When the Dodgers traded for Trea Turner at the deadline this year, they knew it would take some movement on defense. Corey Seager is in a contract year and really hasn’t played anywhere else in his career at most levels.
So naturally, it made sense for the Dodgers to slide Turner over to second base. The offensive slide of Gavin Lux opened up the spot and made it much easier to plug him in there on a daily basis. But it also took Turner learning a brand new position on the fly.
