That is exactly how my Giles bat is too, ball marks on right side, heavy pine tar on handle. I was a little worried by the ballmarks when I got mine too, worried another player used it, and I checked a lot of photos, and while it wasnt completely consistent I saw lots of photos where balls would be hitting the right side of his bat.
Anyway, glad to hear yours is like mine too as I think our bats combined prove this to be a consistent charactestic.
