The first public event at the Astrodome was an exhibition game between the Astros and the Yankees on April 9, 1965. That exhibition game was arguably the most ballyhooed christening of a ballpark up to that time... Total attendance was 47,876, at the time a record for an indoor sporting event. Yankees legend Mickey Mantle began the game with a single, and in the sixth inning blasted the first indoor home run ever.
Standing outside the clubhouse with lifetime batting averages less than .300 and at least 1500 hits are 445 players... Among the outsiders is Mickey Mantle, who expressed the following: 'My biggest regret was letting my lifetime [batting] average drop below .300. I always felt I was a .300 hitter, and if I could change one thing, that would be it... But, god-damn, to think you're a .300 hitter and you end up at .237 in your last season, then find yourself looking at a .298 average — it made me want to cry.'
Batting lefty against the right-handed Fischer, Mantle swung and connected with a fastball from Fischer. The blast hit the façade of the Yankee Stadium roof in right field, approximately 370 feet from home plate and 120 feet high, barely missing leaving Yankee Stadium entirely.
Famously, Mickey Mantle's widow, Merlyn, asked "the Preacher" to deliver the eulogy at Mickey's funeral service in 1995. The Mantles were at Roger Maris' funeral ten years earlier when Bobby recited a poem that a fan sent him, and Mickey made Richardson promise that he would read it at Mickey's funeral, too.
Meanwhile, in-game footage was filmed during the 1957 season when the Senators took on the Yankees at the real Griffith Stadium... Could that be Camilo Pascual on the mound for Washington? That must be Yogi Berra catching a foul popup. In the sequence, Joe Hardy/Joe Boyd makes a game-saving catch off the bat of none other than Mickey Mantle.
