What if player tells you your call was wrong?

[Danny R]

A couple of folks here have said that I could not have legally changed my ruling even if I wanted to because the call is not legally appealable. I've changed my calls of balls to strikes a couple of times--was that illegal? The situation was that the pitcher threw a hard one right at my head. I ducked to avoid taking the ball in the mask and called "ball" when I came back up. Then I heard someone yell "hey that's a strike, he swung". I then looked to the field ump who confirmed that the kid swung, so I changed my call to strike. I just didn't see it when I was ducking. Of course, I am going to work to find a way to avoid being hit without losing vision of the batter so that this doesn't happen in the future. However, balls and strikes are not appealable calls. Does anybody suggest that it was wrong for me to change my call in these 2 cases?

Thanks.
