The Royals had won 111 straight games with the lead going into the eighth inning, dating to May 5, 2014.
In that game, the Royals held a 4-3 lead in the bottom of the ninth against the Padres at Petco Park, when closer Greg Holland uncharacteristically surrendered a tying home run for a blown save. The Royals fought back to take a 5-4 lead in the 12th, but then surrendered two runs in the bottom of the inning to lose.
The 111-game streak is the longest of its kind since the Yankees' 1998-99 teams won 115 in a row leading after seven innings.
"It's an amazing streak," Royals manager Ned Yost said. "It speaks to the greatness of our bullpen."
