Firing in at #66 is Nolan Ryan. The Ryan Express is the most prolific strikeout pitcher in the history of baseball. His 5,714 career strikeouts are 839 more than any other pitcher in history which is a record that ranks right at the top on the list of the most unbreakable records in sports. Ryan led the league in K/9 and H/9 innings an unbelievable 12 times each. Perhaps more remarkable, he finished in the top-5 in K/9 innings 20 times and H/9 17 times. His seven career no-hitters are three more than any other player in MLB history. He has the most shutouts of any pitcher to debut since 1942 and his 383 strikeouts in 1973 are the most in a single season in history. Ryan is tied with Randy Johnson for most 300-strikeout seasons with six and he joins Johnson as the only pitchers in history to lead the league in strikeouts four consecutive years on two different occasions.
