Career Stats Side-by-Side

Every cell below is a career total or career rate for Jason Bay and Kenny Lofton. Cells highlighted in green mark the category leader. 14 of the 15 lines below are scored; the other one is a counting total on which fewer is not an achievement, so no one is awarded it. Counting stats reward longevity, and strikeouts are left unmarked because a longer career accumulates more of them. Rate stats are not era-adjusted, and the 2000s and the 1990s were different run environments, so read them against their eras, or use the PIV card below, which is adjusted.
