Here's an example of some of the help an analyst can give to cricketers when they have access to the right information.
I’ve been provided with almost 16,000 deliveries from a club cricket team from the PitchVision software. I have decided to compare one bowler to one batsman, and see how they do against each other, and offer some advice based on my findings.
First, short balls. A total of four deliveries were banged in short and one run was scored. Here is the pitch map and view of the stumps.
PitchVision shows that the average bounce is 0.87 meaning the bounce is true to cut or pull. This batsman should look to attack more often than not when the bowler digs it in short
Next, good length balls. The bowler hit that good length 23 times and conceded two runs. Again the intent from the bowler would be to hit this length and keep it on around off-stump. If he is looking for some movement, then a touch fuller is a decent option but for that you need slip fielders in place.
Or if he is looking for an lbw or clean bowled, he should look to hit the stumps.
The above picture shows the balls that have been in the good length. Most of them are wide of off-stump. Only two deliveries are hitting the stumps, one being defended and the green one being tucked away for a single. Getting to the basics of batsmanship, rotation of strike is very critical in any form of the game.
There hasn’t been a lot of deviation to threaten Lucas from this length. Eight deliveries have deviated with two of them going down the leg side. One of the deliveries pitched 5.8m from the stumps and nipped back to finish on the fourth stump. Here is a closer look at all the balls that deviated from the good length
This hasn’t put this batsman in a spot of bother.
Now, fuller balls. A total of 25 deliveries have been in this region and 11 runs have been scored.
The balls that were put away for boundaries pitched on 4.8m and 4.2m from the stumps and both pitched on around 7th stump. A lot of room was provided to the batsman and he rightly cashed in on the opportunity to score runs. There hasn’t been deviation from the bowler. Only one delivery deviated around 0.9 degrees but it was the fullest ball pitching 3.2m from the stumps.
Interestingly, on the same line and fuller lengths, three more deliveries landed but they were not attacked. Here is the image to this.
A look at all the balls landing on the full length:
Again, the batsman should look to be a little more aggressive when it is pitched up. It is quite understandable that driving on the rise is a skill but out of the 24 balls, 18 have bounced around 0.52m which is a bit more manageable.
