Never saw Koufax pitch in person. Read a bit about him, including recent biography that was very well done.His career was cut short, so he lacks the longevity of some other great pitchers, but in those 5-7 years when he was in his prime, he dominated as few pitchers ever have. Every start was a potential no-hitter. Earlier in his career he was wild, so it was only a brief window of dominance before his arthritis made him retire.He also participated in one of the significant events in the history of the players' association, by holding out with Don Drysdale to force the Dodgers to bargain with them as a duo. They both refused to sign contracts one year, and the clubs exercised their option to renew them. The next year, both claimed that they were "free agents" and demanded that the Dodgers negotiate with their agent. The Dodgers refused, and both sat out spring training. Koufax talked about going into movies. Eventually, the club offered them both $100,000 contracts (very big money at the time) and they both signed. The owners avoided a confrontation with the "reserve" clause in the uniform players' agreement, but other players saw the bargaining leverage they had, and it was only a few years later that Andy Messerschmidt first tested the reserve clause (he lost, but the ball was rolling toward the players' association).If you needed one pitcher to pitch one game that you had to win to save the planet from destruction, it would be safe to choose Koufax from 1965 or 1966. Could also pick Gibson from 1968. Gooden from 1985. Pedro Martinez 1999. Orel Hersheiser -- second half of 1988.Of course, my ultimate choice would be Satchel Paige -- 1942 -- but Koufax ranks right up there.
