The count reached one ball and one strike keep your chin up.
(This sentence is from baseball)
Here, what is the meaning of `cound' and `chin up'?
Could anyone explain it?
Usually, "keep your chin up" is an idiom that means be optimistic, stay strong, hope for the best. In this case, however, I think they mean it literally: keep your chin up so that you can watch the ball properly as it is pitched to you.
