Balk?

[DG]

The Evans Balk Video demonstrates a case where F1 throws to F3 off the bag in attempt to make a play. The video shows F3 about 12 feet from the bag, he makes a move toward 1b and recieves the ball about 6' from the bag and makes the tag. It kind of looks like a QB leading a receiver who catches the ball in stride. The obvious difference between this illustration and the on here is that it was obvious that F3 was moving to the bag to receive a throw and make a play. Not so in this example, F3 was flatfooted and likely a bit surprised by the throw and made the best of it.
