I mean, if at bats for 2024 are the important thing, then everyone should have fun at the lake rather than worrying about the Twins.
Jokes aside, I think there is a way to view this signing positively. Gallo is basically a Kepler replacement with better defense (Kepler’s defense is good, but Gallo is a credible center fielder). He can play DH and 1B with enough power to avoid losing much if any value. Because he can play all three OF positions, DH, and corner infield, he really shouldn’t take at bats away from anyone. In my view, he doesn’t raise the team’s ceiling, but he does raise its floor somewhat.
Not exciting, but not useless. Just my two cents.
