What would your advice be to a left arm wrist spinner who is not very accurate and almost always pitches it up way off of off stump? And whenever he pitches it in line it spins away in the leg side to become a massive wide?
And he is quite slow.
1. I can't bowl the googly. It becomes top spinner everytime.
2.. And when I pitch it in line, it spins away to become a massive wide.
3. There are usually very few LHB's in the opponent team.
From the other thread - "I usually pitch it on the 5th stump, looking to spin it sharply into the stumps" - well, that's pretty much what I do. I assume this is from over the wicket - if it turns back in, then great, if it doesn't it goes across the r/h batsman with the angle.
I get a quite a few wickets from filthy offside deliveries, as long as the length is right; full tosses and long hops are getting blasted whatever the line, although the former is probably preferable - a sharply dipping full toss is more likely to induce a mishit than a short ball. If you bowl a lot of variations, the line can come back towards off stump a bit, but not much further towards leg than that - as you say, anything turning down past leg is a wide at best, although I'm often surprised at how many batsmen are incapable of letting it past and fell compelled to try to launch it anyway.
As far as your general accuracy goes, like they say up thread, it's really hard to say much without seeing your action. If you haven't videoed yourself bowling, then do so - your body is probably not doing what you think it is, and you need to capture some of the deliveries that go down leg and see if there is a common thread. I used to slide down leg a lot (especially when tired) and noticed that my right side was collapsing a bit, and I wasn't bracing my front arm properly as the bowling arm came over - maybe you're doing something similar, maybe not. It would of course be much better to see a coach if you can.
You said on the "
How do left-arm wristspinners have the actual effrontery to even exist" thread that you can't bowl a googly and that it comes out as a topspinner. This isn't ideal - you will be a far greater attacking threat with a ball that turns away from the right hander. I can't think of a a left-arm wristspinner at professional level that doesn't have a wrong'un, and a lot of them almost bowl it as a stock delivery. A top-spinner can be an intermediary step to a wrongun, and you might just have to get your wrist rotated round a bit further - can you bowl one underarm/roundarm? Standard advice is to start underarm & get used to the feeling, then progress to roundarm over about 15 yards, and then progress to 22 yards. Having said all that, I haven't got further than roundarm, attempting over the full distance either produces an offbreak or a full-toss into the offside netting. I'm still working on it but right now my main variation is an orthodox fingerspin delivery, which is working well. I'm careful to make the action as similar to the stock ball as I can, but I'm surprised how few batsmen pick it - it seems pretty obvious to me, but then I don't play at a very high level, and I imagine that better batsmen would spot it straight away, so I'm still working at a googly, but it's made me much harder to line up and slog.
As far as LHBs go, the lower you go, the rarer they are generally - I hardly ever face one. If you can develop a variation going away from the r/hander, this will help a lot, but bear in mind that you face right hand bats all the time, whereas they probably don't see left arm wristpin all that often.
