[RPatrino]

You don't say what you do after the F6 fields the ball, apart from mentioning you "stay put with eyes on ball". If you made the call at 3rd from your original position at "C" then you didn't have the best angle you could have had. Once F6 fielded the ball and you could tell that the play would go to 3rd, move toward the 45 at third, even one step would have given you a little better look. After you get your look at the play while stopped, take a step or two more toward the 45 and make your call.

Bottom line, you made the correct call. The pause to look at your partner didn't help your situation in the eyes of the coach, especially if it makes it seem like you were listening to the bench to "help" you make the call.
