Back with more Calcaterra! He has a list of each team's most memorable home runs.
Not a game-winner — in fact, they lost the game — but Billy Hatcher hit a homer in the bottom of the 14th inning to tie the score 4-4 in Game 6 of the 1986 NLCS. They went on to lose in the 16th, but boy howdy that was somethin’.
Yes, that was a nice one. But I'm thinking about Chris Burke's 18th-inning homer as the most memorable. Maybe July 27, 2007, when Adam Everett hit his 2nd homer of the day against Edgar Gonzalez. Just because it was so freaking shocking.
Other great moments in Astros homer history:
October 18, 2004 - Jeff Kent's walk-off in NLCS G5
October 9, 2005 - Brad Ausmus' 9th inning, game-tying HR, setting up Chris Burke's blast.
