OPS combines On-Base Percentage (OBP, measuring how often a batter reaches base) and Slugging Percentage (SLG, measuring extra-base hit power) into a single number. MLB average OPS is approximately .720-.740; above .800 is above average; .900+ is excellent; 1.000+ is elite. OPS+ adjusts for ballpark and league context with 100 as average. Research shows OPS is one of the most predictive single batting statistics for run production, though OPS+ and wOBA (weighted OBA) are considered more accurate.
