[UmpTTS43]

... thing I have ever read in ANY baseball publication concerning rules. 2010 FED rulebook. pg. 37

"Turning the shoulders to check runners while in contact with the pitcher's plate in the set position is legal. Turning the shoulders after bringing the hands together during or after the stretch is a balk."

And to think that the people that come up with this stuff are actually trying to make the game "easier" for the umpires.

I really hate this time of year when I have to read the FED book, just to get the cobwebs out.
