 The correlation between non-close & late (CL) AVG and the difference between it and actual CL AVG is -.076. So the better hitters see an even bigger dropoff than the lesser hitters, although the effect is slight. For SLG it was -.443. So the guys with higher SLGs normally see a big dropoff in CL cases. Maybe because they are facing good relievers or don't often have the platoon advantage.

The correlation between non-close & late (CL) AVG and the difference between nonCL SLG and actual CL SLG is -.078. The correlation between non-close & late (CL) SLG and the difference between nonCL AVG and actual CL AVG is -.309. So sluggers see a big drop in their AVG when it is CL.

 The correlation between non-runners on base (ROB) AVG and the difference between it and actual ROB AVG is -.229. For SLG it was -.053. Not a surprise since that this is low because the correlation between ROB SLG and non-ROB SLG is very high (.936).

The correlation between non ROB AVG and the difference between non ROB SLG and actual ROB SLG is -.154. The correlation between non ROB SLG and the difference between non ROB AVG and actual ROB AVG is -.134. So sluggers see a big drop in their AVG when it is CL.

 The correlation between non-runners in scoring position (RISP) AVG and the difference between it and actual RISPAVG is -.292. For SLG it was -.279.

The correlation between non RISP AVG and the difference between non RISP SLG and actual RISP SLG is -.284. The correlation between non RISP SLG and the difference between non RISP AVG and actual RISP AVG is -.158.
