Call it Big League musical chairs.

With a "Plan A" for a new downtown entertainment and sports complex, with the Sacramento Kings as the anchor tenant, seemingly scratched, Mayor Kevin Johnson hinted at the possibility of a Plan B, or rather A – as in the Oakland A’s.

“We are watching very closely what happens in Oakland,” Johnson said Tuesday.

Here’s how the possible double play could play out.

The owner of the Oakland A’s wants to move the team to Santa Clara. Major League Baseball says that area belongs to the San Francisco Giants – who aren’t keen on letting the A’s steal it.

But the rail yards site could be just the changeup the A’s are looking for. The pie-in-the-sky possibility of the Sacramento A’s wouldn’t go exactly where a proposed basketball arena would go, but it’d be very close.

“It was landlocked, that's why I said it didn't make sense. The rail yards site north of the tracks is 200+ acres, so I think there's many acres that I think could be viable for a facility if that was the case,” Johnson said. The mayor also said arena giant AEG is still interested in Sacramento.

“They know that we're a good basketball market, as well as a good baseball market,” Johnson said. “We know that we can support not one, but two teams if given the opportunity.”
