Miami Marlins executive Michael Hill has been promoted to the position of president of baseball operations, replacing Larry Beinfest, who was fired Friday.
Another Marlins executive, Dan Jennings, replaces Hill as general manager. The moves were announced before the Marlins' season finale against Detroit.
Hill has been with the Marlins for 11 years and Jennings for 12 years.
The Marlins finished last in the NL East for the third consecutive year. Their loss total has climbed each of the past four years, and this season they took a 61-100 record into Sunday's finale. It has been a decade since their most recent playoff appearance.
Hill becomes only the third head of Marlins personnel in their 21-year history. Dave Dombrowski was the Marlins' general manager from 1993 to 2001.
