The 1980 NLCS featured a Houston Astros team that had never been to a World Series yet, and a Phillies team that was trying to advance beyond the NLCS for the fourth time in five years.
It was these two factors—among others—that set the tone for the series and this particular game, as each player was a stone's throw away from their coveted achievement.
The game was set in a tie, before being broke open in the seventh, and with a 5-2 lead and Nolan Ryan on the mound, many Astros fans felt secure.
Not quite so.
The Phillies battled back to tie the game up at five a piece, only to see the tie broke open again and re-tied—if you can believe this—for the fourth consecutive time at seven a piece, sending the game into extra innings.
But after a 10th inning double by Del Unser, it was Garry Maddux who drove Unser in for the game winning hit, providing some closure to one of the most thrilling games in Phillies history.
