Owner Frank McCourt will resume overseeing the day-to-day operations of the Dodgers, as the club has severed ties with President Dennis Mannion.
The Dodgers issued a written statement Thursday night, saying McCourt would take "a more direct and active role" in managing the club. McCourt, who is in the midst of a costly divorce, had been working out of a Beverly Hills office for more than a year, leaving Mannion to run the team.
McCourt will go back to being the head of baseball operations. General Manger Ned Colletti, who reported to Mannion over the last year, will once again report directly to the owner.
Chief Operating Officer Geoff Wharton, who oversees the Dodgers' business operations, also will report directly to McCourt.
A Dodgers spokesman declined to discuss the club's plans to replace Mannion.
A former Baltimore Ravens and Philadelphia Phillies executive, Mannion joined the Dodgers in November 2007 as their chief operating officer. He was promoted to team president in March 2009, when McCourt promoted his now-estranged wife, Jamie, from president to chief executive.
