When Roger Clemens signed with the Blue Jays in 1997, his dominance continued as it did in Boston. He won back-to-back Cy Young Awards and this cap was worn during the second of those Cy Young years. This is a traditional Blue Jays blue cap with the logo on the front. Clemens signed the bill of the cap and it rates a strong 8. On the inside of the bill is his number 21 written in marker.
