Foul ball, or not?

[Daryl H. Long]

Poster did not say whether the ball touched an offensive or defensive player.

The answers so far are correct. But only if we assume the player the ball hit was a defensive player.

If is hit an offensive player (baserunner) then still apply the fair/foul scenarios listed by SAump.

If ball deemed foul, then foul ball is declared whether touched by offense or defense.

If ball is fair and touched by offensive player then ball is dead, runner is out, and batter is awarded first base.
