It is two different ball marks, one red and one blue, and each is accompanied by a seam indentation. They are glancing blows:

The seam indentations on the red mark do not appear to be as deep as the ones on the left barrel, and the blue ink transfers on the left barrel are smaller than the red ink transfers. It is reasonable to say that center hits leave smaller ink transfers and deeper seam indentations, right?:


So the red mark was caused by stitches because it was a glancing blow? What caused the blue mark, ink? Thanks
