A person familiar with the decisions tells The Associated Press. that left-hander Jordan Montgomery has exercised his $22.5 million option with the Arizona Diamondbacks while the team exercised options to retain third baseman Eugenio Suárez and right-hander Merrill Kelly. Joc Pederson declined his mutual option for $14 million, will get a $3 million buyout and becomes a free agent. Montgomery, 31, signed a one-year deal last March worth $25 million, then went 8-7 with a 6.23 ERA over 117 innings.
