I thought Martinez might be useful as depth, but I won't lose sleep if the Pirates lose him. UPDATE by Charlie: Not a surprise. I think there's a pretty decent chance Martinez gets through waivers. I think he's a somewhat better pitcher than he showed since arriving in a trade from the Giants - most of that ugly Indianapolis stat line is the result of him allowing a lot more homers than he probably will in the long run. He'll never be a rotation staple or anything, but he gets enough groundballs to be modestly useful as a Jeff Karstens type in the next few years.
