If you are looking to use public transportation to get downtown to Petco Park, there is some helpful information on the sdcommute site. It is not the prettiest or clearest, but it does explain how to get to Petco Park using San Diego’s fleet of public transportation, including bus, coaster, and trolley service. Good luck!
Also, remember this is San Diego we are talking about. Have you considered arriving by Water Taxi across the bay or the ferry from Coronado? Or what about hopping into a car2go or uber?
