We're pretty sure this was not an in game injury. Mets fans all remember Kaz as the Japanese import who couldn't handle New York, but conquered Colorado. He'll be missing the first two weeks of the season, and while my heart goes out to him, I'd rather that my mind didn't.

Yes, that's every bit as bad as it sounds:

An
anal fissure is an unnatural crack or tear in the anus skin. As a
fissure, these tiny tears may show as bright red rectal bleeding and
cause severe periodic pain after defecation. [...] Most anal fissures
are caused by stretching of the anal mucosa beyond its capability.
Various causes of this fissure include:

* Straining to defecate, especially if the stool is hard and dry
* Severe and chronic constipation
* Severe and chronic diarrhea
* Crohn's disease and Ulcerative colitis
* Tight sphincter muscles
* Anal intercourse

On three: OW. Poor Kaz. This is almost worse than Felix Pie's twisted testicle. Almost."
