Free-agent reliever Derek Law and the Arizona Diamondbacks are in agreement on a minor-league contract that includes an invite to MLB spring training, sources say. The deal pays $1.5 million if Law is in the majors and includes $500K in potential incentives, sources say. And now he has a realistic chance to make an impact on the major-league roster for a Diamondbacks team that has continued searching for bullpen help this winter. It’s possible that the Diamondbacks are not done bolstering the major-league roster. But their latest move is adding Law on a minor-league contract in a move that gives the bullpen some much-needed depth.
