Yes, and when they are large, I like the idea of platooning or juggling the line-up, at least a little bit.
On Pearce vs Moreland, Pearce has actually done better vs RHPs for a pretty large recent sample size but not career.
2016-2018
OPS vs RHPs
.789 Pearce
.760 Moreland
OPS vs LHPs
.902 Pearce
.723 Moreland
I thin, sometimes, people are blinded by the massive splits by Pearce and forget to notice that he's actually pretty good vs RHPs.
Moreland has closed his gap over the years, but .723 is still too low for the 1B position.
Another interesting Sox player is Holt. He actually has hit LHPs slightly better than RHPs (.706 to.702 career), but I occasionally hear posters talk about not playing Holt vs lefties.
