I think Thats_Nice is saying that the definition of 'error' is "messing up a routine play". I can't disagree.
In
baseballstatistics, an
error is the act, in the judgment of the
official scorer, of a fielder misplaying a ball in a manner that allows a
batter or
baserunner to reach one or more additional bases, when such an advance should have been prevented given ordinary effort by the fielder.
I'd say Mr Speaker ran 100 miles, camped under the ball, then it bounced off his head Canseco style. WIS just uses e-dice to calculate the chance of a '+' play and the chance of an error. Sometimes the dice rolls snake eyes. Just pretend the hitter got a hit if that helps.
