Input: original question: Which sports league season has the championship event of [1979 World Series] ?
answer: 1979 major league baseball season
answer type: Sports League Season.
auxiliary information: The 1979 World Series matched the National League's Pittsburgh Pirates against the American League's Baltimore Orioles, with the Pirates coming back from a three games to one deficit to win the Series in seven games. The Pirates were famous for adopting Sister Sledge's hit anthem "We Are Family" as their theme song. Willie Stargell, pitcher Bruce Kison, and catcher Manny Sanguill√©n were the only players left over from the Pirates team that last faced the Orioles in the 1971 World Series, and Orioles' pitcher Jim Palmer, Mark Belanger, and manager Earl Weaver were the only ones who were still with the team that faced the Pirates in that same previous meeting. Grant Jackson pitched for the Orioles in the 1971 series and for the Pirates in the 1979 series. In this Series, it was the American League team's "turn" to play by National League rules, meaning no designated hitter and the Orioles' pitchers would have to bat. While this resulted in Tim Stoddard getting his first major league hit and RBI in Game 4, overall, it hurt the Orioles because Lee May, their designated hitter for much of the season and a key part of their offense, was only able to bat three times in the whole series.
