Ryan spotted Robin Ventura 20 years and a full head of steam in the fight above, and still meted out one of the classic ass-whoopings in sports history. Of course Ryan was a badass well before he played whack-a-mole on Ventura's noggin—he pitched 7 no-hitters (in three different decades, including four in just over a two-year span in the '70s)—and after, throwing a 98 mile an hour fastball immediately after tearing the ligament in his elbow that would end his career after 27 seasons.
