For him and Kelenic, do we have any sense of the pitch types they've been getting? It seems like their pitching staff should have done homework and told pitchers and catchers to throw offpseed stuff.
One other thing to consider; if we are all certain that guys like Kelenic and Geno who are off to stratospheric starts will cool off soon, then the reverse might also be true: some of our guys who are uncharacteristically batting below Mendoza should eventually punch up to their weight classes.
