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.
