Campbell '25 at 2b
968 Fielding % MLB
949 Fielding % AAA
Even ignoring widely used metrics, there's no way Campbell is coming back to BOS as a 2b. It has nothing to do with Cora and everything to do with Campbell's athleticism and inability to field the position at a high level. The best fit for him is 1b/LF, but that puts more pressure on the bat.
