In 1978, the Pirates came from fourth place and games behind in mid-August to challenge the Phillies for the division title and the teams met in the last regular-season series of the season to decide the division title. The Phillies arrived in Pittsburgh for a four-game series ahead of the Pirates by on September 29. The Pirates swept a double-header to extend their winning streak of home wins to 24 and to trim the gap to games. In the third game of the series, Willie Stargell hit a grand slam home run and it looked like the lead would be cut to half a game. Instead, Phillies pitcher Randy Lerch hit two home runs to help the Phillies come from behind to win the game, 10–8, to win their third straight division title on the next-to-last day of the season. This was the first time that visiting teams won a division title at Three Rivers Stadium. In the postseason, the Phillies lost for the second year in a row to the Dodgers in the 1978 National League Championship Series.
