It’s no longer a secret as to what was placed inside the time capsules buried at McCoy Stadium in Pawtucket.

The city officially opened both time capsules Monday evening to mark the 44th anniversary of the longest professional baseball game in history, which was played at the stadium back in 1981.

The historic game between the Pawtucket Red Sox and the Rochester Red Wings began on April 18. The teams played 32 innings before calling it quits nearly nine hours later. The PawSox would score the tie-breaking run in the 33rd inning two months later, winning the game 3-2.

The time capsules were found as McCoy Stadium was being demolished to make way for the city’s brand new unified high school. The stadium sat empty for years after the PawSox rebranded and moved to Worcester.
