BALK?

The Nat's just took a loss due to a balk call. The call was terriable - the common balks are:
1) Pitcher deliever doesn't stop.
2) He breaks the "plane"over the rubber.
3) The pitchers body is moving towards the plate.

Anyway it was 1st and third one out bottom of the 10th. Weeks on first, Stanton on the mound and Overbay at the plate.

Stanton has Weeks picked clean... and BOOM... balk and game.
