Dalbec to Anaheim for CF Brandon Marsh?
If Devers isn't going to 1b, Dalbec is blocked. Putting him at 1B doesn't really do much, as that position can easily be filled with a hitter more likely to contribute and it doesn't take advantage of Dalbec's biggest strength.
Anaheim doesn't really have a 3B. They did use Tommy La Stella in his breakout campaign last year, but he can also play 2B. Marsh is unlikely to see outfield time in Anaheim with Upton-Trout-Adell in front of him and Ohtani holding down the DH role...
