The Marlins have agreed in principle to a three-year, $40MM extension with third baseman Martin Prado, Clark Spencer of the Miami Herald reports. Assuming the deal goes through to completion, he’ll remain with Miami through 2019. While the Miami organization will obviously be glad to have retained a team leader, it’s hard to celebrate given that the team is still reeling from the death of star pitcher Jose Fernandez just days ago. Last night’s game was one of the most heart-wrenching experiences ever seen at a ballpark, with Prado among the Marlins players who took the field in extremely difficult circumstances.
