With Dykstra as leadoff hitter, the 1986 Mets coasted to the division crown, beating the second-place Philadelphia Phillies by 21.5 games en route to a 108–54 season. The Mets ended up in the World Series after a victory over the NL West champion Houston Astros in the 1986 NLCS, 4 games to 2. Dykstra hit a walk-off home run in Game 3, which is considered one of the biggest hits in Mets franchise history and of Dykstra's career. He hit .304 in the 1986 NLCS, and then .296 in the World Series against the Boston Red Sox. But his leadoff home run in Game 3 at Fenway Park sparked the Mets, who had fallen behind 2 games to none even though those games were played at Shea Stadium. The home run made him the third Met in team history (along with Tommie Agee and Wayne Garrett, both of whose home runs also came in a Game 3, in the 1969 and 1973 World Series respectively) to hit a leadoff home run in the World Series. Following Dykstra's home run, the Mets rallied to defeat the Red Sox in seven games.
