Career Stats Side-by-Side

Every cell below is a career total or career rate. Cells highlighted in green mark the player who leads that line. Lower ERA, WHIP and BB/9 lead; higher K/9 leads. 12 of the 16 lines below are scored; the other 4 are counting totals on which fewer is not an achievement, so no one is awarded them. Totals where fewer is not an achievement -- losses, walks and hits allowed -- are left unmarked, because they track how long someone pitched rather than how well. Rate stats are not era-adjusted, and the 2010s and the 2000s were different run environments, so read them against their eras, or use the PIV card below, which is adjusted.
