The Orioles' latest one-run loss was Saturday at Camden Yards. Coco Crisp hit a homer in the top of the ninth and Oakland beat the Orioles 2-1.
One season after the Orioles had a 29-9 record in one run games, to post the best win percentage in major league history, they are now nine games under .500 in the one-run decisions.
The Orioles have gone from first to worst in the American League in this stat and they are now 14-23 in one-run contests.
It gets a bit worse. The Orioles have lost seven one-run games in a row and and are 1-9 since the All-Star break. They are just 2-12 in these decisions since July 4.
The worst AL records in one-run games:
.378 - Orioles (14-23)
.385 - Los Angeles (15-24)
.390 - Houston (16-25)
.405 - Toronto (15-22).
The other AL East teams have winning records in one-run games with New York at 22-14, Tampa Bay 21-17 and Boston at 16-15.
The O's do have the AL's best winning percentage in two-run games, going 15-5, so there is that.
But they've gone from 20 games over .500 to nine games under in one-run contests from 2012 to 2013.
