The riddle of how to keep both the Raiders and A’s in Oakland could become a little simpler as the city’s baseball team has decided to take another look at potential stadium sites outside the Coliseum complex.

Under the team’s 10-year lease at O.Co Coliseum, the A’s are required to study building a new stadium at the 120-acre Coliseum site, but the team’s co-owner, Lew Wolff, said that study has been expanded.

“Our ownership wants to take a good hard look at what our next steps are,” he said. “We want to make sure that every site that is possible is being looked at.”

The team’s willingness to consider potential stadium sites outside the Coliseum complex comes as its majority owner, John Fisher, has taken a more active role in stadium discussions, local officials said.

Wolff set up a “get-to-know-you” meeting last month between Fisher and Alameda County Supervisor Scott Haggerty, during which Fisher reiterated that the A’s were exploring multiple potential locations.

“He said they had options but didn’t talk about specific sites,” Haggerty recalled. “They want to get something built. They want to improve the fan experience; where it lands, I don’t know.”

Oakland leaders have long salivated about bringing the A’s closer to the city center with the most recent suggestion of publicly-owned land at Howard Terminal near Jack London Square.

Not only would the team’s 81 home games provide an economic boost, but getting the team away from the Coliseum complex could make it easier to keep the Raiders there. Both teams have indicated they’d rather have the site to themselves.

Mayor Libby Schaaf, who paid a visit to Major League Baseball Commissioner Rob Manfred when she was in New York Wednesday, said the city is continuing to analyze multiple options for the team.

“I have been clear that my preference is to bring the A’s downtown, but I am going to make it work wherever the A’s want to go,” she said.

Just because the A’s are taking a second look at alternative sites doesn’t mean the club will waiver from its position that the Coliseum complex still makes the most sense. Howard Terminal is far from BART and would require extensive site improvements. And it’s unclear whether the city has any other parcels of public land that could work for a stadium.

“I’m optimistic,” Haggerty said about the A’s building in the East Bay. “But I’ve noticed that sometimes being optimistic will only break your heart.”
