all season long, even during the playoffs. In 2017, new team President Dave Kaval decided to open several sections in the original third deck that were covered by tarps, though Mount Davis stayed tarped. This increased capacity by 12,103 to 47,170. The Athletics have since occasionally removed the tarp on Mount Davis for specific games, such as occasional Bay Bridge Series games against the San Francisco Giants, and the 2019 American League Wild Card Game against the Tampa Bay Rays. The latter set a record for attendance of a Wild Card Game, at 54,005. Sewage On June 16, 2013, following the game against the Seattle Mariners, the Coliseum experienced a severe sewage backup. This led to pipes leaking out puddles of sewage into the showers, offices, visitor training room and storage areas on the clubhouse level of the stadium, all of which are below sea level. After the game, the A's and Mariners were forced to share the Oakland Raiders locker room, located on the stadium's second floor. According to Coliseum officials, the stadium's aging plumbing system was overtaxed after a six-game homestand that drew close to baseball capacity crowds totaling 171,756 fans. This was not the first time sewage problems cropped up at the stadium. On one occasion, the Los Angeles Angels complained about E. coli in the visiting team's training room after a backup. Backups occur even when no events are taking place there. For instance, Lew Wolff wanted to go to dinner on June 12, 2013 (while the A's were on the road) at one of the Coliseum's restaurants, only to discover that food service had been halted due to a sewage leak in the kitchen.
