I just realized Franco has the best WAR in baseball. What a joke.
Franco's WAR value is driven by his defense, which has been good.
I think the broad view is that in the National League, the MVP frontrunners are Acuna and Carroll.
In the American League, it's pretty clearly Ohtani. There is a case for Bichette, if you don't want to double-count Ohtani's pitching stats with his hitting stats, though I think the only real threat to Ohtani's MVP campaign is Aaron Judge if he returns and remains hot.
While I don't think the voters will actually give it to him, Fernando Tatis Jr could wind up having an MVP season at the end of this -- even with him missing games because of suspension. He's probably going to lead the NL in WAR even with the missed games.
