Something a little different today: Fast bowling line and length. The wealth of information on ESPNCricinfo's site makes for some fascinating observations on where to bowl a cricket ball. This information is taken from ESPN's cricinfo coverage of the Champions' Trophy One Day International between England and Australia on 8 June 2013.
In a nutshell, for a right armer, it should pitch OUTSIDE OFF STUMP. Exhibit one: all right arm seam bowlers bowling for England against Australia:
Given right armers will be bowling "over the wicket" (that is, to the left hand side of the stumps at the bowler's end) There is a clear "line of best fit" here which shows the line is towards middle stump.
When bowling to left hand batsmet they will tend to aim across the batsman and well outside his off stump. There's a very good reason for this: they'll get tonked if they put it on his leg side!) Because of the right armer's natural action, the ball will tend to "swing" in the air from right to left: away from the right hander and towards the left hander.
Note also that, to a right hand batsman, ALMOST NOTHING PITCHES IN LINE WITH THE STUMPS. The ball *should* land outside the line of off stump. Note also that NOTHING, BUT NOTHING, goes down the leg side.
Also interesting to see what a difference consistency makes:
Here's Mitchell Starc, the Australian left arm opener. He is bowling mostly left arm over the wicket, but is bowling round the wicket occasionally, which will make his "scatter pattern" more varied, but not so much as to explain the wide spattering here - this is like a Jackson Pollock! Ten overs of this has cost Australia 75 runs for just one wicket - incredibly expensive in a one day game.
Compare that to Stuart Broad (After 8 overs: he's still bowling as I write!)
This is really remarkably consistent line and length. But for one yorker, everything is short of a length - just a bit to short to drive, but not so short the batsman is comfortable playing off his back foot. He has to be watchful, and as a result Broad is very economical.
I do agree - I work with the coaches at my native cricket ball, and also the laborious ball is often a challenge for the kids. we tend to use soft ball games to urge them wont to touching and catching.
ReplyDeleteWould you say Broads perfect length is around 6m from the stumps? Im trying to figure out the length to aim at my my stock fast ball
ReplyDeleteI would say the perfect ball is just short of a length. What you want is a batsman who's in two minds whether to go forward or back. Too short, and he can rock back and club it. Too full and he's on the front foot and you're fetching it from the long off boundary.
ReplyDeleteJust where that length is will depend on the track. The low, slow tracks of North London where I ply my trade you can dig it pretty short. On a bouncier track, not so much.
When choosing a cricket bat for a junior player it is vital that you select the correct size. An inappropriate choice - often the bat is too big - Cricket Bat arrest a youngster's development due to the weight of the bat being unwieldy and extremely difficult to control.
ReplyDeleteI would state the ideal ball is barely shy of a length. What you need is a batsman who's in two personalities whether to go ahead or back. Excessively short, and he can shake back and club it. Excessively full and he's on the front foot and you're getting it from the long off limit.
