I would imagine in most situations the catcher has already made up his mind to throw (or not) regardless. It's not like you have time to wait for the umpire's call to throw down to second. Also, this is only a relevant question with 2 outs.
Other than kinda by definition if you're trading someone you feel ok about moving forward without them, I don't think it's at all accurate to classify the pitching Boston sent back as "spare parts".
Seeing him for the first time, his arm action feels really extreme to me. It goes really far back behind his body so there's then a long whip around when he throws it - felt like it was hard for him to get a consistent release point and know where it was going. Compare to someone like Woodruff who has a very efficient motion.
The article directly addresses this:
"Sanchez doesn't have a wealth of experience at first, having made four of his seven MLB appearances at the position in 2024 in his first stint with the Crew."
Agree, there's one scene in particular that really must be seen on a big screen, but certainly all the space scenes benefit.
It's basically a mashup of The Martian and Interstellar (in the best way).

If it resolves without surgery, fantastic, but worst case is he's not much help this year at all.
