De Los Santos was traded from the Diamondbacks to the Marlins along with Andrew Pintar in exchange for A.J. Puk on Thursday, Jeff Passan of ESPN.com reports.
De Los Santos has always had plenty of raw power, and he's translated that to game action this season by posting a .324 ISO with Double-A Amarillo before being promoted to Triple-A Reno. He has 28 total home runs across 87 games between the two levels and could provide some needed thump to the middle of the Marlins order in the near future. For the time being, De Los Santos will likely report to Triple-A Jacksonville.
