Davalillo, Naranjo and Stewart all played in the Washington Senators organization. The flannel fits the style as well save for the lack of a W. I would bet if you use a black light you can see the old W outline. Not sure where DeMars would fit in here as he never played for the Washington organization as far as I can tell (maybe a spring training invite one year?). Below you can find the link to an eBay pic of Davalillo to see the jersey style.
