It seems these days that there are a million and one variations with spin bowlers mixing it up in all sort of ways.
So, let us take a look at the glossary of deliveries for leg spinners:
A stock ball simply refers to the main delivery used by a bowler. It's not always what you think. For example, Anil Kumble's stock ball was, in fact, the top spinner.
For most leg spin bowlers your stock ball will be your leg break.
Breaks from leg to the offside, after drifting from off to the leg side. Seam is angled towards slip. The ball ideally will be hitting the top of off stump.
The main dismissal forms are caught (slips or keeper) bowled and LBW.
Although it looks like a leg break, the ball continues straight on after pitching, with a lot of dip in the air beforehand. Seam is angled towards the batsman.
The greater bounce brings catches from close fielders. It can be used as a stock ball or as a surprise variation.
The opposite of a leg break because the googly spins from off to the leg side. Your action appears to the batsman a leg break. Seam is angled towards leg slip and the ball come out of the back of the hand.
The key is deception off the pitch and so the googly should be used as a variation to bowl batters though the gate who are playing for spin the other way. Some spinners get stuck bowling the googly as a stock ball and if this happens you will probably need to do some repair work.
A little-know bit of history about this ball is that Bernard Bosanquet did not invent the googly. Other players have dabbled with this delivery years before he did. Although the ball will go down in history as the "Bosie".
Slider / back spinner / zooter
This ball is almost the opposite of the top spinner. The seam is angled towards extra cover and spins along its own axis. This delivery is refer to as a slider or back spinner and you will hear this name used in equal amounts. The zooter is what Shane Warne called his slider.
Whatever you call it, the variation skids on trapping the batsman LBW. It's great for strong back foot players who will get caught on the crease.
There is no one flipper. In fact, the flipper should really be the family of flippers. There are a variety of ways to bowl this delivery, but the main idea of a flipper is a variation that skids through quick and low after bouncing.
There are versions bowled by WG Grace, Grimmet, Benaud, Warne and a few more obscure historical cricketing characters.
It's tough to learn, but used as a skilful variation will get you wickets.
This ball is as it sounds: simply pushed through quicker that the stock delivery. The more you can disguise it the better because a common error is to make it obvious with a big change of run up and action.
I can think of no better example than the one delivered by Shaid Afridi, which has brought him tons of wickets. The variation in pace is huge but it's hard to pick.
I realise that's a lot of deliveries and variations to think about, try and use. You can speed up the process of untangling the mess and come up with your own way of bowling successful spin with my Spin Bowling Tips guide.
