Is this true? It's repeated here and elsewhere as if it is, but are we sure it is true? Has anybody studied it with any rigor? Especially today with different training mechanisms and different ways to track swing path and pitch recognition.
As for Kreidler, if he ends up not being able to establish a major league role because he can't hit RHB, that is because he just isn't a good hitter and wasn't really ever cut out for an every day role. FWIW, he always had extreme platoon splits in the minors, so he had his chances there. He's not the type of guy who don't platoon because you are worried about his long term role (if that effect even exists)
