What Is OPS in Baseball? On-Base Plus Slugging Explained
Learn what OPS means in baseball, how on-base percentage and slugging percentage combine, and how to use OPS on Ballrecord leaderboards.
OPS combines getting on and hitting for power
OPS is on-base percentage plus slugging percentage. It answers two questions at once: how often does a batter reach base, and how much total base damage does that batter create when contact is made?
Because the two components measure different skills, OPS is a compact scouting shortcut for overall offensive value. It is not a perfect replacement for linear-weight metrics, but it remains one of the most widely searched and widely cited counting-rate hybrids in baseball.
How to interpret OPS bands
Context matters by era and park, yet rough modern bands still help readers orient quickly: around .700 is often average-ish, .800+ is strong, and .900+ usually marks an elite offensive season. Always compare against league average for the same year.
Use Ballrecord’s leaders pages to see who is pacing the majors in OPS, then open a player page for season and career context before drawing award or trade conclusions.
When OPS can mislead
OPS weights OBP and SLG equally even though reaching base is generally more valuable per unit. It also ignores baserunning and park factors. Pair OPS with OBP alone, ISO (isolated power), and available Statcast quality-of-contact metrics when those layers exist.
