unpredictably from previously compact areas of the pitch that were broken up by the impact of the ball.
The nature of this pitch meant that the sharpest turning deliveries pitched well outside the line of the stumps, nearer the bowler’s foot holes, as illustrated by the pitch map above. Naturally more of a threat is posed if balls turn big from within the line of the stumps. 41% of the 58 deliveries that turned more than eight degrees but did pitch within the line of the stumps were bowled in the fourth innings when the pitch was most worn.
England’s spinners improve; India’s get worse
Speaking after the match England’s coach Trevor Bayliss suggested that their spinners had improved their control of length. Ball-tracking data shows this not to be the case with England’s length percentages remaining almost exactly the same as in the Bangladesh series. What they did improve however was their line, illustrated by the pitch map below: they maintained tighter groupings and conceded runs at 3.36 runs per over compared to 3.63 against Bangladesh as a result.
India’s spinners meanwhile bowled with less control than against New Zealand, as illustrated by the pitch map below. This was the flattest of the four pitches India have played on this season and England’s first innings was the longest they have been in the field in a home Test since they played England in Kolkata in 2012. In these less helpful conditions Ravichandran Ashwin and Ravindra Jadeja struggled to maintain the exceptional groupings they managed against New Zealand.
England’s best spinner in this match was Adil Rashid who took match figures of 7 for 178. Rashid displayed significant improvement in his control of line and length from the Bangladesh series, illustrated by the pitch map below.
In this Test Rashid landed 60% of his deliveries in a two metre range between four and five metres from the batman’s stumps, in the Bangladesh series that figure was just 46%. The principal improvement came in bowling fuller: against Bangladesh he dropped 14% of deliveries shorter than six metres from the batsman’s stumps, in Rajkot that figure fell to just 9%.
England commit forward and back
It is perhaps too soon to pass judgement on England’s batsmen against spin given that this pitch did not break up and turn as both pitches in Bangladesh did and as they are expected to do more in the rest of this series. However, England’s four centurions, Joe Root, Moeen Ali and Ben Stokes and Alastair Cook, as well as debutant Haseeb Hameed showed really encouraging signs with their footwork against spin. None of Root, Moeen or Stokes played a single shot with footwork categorised as “no movement” in their hundreds suggesting that they committed clearly to going forward or back, which is critical to playing spin well, while Cook played just 28 out of 290 balls in the match as such and Hameed just 12 out of 259.
England escaped defeat in Chittagong thanks largely to a superb all-round performance from Ben Stokes and Bangladesh’s first innings batting collapse; they were not so lucky in Dhaka where their shortcomings playing and bowling spin were exposed again and they crashed to a heavy defeat. There is no shame in losing to this Bangladesh team but there is shame at the manner of the result, in which their batting, bowling and fielding were alarmingly substandard.
It is difficult to ascertain which area of their spin-game, playing it or bowling it is a greater problem and quite frankly it is facile to apportion blame to one or the other; both were poor and both must be improved dramatically if they are to avoid a thrashing at the hands of India.
As bad as England’s batting was though, chasing 273 in the fourth innings was always going to be a very difficult task on a turning pitch against an excellent spin attack, and the size of that run-chase can be traced back to bowling and fielding errors throughout the Test.
After the match Alastair Cook was forthright in admitting that “we didn’t bowl great. And yes, their spinners did out-bowl our spinners. We’re not hiding behind the fact that we haven’t got world-class spinners.”
If the spinners England do have cannot exploit helpful conditions at their disposal then they are always going to struggle to win matches on the subcontinent because they will more often than not be chasing too many runs.
In the first Test England’s spin problem was primarily their inaccuracy and in the second Test the same can be largely said again. England’s inability to land the ball in roughly the same area consistently contributed to Bangladesh’s spinners bowling 15 maidens in the match compared to England’s eight and 50 in the series to England’s 21.
This failure to build pressure prevents spinners finding a rhythm against batsman and lining them up. Balls that turn fractionally more or less than preceding deliveries are far more dangerous if they are bowled at the same batsman rather than a different batsman because the same batsman is more likely to be influenced by the ball before and play down the wrong line.
