Pittsburgh went on to sweep the 1979 National League Championship Series, with Foli driving in a run in all three games. In the World Series, Foli had a hit in six of the seven games, but the Pirates were trailing three games to one. Facing 23-game winner and 1979 Cy Young Award winner Mike Flanagan, Foli scored the tying run and drove in three insurance runs to keep the Pirates alive in Game 5. Foli then scored a run in Game 6 against Jim Palmer and the Pirates forced a Game 7, which they won the next day to capture the fifth World Championship in team history.
