MESA, Ariz. - With the A’s looking for a new stadium in town, plus the Warriors leaving for San Francisco and the Raiders looking elsewhere, Oakland’s new ad campaign wants to make sure you know which city the A’s call home.

“It’s not too suble,” A’s vice president of sales and marketing Jim Leahey said with a smile.

“Rooted in Oakland” features commercials shot at Oakland’s City Hall, the Oakland Zoo, Lake Merritt and BART, among other spots, all of them with the light-hearted, entertaining vibe of past ad campaigns from Hub Strategy, but for the first time ever, all of the ads were filmed in the East Bay.

The A’s announced Saturday at Hohokam Stadium that 112 flag-pole banners are going up around downtown Oakland and Lake Merritt highlighting the ad campagin, along with an 80-foot mural at 19th and Webster of an elephant carrying the city on its back.

“The organization has a good opportunity to get a lot of mind share in Oakland and areas around Oakland,” Leahey said. “We can’t control what the organizations are going to do, but it’s a good opportunity for us.”

The descriptions of the ads, which use Oakland band the Phenomenaut’s “Theme for Oakland,” from the A’s release:

Mayor Melvin - Oakland mayor Libby Schaaf thinks Bob Melvin to one day become the mayor of Oakland.

Elephant Country - On a visit to the Oakland Zoo, Graveman, Gray, and Healy lose track of Stomper, who became distracted by a new love interest.

Out For Run - A leisurely jog around Lake Merritt highlights how everyone on the A’s takes fitness seriously, including players, fans, mascots, and vendors.

BART Training Camp - The A’s are always looking for new ways to train for the season. This year, the team survives BART Training Camp, led by Hale.

Fireworks Dreams - Everyone dreams of getting on the Coliseum field, with the exception of a few A’s players who may have different dreams.
