Three Rivers Stadium opened on July 16, 1970, but the Pirates lost 3–2 to the Cincinnati Reds in front of 48,846 spectators. The first pitch was thrown by Dock Ellis—a strike—to Ty Cline. The first hit in the stadium was by Pittsburgh's Richie Hebner, in the bottom of the first inning. The Pirates lifted their television blackout policy for home games so that local fans could see the inaugural game. The Pirates' lowest season of attendance was 1985, at an average of 9,085. The average attendance would peak in 1991, when the Pirates averaged 25,498 per game. Game one of the 1970 NLCS, at Three Rivers Stadium, was the first postseason baseball game to be played on an artificial surface. The following season, the Pirates advanced to the World Series against the Baltimore Orioles. Three Rivers Stadium hosted game four, in which the Pirates defeated the Orioles in the first night game in the history of the World Series. Pittsburgh hosted its third All-Star Game in 1974. The National League won the game 7–2 and the Pirates' Ken Brett was the winning pitcher. In 1979, the Pirates again won a World Championship, yet again defeating the Baltimore Orioles in a seven-game World Series. Games 3, 4 and 5 of the Series were played at Three Rivers. 15 years later, the midsummer classic returned in 1994. With 59,568 in attendance, the largest crowd to ever attend a baseball game at the stadium, the National League won 8-7 in the 10th inning. On July 6, 1980, the Pirates beat the Chicago Cubs 5-4 in 20 innings—the most innings ever played at the stadium. The longest game at the stadium was played on August 6, 1989, when Jeff King hit a walk-off home run 5 hours and 42 minutes into the 18-inning contest, as the Pirates once again beat the Cubs 5-4. On September 30, 1972, Pirates' right-fielder Roberto Clemente got his 3,000th hit at Three Rivers Stadium, three months before his death.
