Lazo was reinstated from the DL and optioned to High-A Jupiter on Thursday, Joe Capozzi of the Palm Beach Post reports.
The nature of Lazo's injury remains unclear, but the Marlins will keep Lazo at the High-A level after he split last season between High-A and Double-A before a brief, seven-game cup of coffee with the Marlins. If the 27-year-old fares well, he could be in line for another call up later in the year.
