Soto and Realmuto for me and it's not even close.
Haven't been able to get going with Machado yet but he's going to get a long leash with those stats. Devin Williams is also disgusting but I've only got 2 IP so far so.
Realmuto online stats-
.778 avg, 5 hr,, 7 rbi, 3 bb, 1 k. 3.278 OPS. he's 7 for 9 with 5 hr's, that swing is outstanding.
