OPS+
OPS scaled vs league avg, park-adjusted, where 100 is average.
What OPS+ means
Baseball-Reference's analogue to wRC+. 120 = 20% above league average OPS once you account for the park.
What counts as a good OPS+
Higher is better — roughly 90 is poor, 100 average, 115 good, and 140 or better elite.
