The Mariners become the first team to commit five errors in one inning since 1977

Seattle had a rough first inning against the Yankees

The Seattle Mariners found a dubious way to stand out Sunday afternoon in the Bronx. After taking a 1-0 lead in the top of the first, the Mariners allowed six runs in the bottom of the inning. The Yankees pounded out several hits, but they had some help as well in the form of five errors. 

Yes, the Mariners committed five errors in one inning. The blow-by-blow (avert your eyes, Mariners fans as this is definitely NSFW):

There were actually two errors by Jean Segura on the Ellsbury double, so he accounted for three errors on his own. 

Errors weren't always closely tracked, so we can't be sure about the record for errors in an inning with certainty, but the last team to commit five errors in an inning was the 1977 Cubs, reports Elias Sports Bureau. As far as we can tell with the limited history, this appears to be the most errors in an inning in Mariners history. 

Worse news for the Mariners, of course, is putting themselves into such a deep hole. They entered Sunday just a half-game out of the second AL wild-card slot.
