The Golden State Warriors have shunned an offer from the San Francisco Giants to build an arena on land next to AT&T Park. Instead, the basketball team is quietly exploring plans to go it alone with a spectacular waterfront arena at Piers 30-32.

For months, the Giants have pushed the idea of teaming up with the Warriors to build a 20,000-seat arena on the ballpark’s parking lot or adjoining Piers 48-50.

“This is an ownership group that is pretty bold and visionary, and the prospect of doing something grand is really alluring to them,” said one source familiar with the Warriors’ plans.

The Warriors “do not want the Giants to be their middleman,” our source said.
