T.R. Sullivan reports that Adam Melhuse has made the Rangers roster as the backup catcher, and Jarrod Saltalamacchia is heading for AAA.
I think the writing has been on the wall on this for a while now.
Sullivan also says the only roster issues unresolved are who the last two relievers will be (although one of those relievers will only be on the roster until April 12). There seems to be a sense that Robinson Tejeda will get one of those slots, although that doesn't seem to be set in stone just yet.
