If he touched the ball in fair territory and then it bounced foul, it's a fair ball. LL Rule 2 Definitions - Fair and Foul Ball.

I guess the plate umpire wasnt sure if the ball was touched or not? If the ball is touched by the fielder, the location of the ball in reference to the foul line(not the actual marked lines as contrary to popular belief the lines dont mean a thing) is all that matters. If thne ball was judged not to be touched, lands on fair territory beyond 3rd the goes into fair territory we have a fair ball. If judged to not be touched and lands in foul territory its a foul ball.

A good PU, base umpire of theyre on the lines, will never say "fair ball". You do not have to get in a hurry to declare a foul ball because you cant take it back.

Incorrect. The foul lines are always in fair territory unless the ball bounces foul before passing 1st & 3rd.

You must have different rules. Travel ball?

Nope just regular usa little league

You must have different rules. Travel ball?

Rules on fair and foul the same in all codes im aware of unless you want to talk softball which are the same except in one situation

Thanks that's what I was thinking.
If bounced "in play" past 3rd and goes past foul line (bouncing or rolling) should be fair ball right? That's always been my understanding.
If touched and goes out regardless if past 3rd or not it's fair, right? That's always been my understanding from playing and watching for decades.
Why wait until the batter is approaching 2nd to call foul unless the home plate ump was cheating. Right?

Nope, all the same.

I don't know where you get your rules at so show me where they're written.

Thats the NFHS baseball rule. OBR could or could not be interpreted the same way

In that picture the PU might not be sure if the ball was touched by the fielder or not. That would be the reason for the delayed call. If it was clear that be ball landed in fair territory, and it wasnt touched then was ruled foul then the PU needs a talkin' to.
