First Base: DJ LeMahieu
If the Yankees want to win the world series in 2021, they must resign DJ LeMahieu.
LeMahieu finished fourth in MVP voting and was named an all-star in 2019 with the Yankees as he slashed .327/.375/.518 with 26 home runs and 102 RBI’s.
He has continued that pace in 2020 as he’s slashing .355/.404/.524 with five home runs and 13 RBI’s.
LeMahieu plays both second and first base at a high-level thus, to accommodate other moves to assemble the dream lineup, starting him at first would be the move.
