If Sandy Koufax is in the Hall of Fame, why isn’t Johan Santana? The answer lies with the two p’s: perception and postseason. Koufax set strikeout records, was a mythical enigma, he was “The Left Arm of God.” Santana was a left-hander from Latin America who pitched in Minnesota, managed just one win in the playoffs, and hurt his arm. Yet, a cogent argument can be made that Santana was a better pitcher than Koufax. Yes, really. First let’s look at the similarities between the two great lefties. Both played unconventional positions as youngsters: Koufax was originally a left-handed catcher, and Santana played shortstop left-handed. Young Johan wanted to play shortstop so badly that he taught himself to throw right-handed so he could stay there until his early teens. Each pitcher had their first full season in a major league rotation when they were 25 years old. Both Santana and Koufax had to work things out in the bullpen, and took baby steps to becoming rotation regulars. Both pitchers relied on pinpoint control of their fastball, though Koufax took longer to tame his speed pitch (which was faster than Santana’s by about 6-10 MPH). Santana and Koufax both had six-year runs that are among the most dominant stretches of pitching since the end of the deadball era. Koufax won three Cy Youngs during his peak, while Santana won two and finished in the top five four straight years, just like Sandy. Both pitchers led their league in many categories: Koufax won four strikeout titles and Santana won three; Koufax led the league in ERA five times, Santana three times. Santana and Koufax both led their leagues in innings pitched twice. Both pitchers helped their team to the postseason four times. Both pitchers threw no-hitters, though Koufax tossed four and Santana one.
