There are a variety of other statistics, such as on base percentage and OPS (on base plus slugging) that have been shown to more closely align with a team’s overall ability to score runs. That being said, the better offensive teams are more likely to be at the top of this list, though they’re just as likely to also have a higher on base percentage and/or OPS.
