Both of those dudes are in the Alcides Escobar category of players you really, really should hope never appear on your MLB roster. Going to an ostensible MLB game and seeing Nomar F'in Mazara out there would annoy the hell out of me if I'd actually paid for the ticket.
Isn't Nomar Mazara basically the un-Jake Alu. Always a prospect with a good ceiling who barely performed. (edit - big bonus baby out of the DR at 16, took a while to do anything in the low minors, rushed a bit to the majors at 21 with limited upper minors time, but big hit tool per per the prospect hounds).
4 seasons as more or less a regular with the Rangers, with 20 HRs 3 times, but not really special. .250-.270.
When you put it that way, he could find time on this roster.
