He's over .800 for June, so if he keeps it up, sure. Stott is .640 for June (which puts him one point behind Stubbs). Sosa .517 which is one point behind Rojas (and Pache is higher than that too). Bohm .470 and Realmuto .317 (in just five games).
Harper and Schwarber and Dahl kind of carrying the offense (such as it is) otherwise. Merrifield .714
I wonder if Pache and Dahl are going to get extra playing time until one of them has to hit waivers.
