On July 21, 2018, the tarp on Mount Davis was removed by the A's for an interleague matchup against the Bay Bridge rival San Francisco Giants in a successful attempt to break a Coliseum attendance record. Tickets were sold for $10 apiece. In 2019, the A's again opened Mount Davis for fans during the Bay Bridge Series against the Giants and for the 2019 American League Wild Card Game against the Tampa Bay Rays. With the tarps off for the wild card game, they set a record for the highest attendance at a Wild Card game at 54,005.
