Performers or competitors?

Ballpark

So what is the name of the ballpark in the picture of San Francisco below?

It is not Candlestick Park as I first thought. Actually it only took a little research to find out that it is AT&T Park. It was built in 2000 and is the home of the San Francisco Giants, and is probably most famous for all those home runs that Barry Bonds hit into San Francisco Bay.
