Fielding is a crucial part of cricket and there are many areas where a fielder will be placed.
The position names can seem a little strange to the untrained eye.
You can field in the slips, at gully, at square leg or even at silly point.
When a position is described as 'deep' or 'long' as in deep mid-wicket or long off then the fielder is usually placed right out on the boundary.
Similarly a position prefixed as 'short' or 'silly', for example silly point means a fielder is placed in closer than a conventional point fielder would normally stand.
