• 1953 - Mickey Mantle hits the longest home run in Griffith Stadium history, a 565-feet shot off of Chuck Stobbs of the Washington Senators. The Yanks win 7-3.
• 1968 - The A’s debut at Oakland-Alameda County Coliseum by losing 4-1 to Baltimore. During the game, the dirt covering a shallow metal dome under the pitching mound, is kicked aside exposing the steel frame, so the mound is covered between innings.
• 1979 - At the Coliseum, only 653 fans show up to watch the A’s beat the Mariners 6-5.
