In the 1980 NLCS versus the Philadelphia Phillies, Ryan pitched well in Game 2, leaving the game tied 2–2 in the seventh (having contributed to both Astros runs with a run scored following a walk, and a sacrifice bunt leading to a run) but again got a no-decision in a game that went extra innings. In the fifth and final game of the series, Ryan and the Astros held a 5–2 lead entering the 8th inning. But Ryan allowed three consecutive singles before walking in the third run. The Houston bullpen allowed the Phillies to take a 7–5 lead, and only a game-tying Astro rally permitted Ryan to escape the loss.
