Al Oliver off JR Richard in June 1976 in the Dome, the only HR in the game. The next night we tried to get to the second game of the series but flooding made it impossible and the Astros had their first (and maybe only) official rainout in Astrodome. The following night we made it back and Oliver homered and again the only HR of the night, this time off Andujar, so Oliver hit the first TWO HRs I ever saw.
