When Dukes is ready, probably for the next homestand, Mackowiak will probably get his walking papers.
They have a decision to make, for sure. Right now, Schroder is the first to go, most likely, as we have 4 starters and 8 bullpen guys on the 25 man roster. Of course, Hill is expected back (though after today's bad start in Columbus, not a given) shortly, which forces yet another roster move.
Mackowiak or Harris, neither one has done much to warrant staying around.
