In the wake of the team’s threats to relocate to Las Vegas, A’s fans are organizing a “reverse boycott” to remind the world that the A’s fandom is still very much alive. The boycott isn’t just a protest, fans hope to make it a full party.

Their theme: Sell the team, John Fisher.

“It might be something that doesn’t make a difference, but it’s going to be a night for the fans,” Hal Gordon, also known as Hal the Hot Dog Guy, said. “If you are someone who has had nights at the Coliseum, a lifetime or a season, it’ll be a fun way to bid those memories goodbye.”

The festivities will start today once the parking lot gates open hours before first pitch at 6:40 p.m. against the Tampa Bay Rays. Independent fan groups that include the Oakland 68s and Last Dive Bar are organizing a tailgate they expect to turn into a party. They’re serving up tacos from Tacos El Ultimo Baile and drinks from Old Kan Beer & Co, both out of Oakland, with a hired DJ to lend a soundtrack to the event.

They’re also getting petty to let out some of their frustrations.

Bryan Johansen, a part of the Last Dive Bar fan group, designed cornhole boards — one with Fisher’s face on it and the other with team president Dave Kaval’s face with holes cut out of their open mouths. Johansen and the Last Dive Bar are responsible for a majority of the player banners that hang from the left field fences.

He’s printed brand-new ones he plans to drape over the facade targeting Fisher, primarily. He’s printed shirts and a banner with the words “That’s just dumb” on it, referencing a Nevada legislator’s comment during a hearing on the Las Vegas stadium bill about the state using taxpayer money to fund a new stadium. They’ll also be handing out thousands of cheer cards to fans.

The Oakland 68s will hand out their free fan giveaway at the tailgate and various posts around the parking lot. In collaboration with local clothing brand Oaklandish, the drumming group crafted thousands of green shirts with “SELL” printed in white across the chest for fans to grab and wear at the game. They raised more than $30,000 in donations to produce the shirts, getting contributions from local fans as well as supporters from across the country and overseas.

Fans are ensuring that the seats are full by giving away for free a couple hundred tickets, some to those who can’t afford it otherwise.

Jeremy Goodrich, an 18-year-old Santa Cruz native who runs the Twitter account @OaklandRooted, procured and gave away 200 tickets through fans who had extras and couldn’t attend themselves but wanted to support. Tickets went only to fans who wanted to attend but couldn’t afford it.

“Since the A’s raised ticket prices, some families are unfortunately unable to afford them,” he said. “We are happy that these people will now be able to go to the game on Tuesday.”

Goodrich says fans of other teams — including the Chicago White Sox, San Francisco Giants, Tampa Bay Rays and Chicago Cubs — reached out to donate tickets for the fan giveaway.

Johansen and the Last Dive Bar group gave away more than 100 tickets to fans. The Oakland 68s received a donation of 100 tickets that they gave out to fans who emailed. Tickets ran out quick.

Some on social media have a manual count of more than 20,000 tickets sold for the game, well over the league-low 8,675 average the Coliseum hosts this year. Plus, they’ll welcome a beleaguered A’s team that returned to Oakland on Monday off a five-game win streak.

Players would never admit it, but it’s not easy to play without that key ingredient to a home field advantage. Chalk part of their historically bad record to start this season up to playing in front of historically small Oakland Coliseum crowds. The reverse boycott could be one of the biggest home crowds this team sees this year.

“There is truly something special about Oakland A’s fans,” Goodrich said. “The fact that we are still fighting so hard after being treated so horrible says something.”
