The last time it happened was by the New York Yankees against the Baltimore Orioles on Sept. 25, 1990. The most recent National League team to do it was the Pirates on Aug. 26, 1975, against the Atlanta Braves.
The Cubs had a 6-0 lead before an out was recorded, then pitcher Ryan Dempster laid down a sacrifice bunt, eliciting sarcastic cheers from the sparse crowd.
The first five hits off Zach Duke were soft grounders that either found their way through a hole or were placed fortuitously enough to be infield singles. Soto's double, however, was sharply hit off the wall in right-center.
Chicago led 7-0 when the inning ended, presumably before golf legend Arnold Palmer had even found his seat. Palmer was honored in a pregame ceremony for his 80th birthday, which is Thursday.
Pittsburgh had lost 10 of 11 heading into the game and on Monday the Pirates clinched a losing record for the 17th straight season, establishing a record for North American professional sports teams.