Cook said that he would be interested to see the stats comparing England’s spin lengths to Bangladesh’s, suggesting that their bowlers maintained a better length. In fact both sets of spinners bowled very similar lengths overall [see below] with Bangladesh over-pitching slightly less, but both teams landing about 60% of deliveries in a two metre range between 3 and 5 metres – categorised as a ‘good’ length for spin bowlers.
England’s lengths, were almost identical to the first Test [see below] while Bangladesh’s actually got slightly worse. The home team were able to maintain more control because they bowled far tighter lines [see above]. Bangladesh’s pitching line groupings are tighter and straighter than England’s which forces the batsman to play and increases the chances of getting a wicket bowled or lbw.
Moeen was the most accurate of England’s three spinners [see below] and improved the percentage of deliveries bowled in the 3-5 metre range from Chittagong from 58% to 61% by cutting down on over-pitched and short deliveries. He also improved his line considerably – recording a far higher percentage of deliveries that would have gone onto hit the stumps. Rashid’s lengths actually got worse from Chittagong, most notably pitching 13% of his deliveries six metres or shorter. Ansari, meanwhile, recorded better lengths than Gareth Batty did but struggled to maintain his line.
Speaking after the match Cook explained the problem inaccurate bowling poses for setting fields. “You always feel you are a fielder short,” he said. “If you are leaking four, five runs an over in a low scoring game you have to put your boundary-riders out. It would be great if you could attack but you have got to hold your line and length better.”
England struggled to play spin just as much as they struggled to bowl it. Their dramatic collapse from 100 for 0 to 164 all out in a single session was the vertex of a problem that had been made all too apparent in the three preceding innings in the series in which they were 106 for 5, 62 for 5 and 114 for 6.
As has already been mentioned, batting in these conditions is not easy and Bangladesh have a very good spin attack, however to lose ten wickets in a single session is indicative of a more deep-rooted problem.
In terms of personnel, five of England’s top seven: Cook, Joe Root, Moeen Ali, Ben Stokes and Jonny Bairstow, are proven performers at this level and are guaranteed selection, while Ben Duckett’s second innings fifty showed enormous promise. Only Gary Ballance, who could well be dropped for the first Test in India, can be said to be out of his depth. In this sense England’s problem is not who, it is how – it is technique and strategy.
What has characterised the success of Bangladesh’s spinners, like that of Ravi Ashwin, Ravi Jadeja and Rangana Herath too in recent years, has been the lack of ‘mystery’ in their bowling. Rather than doosras and carom balls posing the threat instead it has been orthodox spin bowling. Alongside their accuracy these bowlers’ chief weapon is very slight differences in deviation and the key variation is the one that goes straight on. What makes this particular variation so deadly is that more often than not it is a natural variation, meaning it cannot be consistently read from the hand.
Eight of the fourteen dismissals of England’s top seven batsmen were to deliveries that deviated less than the average for any of the frontline spin bowlers [see below]. Playing against natural variations such as these is understandably difficult because there are no visual cues on which to predicate decision making other than the trajectory of spin after pitching, by which point the reaction time is negligible unless the batsman has gone back deep in his crease and therefore has some time to adjust, or, the spin can be nullified if the batsman is well forward and has smothered the turn. This reemphasises the importance of clearly committing either forward or back.
Given the average height and stride length of a batsman, deciding whether to commit well forward or well back is particularly difficult to balls pitched between 3 and 5 metres from the batsman’s stumps, within which 60% of all Bangladesh’s spinners deliveries landed, and also, as the match progresses and bounce becomes less predictable, balls pitched between 5 and 6 metres from the stumps, within which a further 21% of the spinners’ deliveries landed.
All the deliveries to dismiss England’s top seven batsmen excluding Ballance’s second innings leading edge pitched within this three metre range. This illustrates how difficult it must have been for England to commit either forward or back to those balls that they got out to because they were landing within a length range in which making the appropriate footwork is extremely difficult and even then once having committed either back or forward they then have to play the ball successfully. The less committed they are to going forward or back the less spin they will have smothered or the less time they will have to adjust.
The foundational aspect to succeeding against spin bowling therefore is reading the length well, something that England are going to have to work on ahead of the India series where the opposition is even stiffer.
