The roof was closed for Friday's opener, won by Texas 6-5 in 11 innings. Rain fell Saturday afternoon and the forecast called for a possible thunderstorm in the evening.
Arizona’s Chase Field in Phoenix also has a retractable roof, leading to the possibility of the first all-indoor World Series. The roof of the stadium, then known as Bank One Ballpark, was open for Games 1, 2, 6 and 7 of the 2001 World Series, when the Diamondbacks won all four home games against the New York Yankees.
While the home team controls the roof decision during the regular season, MLB makes the call during the postseason.
