"torn" can mean a lot of things... none good, but judging by the fact that he's not on the DL yet, it must be considered a "minor" tear, because usually, when I hear torn hamstring, that coincides immediately with a 30 DL stint. Maybe with Matusi out, they're hoping he can DH and rehab at the same time? I don't know. Maybe they're thnking microscopic surgery, but even that would seem to imply at least a 14 day DL. I can't see him catching though with a torn hamstring, way too much crouching and getting up, that's tough enough on a catcher's legs who's not injured.
