T.R. Sullivan says that the Rangers are expected to put Mark DeRosa on the disabled list after tonight's game. DeRosa is still having ankle problems, and Sullivan says Drew Meyer is expected to be called up.
I think the Drew Meyer story is well-known...there's a good chance that this is the beginning of a relatively lengthy career spent bouncing between the majors and minors, before a manager takes a shine to him and clings to him for a few years as the 25th man on the roster (a job which he is uniquely well-suited for).
If he could hit at all, he'd probably be a useful major league regular. As it is, Meyer looks like a nice pinch-runner/defensive replacement/very occasional starter.
