Didnt really matter if she caught it, but yes its still INT and therfore an out.
Dont make this difficult for yourself. Its treated like any other fly ball for the BRs and the batter is out whether caught or not.
Be sure to let this play finish, cause players and coaches dont get it and scream all sorts of wierd stuff that can make it a complicated play. Dont call time til your sure its over so the correct calls can be made.
