As a baseball catcher I’d like to ask about the relationship between the bowlers in cricket and the wicket keeper.
Baseball catchers offer signals to the pitcher so we know what pitches will be thrown. Do wicket keepers do the same as I can’t seem to pick up any.
How does the wicket keeper know what the bowler is going to bowl?

Great question Toby. Maybe signals are used in junior cricket but at a senior level, the keeper will know what the bowler is bowling without signals. They spend a huge amount of time together and also talk a great deal on the field. It's less about signals and more about planning strategies around specific batsmen. But the keeper should be able to read the bowler without signals.

Gidday Toby, keepers watch the bowlers hand and action to pick what delivery the bowler will bowl.However a cricket ball doesn’t always do what the bowler wants it to do. So good keepers will watch the hand and ball closely, knowing what the ball may do but reacting to what it does do. As unlikely as it is ,you should be thinking you will have to catch every ball. Hope this helps mate,
Ps you can have that job as a catcher all to yourself mate…..😂

About 40 years ago I was practicing at Sydney University. A baseball pitcher, who played for Uni was returning from injury and asked if he could pitch, and I “caught” the pitches using wicket keeping gloves. He stood about 25 metres away and threw the ball over an imaginary plate. I had kept wickets for much of my playing career and I had great difficulty catching pitches with gloves. The pitcher had late movement, rarely seen when the ball bounces in cricket. You should get your best fielder to ping a new ball from the bowlers end to be caught at the batsman’s end, around stump height.
