On Saturday night, excitement was in the air in Erie, Pennsylvania, as the MiLB's Erie Seawolves started playing under a new name: the Erie Moon Mammoths.The Seawolves are the Double-A affiliate for the Detroit Tigers,

The Double-A Eastern League Erie SeaWolves temporarily rebranded as the Erie Moon Mammoths in a promotional collaboration with HBO’s 'Last Week Tonight with John Oliver,' and the debut lived up to the hype on July 19.

The SeaWolves had no say on their rebrand name or logo. The Last Week Tonight team dug into Erie’s history to pick Moon Mammoths, a name inspired by the 1991 discovery of woolly mammoth remains in a local lake. Oliver threw out the first pitch at the game, which drew a record-setting crowd of more than 7,000 fans.
