Radical Baseball

OPS: On base percent (average) Plus Slugging average.

PA: AB + BB + HBP + SF + SH
OBP: (H + BB + HBP)/(At Bats + BB + HBP + SF)
SLG: Total Bases/At Bats or
(1B + 2*2B + 3*3B + 4*HR)/AB

OPS is a pretty good evaluation of batters. OPS+ (weighted for year and ballparks) is better but it's not available for these righty/lefty splits.

SF: sacrifice flies (fly ball out RBI) not used in the first four seasons here: 1950-1953. For instance, Mickey Mantle has 12 AB that after 1953 would not have been charged At Bats (AB) but would have been credited as SF. It may be the dumbest scoring rule of any consequence and should be removed, including adjusting past stats.

For perspective:

Lefty batters 1950-2012 batting average (BA) Monday, March 25, 2013

As documented here previously, righty/lefty splits are reliable only back to about 1950 when a high percentage of the data is derived from play-by-play data rather than from box scores. With box scores a batter's stats are attributed to the handedness of the starting pitcher.

Righty/Lefty 1950-2024 OPS splits for batters.

8 batters and starting each inning with top of order fix two dumbest things on the field.
