Former Oakland A's players, including Trevor May and Coco Crisp, gathered with over 10,000 fans at Jack London Square for Fans Fest, a fan-run event celebrating the local community and sports teams like the Roots, Soul, and Ballers. The event featured vendors selling memorabilia, autograph tents, live music, and plenty of food and beer, creating a festive atmosphere akin to a block party.

While the event was not intended as an anti-A's fest, there was an undertone of protest as discussions continued around the A's potential move from Oakland. Oakland Mayor Sheng Thao expressed her stance on the matter, demanding that the A's name and logo remain in the city and urging for a guarantee of an expansion team after the A's potential departure to Las Vegas.

Despite some last-minute sponsor changes and controversies, the event organizers and attendees remained enthusiastic and supportive of causes like Schools Over Stadiums, a political action group opposing public funding for a new ballpark in Las Vegas. The atmosphere at Fans Fest was described as energetic and vibrant, showcasing the unity and passion of Oakland fans and former A's players who came together to celebrate their shared love for the local community.
