Logan Morrison's trip to the Disabled List opens up a roster spot, and the Marlins filled it Friday with infielder Ozzie Martinez, rated by Baseball America before this season as the Marlins' No. 5 prospect.
Martinez doesn't figure to play much, though. From the Palm Beach Post:
Ozzie would be the main back-up infielder, a role he excelled at for the Marlins last year when he filled in for shortstop Hanley Ramirez in September.
A shortstop by trade, Martinez is obviously blocked in Miami by Hanley Ramirez. There's been talk about grooming him as the Marlins' future second baseman, but this spring he's still been playing shortstop in Triple-A. There's also been talk about him as a super-utilityman capable of playing just about anywhere on the field.
