A's president Dave Kaval never misses a chance to take a shot at the Giants and their fans.
The Giants started a trend last week when they announced they would use cardboard cutouts in place of real fans at Oracle Park during the 2020 MLB season.
On Tuesday, the A's announced they would be following the Giants' lead by putting their own cardboard cutouts in seats at the Oakland Coliseum.
A few hours after the announcement, Kaval sent this tweet.
We also have a visiting fan zone.
