The Astros won the American League West with 101 wins, and faced the Los Angeles Dodgers in the World Series. In Game 3, Peacock earned his first major league save by completing the final innings of a 5−3 win, allowing no hits and striking out four. It was the longest hitless relief outing since Ron Taylor's four innings in Game 4 of the 1964 World Series, and tied Ken Clay for the longest hitless postseason save, first accomplished in the 1978 American League Championship Series (ALCS). The Astros would then win the 2017 World Series, their first in franchise history.
