My brother noticed it today when we were watching on tv the red sox vs yankees game today -saturday.And he asked me and i had no idea.But several of the yankees jerseys on the back mlb logo it was blue and light blue and not the normal blue and red on the logo.All we could guess is that these are the jerseys they wore from back in the fathers day thing.But i thought those jerseys had the blue ribbion thing sewned in to the jerseys also.Is there any yankee experts who know why the logo colors are different.
