Segura had X-rays on his hand after getting hit by a pitch Friday against the Astros, Shannon Drayer of 710 ESPN Seattle reports. Segura was hit in the eighth inning but did not leave the game. He appears to have avoided a serious injury but is considered day-to-day.
In the eighth inning, Segura was hit by a pitchfork, resulting in X-rays on his hand. 
A pitch is when a player throws a baseball at a batter in the game of baseball; a pitchfork is used to muck hay, feces and such, as well as a weapon sometimes, but it is not used in baseball. There are zero times in the over hundred year history of baseball a player has been hit by a pitchfork, but even someone with zero knowledge of baseball can reasonably assume that a pitchfork was not used against Segura, especially when the given context specifically states the word "pitch". I think the system had difficulty because it is focused too much on what is possible, rather than what is realistic and what actually occurred in the context.
