The Yankees ERA issue is attributed to 3 games only. In their 3 worst outings, they allowed 41 runs. The sox have only one game this yr where they allowed 10 runs, but they have allowed 5 or more runs 8 times thus far. The Yankees OTOH, have allowed 5 or more runs 6 times. They've allowed 6 or more only 4 times, whereas the sox have allowed 6 or more 8 times as well
