SCOTTSDALE, Ariz. — With the Oakland A’s filing into Scottsdale Stadium for the Cactus League opener, Giants president and CEO Larry Baer acknowledged Wednesday that he could see the two Bay Area teams sharing AT&T Park at some point, but only under one circumstance.

“They’ve got to come up with a long-term plan,” Baer said. “Once that’s arrived at, then maybe you’ll take a step back and say, ‘Is there something we can do to be helpful?’ As a neighborly thing.

“Obviously, they’ve got to come up with what their plan is and we’ll go from there.”

If the A’s need a temporary home as they build a new ballpark, the Giants are open to discussions. But Baer said that there is nothing new on the A’s stadium front. He reiterated that the Giants would like the A’s to get their own stadium, but not if it’s in San Jose. The Giants hold territorial rights in Santa Clara County and have been unwilling to budge.

“If there’s anything we can do to help them get (a new park) in their territory, we’ll cooperate,” he said.
