I mean, he wasn't the reason they lost today (having 1 hit in the first 8 innings was the primary one) but Boone obviously saw what Freeman did yesterday in the last at-bat, swinging on the first pitch for the grand slam, and tried to overcorrect for his mistake of bringing in Cortes.
Judge's underperformance is a bigger problem than their manager
Freddie Freeman is an elite batter. Trevino is a battler.
When is the last time Boone is the reason we won a game?
If this was in the regular season - Judge would get a night off and clear his head and freshen up. The other alternative is to Put Judge at 2 and Soto at 3. That way Judge will see better pitches as they won't want to face Soto. Simple flip.
