I know Ohtani will be MVP, probably in a unanimous vote, but Corey Seager is having a monster year and would be an MVP candidate in another year. He's not on the batting average leaders because of injuries, but he's hitting .350 with a 1.076 OPS while playing a key defensive position.
In fact, due to obscure rules about qualifying for batting titles, Seager would be the AL batting champion, if the season ended today. With a more than 20 point lead, he is a pretty sure bet unless he suffers another injury.
Seager struggled early last year and has suffered injuries, but he's really at the top of his game. Maybe Correa will get it going in his second year of his contract.
