You can become a factor in the play if you don't read it correctly or pivot too early and in the wrong place. In the situation when the fly ball it taking F4 toward the line, you better not try to pivot in front of him. If the ball is hit extremely high then you have the time to locate the fielders and make your way into the infield.

You have to adjust based on the how the play unfolds. On a shallow fly, you won't have time to pivot, so you have to play it like a grounder and overthrow. Move toward the infield as far as the play will let you, without getting in the way. If the ball is dropped, adjust your movement into the infield based on player positioning. In most cases you won't be behind the BR.
