A baseball term.
In baseball, you do not necessarily get a 'hit' just by hitting the ball. To have a hit, you must not only hit the ball, but hit it true (fouls don't count), and then run to first base (and perhaps beyond).
There are also things like fielding errors, fielder's choice, bunting, etc. that do not count as an at-bat, and therefore do not count as a hit, insofar as calculating batting average goes. These are enumerated in 7 ways to reach base without a hit, if you need more info.
Because I was confused, and Webster wasn't helping. I didn't want you to be confused like I was.
