The service is available as a result of a $450,000 grant by the Mobile Source Air Pollution Reduction Review Committee.
The funding comes from a portion of vehicle registration fees set aside for projects that result in emission reductions.
"Following last year's successful launch, Metro is pleased to offer fans the Dodger Stadium Express bus service which provides a direct link to Dodger Stadium from a vast network of buses and trains coming into Union Station," said County Supervisor and Metro Board Chairman Don Knabe.
"We encourage fans to take advantage of public throughout the season to save time and money."
Last year the grant from MSRC was $300,000 and it resulted in more than 122,000 fans riding the express.
