IFF mechanics

[Little Jimmy]

This happened yesterday. 13-18 rec game using ASA rules. I'm solo. Bases loaded. 1 out. Wind is howling and whipping through the field. Batter hits a pop up toward pitcher which would normally be an easy out. With ball at its apex I call IFF (coach later says he didn't hear, more on that later) and just then a huge gust of wind blows and the balls starts driting toward the 1st base line. I immediately add "if fair" and wait. Ball hits ground 3 feet fair starts rolling toward line and at the last second pitcher picks up ball on the line (fair). I point and verbalize again "IFF, batter out". Pitcher throws to catcher who tags girl comming home (for some reason). 3rd out. Coach screems they didn't hear IFF("doesn't matter, I said it. Maybe the wind?"). Then he says "you didn't call that until the pitcher picked up the ball". "That was the 2nd time I called it coach" says I. More grumbling but life goes on.

Should I have verbalized the IFF the 2nd time when pitcher picked up the ball? I was trying to be clear on a close call but maybe the verbalization the 2nd time wasn't proper mechanics. Ideas?
