Now, I would say the "Mookie only hit XXXX against lefties!" is not a good argument against the move. 60-game platoon splits for a hitter are nearly worthless from a predictive standpoint.

If all you knew about a hitter was 246 PA, I have generic platoon splits as ~93% of model
Mookie Betts is only at the point in his career in which his actual platoon splits (-12 point advantage against lefties) are about *equally* as predictive for future platoon splits as a generic righty& #39;s platoon splits.
We have enough of Betts that we should only be predicting a 15-20 points-of-OPS advantage against lefties rather than a more normal 40-50 point one.

The argument for keeping Snell in (which I favor!) has little to do with Betts platoon splits.
The argument for keeping Snell in is a much simpler one: He was pitching well, efficiently, styming the Dodgers, and he& #39;s not starting again for at least five months.

No reason to complicate things unnecessarily!
I know it might sound like an odd thing for a notorious number-cruncher like me to say, but if you& #39;ve read my work, you may be surprised how few stats I actually use in direct writing.

Stats guide an intellectually honest story, but they& #39;re not typically the story themselves!
Unless we& #39;re talking fun stuff like records or .400 BA things, stats are far more important for what they *mean* than what they *are*.
And analytics largely help you reach *an* answer, not *the* answer. As long as we& #39;re not talking crazy stuff like giving Ian Desmond a five-year contract to play first base/corner outfield, they don& #39;t usually *demand* a course of action.
