To start, the MLB season will be played without fans in attendance. This could extend throughout the entire season and postseason as well. So some teams are offering fans to attend games in another way.
Cardboard cutouts.
The Tampa Bay Rays, Oakland Athletics, and San Francisco Giants are all offering fans to purchase cardboard cutouts of themselves to be placed around each team's respective ballpark.
For the A's, while they are more expensive, if a foul ball hits a cutoff with your face on it, the team will send you that foul ball.
