The first four years are worth $27.3 million, and Harrison could earn a total of $50 million if the Pirates exercise both options, FOX Sports' Ken Rosenthal reports. Harrison, 27, could have become a free agent in 2018.
Harrison batted .315 in 2014, was selected to his first career All-Star Game and finished ninth in MVP voting. His .837 OPS was first among National League third basemen.
Harrison began his career as a utilityman, playing leftfield, rightfield, second base and shortstop before establishing himself as the Pirates' primary third baseman last season. Pedro Alvarez's defensive struggles cleared the way for Harrison to become Pittsburgh's starting third baseman this season.
