Bump ball

A bump ball often leads to a 'crowd catch'! A bump ball is a delivery that the striker hits into the ground very close to the bottom of the bat. This has all the appearance of having come straight off the bat without touching the ground and, if 'caught' by a fielder, often looks just like a fair catch from the spectators' viewpoint. Indeed it can often look like a fair catch to the fielders, too. As nobody knows when this phenomenon is likely to occur, it's no wonder why umpires have to maintain intense concentration at all times when the ball is in play.
