F5 was not at 3B. F5 was playing back. Doesn't a good move require F1 to feint toward F5? Wakefield may have stepped to 3B, but he did not complete a legal feint to F5. Had he turned his shoulder to deliver the ball towards 3B, he may have avoided a balk call. F5 was no where near 3B and Wakefield made no attempt to deliver the ball to 3B or F5.

Wakefield separates his arms to simulate a pitch towards home plate and it is called a balk when he fails to deliver the pitch. This catches the runner off 1B. In summary, the PU may have seen what appears closer to a home to 1st move, than a legal 3rd to 1st move. That's a balk!
