It's weird not just for the negative run differential, but how close they all are. Pythag w/l:
(RS-RA)
NYY: 11-13 (104-113)
BAL: 11-11 (102-103)
BOS: 11-14 (104-113)
TOR: 11-13 (106-113)
TBR: 11-12 (99-101)
Only five teams in the AL have positive run differentials. Oakland (+43) and LAA (+30) the only in double-digits.
