Pitchers are not allowed to "deceive the runner." If the umpiring crew determines that the pitcher was, in fact, deceiving a runner with a throw over to first base, for example, it's a balk.

Horvath totally faked a fall-down between first and second, buying enough time for Reese to scamper home. That's treachery!
