Put your hand up

What does the expression "put your hand up" mean? This expression is also spoken by cricket commentators such as guys put their hand up and delivered a good performance. Could u please interpret that one for me?

As far as I am aware, 'put your hand up' means to confess. The reference is to school: a teacher would ask for an offender to admit to doing something, and the guilty pupil would 'put his hand up' to admit his guilt.

I am not familiar with the cricket commentator sense you describe.
