For me, playing club level spinners, it is as much about playing the bowler as playing the ball. I open the batting, so I guess I probably face 10 spinners a season. Most of them come on when I am well set, so most of the time I have some advantage I would say. Bearing in mind I'm an OK bat, I think it is fair to say that of any 10 spinners I face, I only rate 2 or 3 as actually much good. So the first issue is to sort the wheat from the chaff as it were.
Good spinners at my level tend to be the ones who bowl straight, reasonably quick and (on the whole) full length. These are both off spinners and leggers, and it is easy to recognise their ability within 3 or 4 deliveries. They are confident enough to pitch up consistently and know that it is their best chance of success. With a well stocked Cover and Mid-Off field, they should be safe enough, and they want me to drive anyway. In this situation I will always look to get on the front foot, and play with a straight bat. Better to be on the front foot and need to rock back, than be caught back in your crease to a quick, full pitch delivery I think. I take Middle-and-Off guard, so I try to be careful to avoid playing around my pad, and from bad experience in the past I now tend to avoid sweeping. Let's be honest, against a good spinner you have to be careful, so I generally just look to drop the ball down for a single somewhere and let the other fella have a go. Bad balls will come if the bowler gets impatient, so you just have to wait.
The better news (for batters) is that most club spinners are rubbish. I face them when the oppo skipper has run out of ideas or when his first 3-4 bowlers are knackered or bowled out. You have to take maximum advantage of a bad spinner, but they are usually so slow that you have to be prepared to give it a proper whack to get maximum shot value. I try very hard to play from the crease, and keep it on the floor - at least for the first couple of overs. Once I have the confidence I do go down the track, or often just fake it, watch him pull it down short, rock back and belt it over Midwicket. At this stage the key is to try and milk the spinner as carefully as you can, enough to build a score, but not so much he gets pulled off. If you can keep him on for another couple of overs, that's 20 runs to the team.
Best of luck with it!
