Having been assigned the task of tossing the ball from the pitcher's mound to the catcher just over 18m away, with the entire diamond to aim for, the woman proved unable to meet the challenge.
A local photographer, who had casually inserted himself to stand 5m clear of the strike zone inside the in-field to capture the woman's throw would soon regret his decision.
The woman lined up and proceeded to hit him right in the melon from an almost impossible position.
There was a chorus of laughter from across the stadium as the woman went to retrieve the loose ball that had rebounded off the photographer just in front of the mound.
The photographer, who had fallen to the ground, got back to his feet with a grin on his face.
A man claiming to be the poor bloke beaned in the head later confirmed both he and his camera were in one piece.
He was able to capture some incredible action shots of the moment his life flashed before his eyes.
Fortunately for the woman's sake, she is just one of countless fans to make a fool of themselves on the mound.
Here's just a small taste of some of the better ones.
For those that remembered there was a baseball game to be played after the woman's atrocities, the White Sox eventually went on to beat the Kansas City Royals 2-1 in a game that stretched over two days because of rain delays.
Pitcher Alex Colome had a perfect no-hitter in the ninth innings as the Sox pulled out of their 2-6 losing streak.
