infield fly

[mccann]

Am I right to say that the base umpire never calls the infield fly but points to the location of the ball.

[Ed Maeder]

It is the primary call of the plate umpire but the base umpire can call it if they feel they need to. The signal is a closed fist not pointing to where the ball is.

[Alameda]

Raise right arm with fist closed. Verbally call, "Infield Fly."

That's our line up here anyway. And same with Ed, PU's primary call, but either ump can call it.

[wadeintothem]

talk about it in pregame to get that kind of stuff sorted out.
