The moments piled up, one after another, in Kansas City’s storm of a sixth inning on Monday: The crash-landing of Mike Moustakas’ game-tying two-run homer off advertising signage in right field. Omar Infante craning his neck upward as his two-run triple splashed into center. Mike Jirschele wheeling his arm to send Infante home after a throwing error. And, at last, the number “7” FLASHING on the Kauffman Stadium scoreboard, signifying the number of runs scored in the definitive inning of an 8-3 lightning strike against the Orioles. The day prior, the Royals (76-48) unleashed a four-run blitz to steal a game from the Red Sox. This time they terrorized another American League East opponent to open a four-game series.
