It's opening day at AT&T park as the Giants kick off their home opener against the Mariners. First pitch is at 1:35pm.
The first 40,000 fans will get an opening day calendar.
At today's home opener, the Giants will have a special tribute to the late Mayor Ed Lee. The on-field tribute will include all the city's living former mayors - including Sen Dianne Feinstein, Willie Brown and Lt. Governor Gavin Newsom. There will also be plenty of pre-game fun for the players and fans, as the team celebrates its 60th season in San Francisco.
