With the Astros, Bochy was behind the plate in Game 4 of the 1980 NLCS versus the Philadelphia Phillies when Pete Rose ran over Bochy to score the go-ahead run in the top of the tenth inning. Bochy was the backup to Terry Kennedy when the Padres won their first NL pennant in 1984, and he played in one game in the 1984 World Series, which the Padres lost in five games to the Detroit Tigers. On July 1, 1985, Bochy hit a tenth-inning walk-off home run off Nolan Ryan of the Houston Astros, the only walk-off home run allowed in Ryan's career. Bochy was behind the plate on September 11, 1985, when Pete Rose, now with the Cincinnati Reds, collected his record-breaking 4,192nd major league hit off Padres pitcher Eric Show.
