Right-handed reliever Brandon Kintzler has agreed to a one-year, $3 million deal with the Miami Marlins, according to a source familiar with the situation.

The deal includes a $4 million option for 2021 or a $250,000 buyout, a source said.

Kintzler, 35, is coming off one of the best years of his career, compiling a 2.68 ERA and 1.018 WHIP with the Chicago Cubs. The former All-Star closer with the Minnesota Twins could regain his ninth-inning role with the Marlins, who feature a young team.

Kintzler could also thrive in the new three-batter-minimum era, since he held lefties to a .163 batting average last season. He's a former 40th-round draft pick of the New York Yankees, and he has played 10 seasons. The Marlins will be Kintzler's fifth team.

The contract increases to a $500,000 buyout if he's traded this year or a $5 million option for 2021.
