A single inning can change the entire dynamic of a baseball game.
Defensively, a misplaced pitch or a mishap in the field can lead to a snowball of runs. Offensively, a few swings of the bat can open the floodgates and light up the scoreboard.
The Chicago White Stockings (now the Chicago Cubs) scored 18 runs in the seventh inning of a 26-6 rout of the Detroit Wolverines on Sept. 6, 1883, at Lakefront Park. That feat remains a Major League Baseball single-inning record.
