The Guards are doing one thing especially poorly...

We suck so far at ABS challenges. Our hitters are 1 for 7 on their challenges, and our catchers are 1 for 5 on theirs. (Dashboard is here - https://baseballsavant.mlb.com/abs)

That appears to be the worst in the majors, and by a fair margin. Let's hope that adjusts quickly, because those scant opportunities can literally change the complexion of a game.
