One statistic that has been bothering me lately is k/9. If one guy pitches one inning and strikes out one batter, and gets the other two out on batted balls, he has a 9 k/9. Another guy strikes out one guy in an inning but gives up 3 hits and 3 walks, and he has a 9 k/9, even though it took him 9 batters to get his one strikeout. We should measure k/plate appearance, not per 3 outs.
