Radical Baseball: Righty/Lefty sOPS+ splits 1950-2024.

For 75 seasons, using a different stat: sOPS+. From the Baseball Reference glossary for splits:

sOPS+ -- OPS for split relative to League’s Split OPS

A number greater than 100 indicates this batter(pitcher) did better(worse) than the league in this split.

A number less than 100 indicates that the batter(pitcher) did worse(better) than the league in this split.

League averages are for the major leagues as a whole and include pitchers’ batting.

sOPS+ is not park-adjusted.

Data derived from:

https://stathead.com/tiny/S3FFV

In the Regular Season, from 1950 to 2024, vs RHP (within Platoon Splits), requiring Plate Appearances >= 328 and On-Base Plus Slugging >= 1.000, sorted by greatest On-Base Plus Slugging.

373 records found.

In the Regular Season, from 1950 to 2024, vs LHP (within Platoon Splits), requiring On-Base Plus Slugging >= 1.000 and Plate Appearances >= 114, sorted by greatest On-Base Plus Slugging.

729 records found.

373+729=1102

...

ALL records have OPS >= 1.000.

A table was created that contained a record for each of the 75 MLB seasons 1950-2024. It contains the minimum PA for each season for (vs RHP) and (vs LHP). That number is based on MLB splits each season for the number of outs credited to the pitchers. Using that, 892 records were selected as eligible from the 1102 found in the two queries in stathead.com.

It was based on a total of 500 PA. If the percent of outs credited to LHP was 30%, then the minimum PA (vs LHP) for batters is 150 for that season and 70% (350) for (vs RHP). Here are the first ten seasons:

Cliff Blau said...: That Dick Allen 1966 split is crazy. His split OPS+ was 293!; Thursday, April 10, 2025 at 6:12:00 PM EDT

___________________________

That comment initiated the consideration of sOPS+.

Data resorted on sOPS+. (500PA) PAlefty and PArighty are the minimum required Plate Appearances for batters to be included against pitchers throwing with that arm in that season. See the partial matrix above.

Barry Bonds has the highest sOPS+ against both (vs RHP) and (vs LHP)

Top n for vs RHP: (top 31 of 199 records with sOPS+ >= 180)
