The most amazing thing about this chart is that Randy Johnson had an incredible 47 games with 14 plus strikeouts. Spending most of his career in the Western time zone hurt Johnson from being a super cult hero since most of the nation never saw him pitch. But he was dominate in his era. Consider what the last generation called their "greatest lefty pitcher," Sandy Koufax, only had 13 14 plus strikeout games.
This chart does give some evidence to scouts and general managers who still believe that strike out pitchers make the best starters. The most strikeout pitchers are power arms with high heat fastballs. The stats of these top 22 lefties appears to bear out that proposition. Pitchers who can strike out a lot of batters per game can have great success. It is logical because a strike out does not put any pressure on one's defense (errors, mental mistakes, failing to turn a double play, mispositioned in the field, etc.)
