And all three are July trade bait or October hasta la vista signings.
Look for some TC tryout signings with minor league options (and deadlines, if they're not good enough to want "fish or cut bait" clauses, they're not good enough to waste a signing bonus).
I think eventually they'll want a home grown bullpen, but can't do everything in a year or two - the veteran RPs buy time to develop young RPs in the minors.
