I'm pretty proud of the field I've set tbh. I try to bowl mostly good length with the odd full ball, as a spinner, so I keep a sweeper at deep extra cover, deep forward midwicket, and a square fine leg. So any good shot off a poor delivery - either in the pads or wide outside off - has protecting to save the four. I have mid off and mid on in place too, so incase they time the full ball well, i have protection for the shot too. But often they don't, since it's unexpected.Its the fact that your confidence or the batsman confidence has nothing to do with the way dismissals are happening. The fact that their weakness shown by R3 has nothing to do with it. More over if you bowling to a field set for the batsman, that has nothing to do with it.
Lastly, if all these things are not working, isnt getting wickets just a random chance? How about the shots they get away with? The random slog at will, I could have the heaviest point, cover and third man regions, he will find a boundary if he wants.
And then I have a man at slip, who has caught a few off the reverse sweep in rookie mode but not done anything yet in Pro, silly mid off and short leg. The last two have taken many a blow on the body but have stopped the ball.
The only boundaries they have found off me are a lofted shot down the ground, and a pick up flick shot that found the gap between the two legside sweepers. Rest have been dots or ones, and I've beat the bat or hit the pads quite often. Giving them nothing to cut or pull either, just building pressure. Nothing has gone through third man either.
I got edges in rookie mode, but not yet on Pro, although it's still early days.
I don't bowl the same ball more than twice in a row. Maybe that's your problem?
