Baseball teams reveal costs of scoreboard proposals

Monday marks the official beginning of baseball season, which also means it's the beginning of scoreboard marriage proposal season.

All 30 major league teams have revealed how much it costs to propose at one of their games. Proceeds from the proposals go to charity, but the cost varies significantly from ballpark to ballpark.

Proposing at AT&T Park on a weekday cost $145. Weekends are $175.

The O.co Coliseum in Oakland charges only $85.

The most expensive ballpark to propose at is Dodger Stadium. It costs $75 to have the message appear on the scoreboard, but it's $2,500 if you want the proposal on the video board.
