Since January 2008, Mannion has overseen day-to-day business operations of the franchise, namely marketing, sponsorships, finance, ticket sales, human resources, communications and legal affairs. In his new role, Mannion will also oversee general manager Ned Colletti, who manages the team's baseball operations.
"Dennis is a seasoned sports executive who has done a great job since arriving at the Dodgers," McCourt said. "He has already begun integrating baseball operations with the rest of the organization, and today's announcement formalizes that transition."
"Connecting the baseball operation to the rest of the organization is a smart move that is good for the team," said Colletti. "I have long believed that both sides of the operation will function better as one -- both understanding the challenges each has and working together to celebrate the triumphs as one group. This move acknowledges that and I embrace it wholeheartedly."
Mannion joined the Dodgers in 2007 following 27 seasons with the Philadelphia Phillies, Denver Nuggets, Colorado Avalanche and Baltimore Ravens.
"We are all extremely proud of the team's results on the field and the direction of the organization," said Mannion. "Our talented staff on both the baseball and business sides of the organization are committed to making the Dodgers a world championship team and a world class operation."
