It is the first multiple-year free agent deal that the Pirates have put together since 2016 as they look to give a boost to one of the worst offenses in the majors.
O’Hearn had 64 RBIs while playing for the Orioles and Padres last season. He provides a bit of versatility as he’s played both first base and a corner outfield spot. The Pirates have the left-hand hitting Spencer Horwitz at first, though O’Hearn could see time there and perhaps in the outfield to play alongside Oneil Cruz and two-time All-Star Bryan Reynolds.
