Singles, ie, meaning the designation of being safe at the first base which is all hits, walks, HBP, ie, OBPs What is leftover is the value of the extra bases expressed as a percentage which the SA clumsily attempts to weight by double counting the hit values again.
To put it simply, a player with 110 hits, 100 singles and 10 HR, has a hypothetical OBP of .500 with no walks, HBP, or sacrifices to keep it simple. Add the extra base value of 30 extra bases/220 AB yields 0.136% for a "true" OPS value of .500 + .136 = 0.636.
The current OPS model would yield a value .500 + .682 = 1.182.
The "singles or pure hits" are overvalued in the current OPS model. The true additional base value of the double/triple/HR becomes watered down, so a Pete Rose ends up smelling a bit better in head to head comparisons.
Let's compare Will Clark, .880 to Eddie Matthews, .885. Both fine hitters, but by OPS you wouldn't think there was more than a dime's difference between them, when clearly Matthews is the more valued hitter.
