Foul ball, or not?
 

Ball is popped down third baseline. hits the ground foul, then bounces into a player the ump says is in fair ground? Whats the call?

One would need to know location relative to third base.
Infield side may be fair, outfield side may be foul.

infield side.

Infield side
 

If it lands foul between home and 3B and then rolls fair and settles there or is then touched over fair territory, it is a fair ball.
If it lands fair between home and 3B and then rolls foul and settles there or is then touched over foul territory, it is a foul ball.

If it is touched over foul territory by player still in fair or foul territory, it should be ruled a foul ball.
If it is touched over fair territory by player still in fair or foul territory, it should be ruled a fair ball.

I believe he is trying to say it is a fair ball.

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.

In this case it is fair no matter who it hits in fair territory. Defensive player, play on. Offensive player, it then becomes dead, AFTER it becomes fair. In fact if it was not fair, the offensive player would not be out.

What?!?!?!

I think what he's saying mccrowder is that technically speaking we first have to think fair or foul before killing it when a runner touches the ball.

He just said it in a roundabout way.

Exactly.

From pg 10-11 of Umpires Manual:

#6: On every ballted ball the progression of responsibilities is as follows:
a. fair or foul;
b. catch or no catch;
c. in play or out of play;
d. awarding bases

The order of our responsibilities has nothing to do with this post. The OP asked a VERY simple question which required only one clarification, and with that clarification, the answer is simply fair ball. Everything else you said was a red herring, and likely confused the OPer.

The instant it touches a player of either team, we have either a fair or foul ball. We may have other calls to make after that, depending on this, that, and the other thing... but one thing we surely have when it touches the player is an answer to OP's question. Speculating on what those other things may be only confuses this VERY simple issue.

Notice that the poster said that the ball hit a player in fair territory.

"Ball is popped down third baseline. hits the ground foul, then bounces into a player the ump says is in fair ground?"

He never tells us whether the BALL was in fair territory when it hit the player. Bottom line, we still don't have enough information to make the call. Where was the BALL?

Guys thanks for the replies. Let me start over. The ball hits foul half way down the third base line. Bounces and hits third baseman, who is in fair territory, on home plate side of 3b. Then it hits the ground in foul again.

Home plate side of third base? Maybe you need to start over again. Think it through its not that hard.

Fair ball. Fair/Foul in this example is determined by the location of the ball when it is first touched.
