Plus you have a nice view of the bay and Pier 39 offers itself as a good tourist spot, so you could have regular ticket sales with people who want something to do. I went there for a Metallica concert once and the place was packed to the brim. If not, then T-Mobile Park in Seattle would be perfect.
