We got the following email yesterday evening from those in charge of the elite field for John Hancock/Boston.
We have had a few changes to the elite field:
Sara Hall has withdrawn due to an SI joint injury.
Eunice Kirwa has withdrawn due to a spine injury between L4 and L5.
Jessica Augusto has withdrawn due to a fracture in her right foot.
There are no changes to the men’s field.
Kirwa's withdrawal certainly increases the odds for an American win as there aren't that many elite foreign women capble of winning that are entered in the field. Kirwa, who is the 2016 Olympic champ in our minds (Sumgong is a doper), had won 7 of her last 10 marathons including a 2:21:17 pb in Nagoya last year.
