The Baltimore Orioles have two exciting attendance milestones to celebrate this season.

Camden Yards opened on April 6, 1992 and is almost at the mark for welcoming 50 million fans to the games. If everything goes normally, that mark should be hit this season and the 50 millionth fan to enter the stadium will win…$50,000 courtesy of the Baltimore Orioles and the Maryland Lottery. If there’s something better than being the 50 millionth fan to enter the stadium this season, it’s being the 100 millionth fan to enter the stadium. That fan will win $100,000 to celebrate total attendance records in the history of the Orioles franchise.

In addition to the cash prizes, the winners will also receive season tickets and other prizes. Fans must be at least 18 years old to be eligible to win.

Fans who attend the game during one of these days, but do not win will receive a commemorative pin to celebrate the day.
